This system has Rosetta 2 include.

I hope this will survive much more macOS releases than Rosetta 1 has.

Apple have announced to new apple system at WWDC. The new apple system is macOS Big Sur 11.0. This will be coming out this fall.

macOS Big Sur 11.0 beta 1 intel x86-64 and ARM64 is Apple silicon and Rosetta 2 is included as of macOS Big Sur to aid in Apple's transition to ARM processors from Intel processors.[5][9] In addition to the just-in-time (JIT) translation support available in Rosetta, Rosetta 2 includes support for translating an application at installation time, effectively creating a Universal 2 application.

In time Apple will remove all non-apple silicon intel x64. This needs x64 intel remove future mac to ARM64. This system has Rosetta 2 include.

Well, I briefly looked it up, and found this one video by ever-famous dosdude1, reporting that he can install, specifically, 10.7.2 on Core Solo/Core Duo (but nothing past 10.7.2, not even 10.7.3). The video is from 2014.

Interesting. Now I wonder what's the latest OS X version people pushed into 32-bit x86 machines since. Not that anything past Snow Leopard would be particularly good on them, since most 10.7+ apps will naturally tend to be 64-bit only, although exceptions most likely exist.

Edit: Yeah, people pushed this further. For anyone potentially interested, look up "oemden DOT com" and things like this video.

Fun trivia.

From memory, I know that Lion did still load 32bit kexts, namely those for the GMA950 GPU.
So I presume that 10.7 would still work on a 32bit CPU even as the 64bit kernel goes first by default.
The 32bit kernel must still be there, maybe flaky and undocumented.

I never saw much advantage of 10.7 over 10.6, so my C2D oldie stays with Snow Leopard.
It does boot Sierra just fine too. Wink

@SolarstrikeVG Is there any unofficial, known way of booting 10.7 Lion (and later) on 32-bit x86 hardware? I thought Lion and later came distributed with only a 64-bit kernel.

On a side note, I once looked up "re-enabling" Rosetta on Lion, but it turned out this would require modification of the Lion kernel (Rosetta is that deep-rooted into the system), and thus also require the recompiling of the kernel.

On a side note, once Intel becomes comfortable here (probably not for some time but we'll see); we'll probably have to search out for the last versions of programs for Snow Leopard due to both Rosetta and the lack of official 32-bit EFI support on 10.7+. (Lion tweaks and 2006 MP EC scripts not withstanding)

This probably won't be for some time though due to some programs supporting SL as late as 2015 if not even later (Firefox supported SL until June 2017, VLC in November 2017, and so on) - though games will probably be rolling in around 2022-24. (most devs dropped SL support in the 2012-14 range)

Don't expect an upload on this page until 2021, at least for now.

This at happen on other website about MacOS Catalina. This website has change to intel 64 and windows. is website is moving to intel 64. has move to intel 64. has remove all 68k and power pc but intel only and and will be new techtool 12 in fall. has remove all buy link to universal games and hint books these games. They have to remove to intel 64. has remove all PCI and PCIX cards. And left only PCIe on website. G5 or intel to run PCIe but there are 2 card work on G5 only but not mac os 15 64bit. Some cards work better on intel 64. has two version on website. old universal and newer intel 64 but new intel 64 in alpha version. The old universal is still on website but have testing too build for intel 64. all pangea Software games will not run on MacOS Catalina 64 bit. Most games have gone to intel 64 but some have not. all free games are universal. some buy games are intel 64 but some are universal. from Richard Bannister website. His application are mac OS X 10.11 or later is 64 bit.
This is from website. It said this.
First and foremost, breathe. Everything is going to be ok!

Best case scenario, you only have newer games which are already 64bit compatible and an upgrade to Catalina would not harm a thing.
Worst case scenario would be that you install a prior macOS on a second partition so that you have both the newer Catalina, and the older Mojave (or Sierra) to run your older games which died in Catalina.

So you are wondering if you should Upgrade to macOS 10.15 Catalina (as your Software Update may be pressuring you into). You may first want to make considerations about the Applications you currently have and use (especially ones you wish to continue to use for awhile yet). Not only games, but all your non-Apple Applications are subject to this change.

As with all macOS updates that break prior games in your library, Catalina is no different (except that it will break a lot more than usual). Upgrading to Catalina will cause all 32bit-only Applications to cease functioning! You will not even be able to launch them.
Game Developers have known about this impending change for many years now, and many new Mac Games are designed with 64bit support. However not all are 64bit compatible!
Keep in mind, the MacGameStore is a store and service that sells the games made by developers. MacGameStore does not make these games, and can not update them to 64bit without source code. When a developer provides an update to a game, we will post the updated game (if we host the download).
Games provided through 3rd party systems (like Steam) are also under the same limitations and restrictions. Some games on those services will see updates too from their developers (but not all, especially really old games).

If you are thinking of upgrading to Catalina:

Many games will not run!
Pay close attention to the "64bit Support" line in the "System Requirements" area. We try our best to gather the full information from developers and publishers, however sometimes they are still unknown.
We also have added '64bit' badges on product lists for all 10.15 users using the MacGameStore App.
Sadly, MacGameStore can not issue refunds for older 32bit-only games you bought beyond the allowed return period. If you dual-boot anyhow, those games can still be played fine!
If you have an older Mac that ran 10.14 (or earlier). You can still setup a dual-boot on another partition for those games (it may be daunting, but its a viable solution).
Ultimately, upgrading to Catalina is your choice to make. Hopefully this information helps you decide.

Further information about this transition and the change from 32bit to 64bit, and other helpful documents:

32-bit app compatibility with macOS High Sierra 10.13.4 and later
Steam and macOS 10.15 Catalina
Installing macOS on a separate APFS volume

Steven Peeler has said this on his on blogs.
Dropping Mac support

We've supported the Mac platform for 11 years now, but yesterday Apple released OSX 10.15 which removed support for 32-bit applications. Basically that means that our games (and probably tons of other games and apps) no longer work on the latest version of OSX. It's certainly possible to fix this on our part, but the following is why that's not feasible.
• 32 bit apps no longer supported - This is the initial, direct problem. This is mostly changing to compiling as 64-bit application, fixing any compile problems, and then lots of testing and fixing any problems that crop up. This part is probably not too bad.
• Apple's Carbon API is 32-bit only - Pretty much all of our Mac specific code is using the Carbon API. We would need to rewrite all of this to use Apple's newer Cocoa API.
• Other libraries - Going from 32-bit to 64-bit is likely to break some of the libraries we use. Hopefully this just means we would need to update to a newer version, but it's possible we would need to go to a completely new library or write it ourselves.
• Now required to be notarized by Apple or app won't run - This is basically just getting an automated tool to run against your app. The process itself is probably pretty easy, it's the requirements that would cause issues for us. These can be seen at here.
• Notarization requires OSX 10.13.6 - This requires a jump of multiple OS versions for my Mac. The reason why it's on an older OS version, is because, in my experience, every new version of OS X breaks something in my developer tool chain.
• Notarization requires signing the app - This should be relatively easy.
• Notarization requires XCode 10 - Just like an OS X upgrade, XCode upgrades tend to break something in my developer tool chain and again this would be a jump of multiple versions. Also XCode requires 10.13.6 (at least that is consistent).
• Notarization requires an app to link against the OSX 10.9 or later SDK - This would force us to make the min OS we support as 10.9, so this would screw over customers on older OSX builds or I would have to make 2 Mac builds.
• OpenGL is deprecated - Apple hasn't completely killed off OpenGL, support but they have announced that they are phasing it out to support their Apple only Metal API. We don't even support Microsoft's platform specific graphics API.
• My Mac computer - My current Mac computer max OS that I can install is 10.13 (2 behind the latest). So I can barely get to the min OS version needed by Notarization and XCode. How long until Apple forces me to buy a new computer?
• How long until Apple drops Objective C for Swift? - Given everything else in this list, how long until Apple completely drops Objective C for Swift. Currently all of our Mac specific code is in Apple's Objective C language. It's already annoying enough that the Mac specific code is in a different language (we use C++), but being forced from one Apple language to another Apple language would be worse. Considering I would already be rewriting most of the Mac specific code it would make some amount of sense to get this over with now. Note: learning a new programming language isn't that big of a deal, it's just one more thing added to the long list.
• Gatekeeper Path Randomization / App Translocation - This has already partially broken our games before 10.15. This makes it so our games can't access our own data because it's not included inside the app bundle. Fixing this isn't hard, but it's annoying to need to fix it in the first place.

So the final list of things needed to continue supporting the Mac: move to 64 bit, transition carbon API code to cocoa API, probably replace some of our libraries, sign the app, notarize the app, upgrade Mac to 10.13, upgrade to XCode 10, transition OpenGL to Metal, transition Objective C code to Swift, restructure directories, fix everything that broke in all of these upgrades, and probably buying a new Mac computer sooner than later (and Macs are expensive).

I'm sure Apple has a good reason for all of these things, but a company with $250 billion in cash pushing all of this work on much smaller developers is kind of a crappy thing to do.

All of this would take more time than the initial port to the Mac in the first place. While the initial porting turned out to worth it, our Mac revenue has gone down a lot since then. So doing all of the above would be a pretty big money sink and unfortunately that is not something that we can handle right now.

NOTE: All of our current games that get patched will continue to get Mac patches. They just won't work on 10.15 and above.

I got this from this website but 32 bit application has not been removed from mac app store. Old 32 bits application are left on site. It was wrong on this site. Buyer beware 32 bit app don't work on MacOS Catalina.
But no new 32 bit application are upload to mac app store. Only 64 bit app are upload to mac app store.

Apple removed 32-bit-only apps from the Mac App Store.

Not quite true. Apple hasn't removed any 32-bit apps from the store. As an example, you can still find Return to Dark Castle today on the Mac App Store as a 32-bit app.

It will even let you purchase and download the app on Catalina, even though it's not at all compatible. Surprisingly the Mac App Store gives no indication that this is the case.

The only change that happened around 32-bit apps with respect to the Mac App Store is that the store has stopped accepting new uploads of 32-bit apps since January 1, 2018.

mac os 10.5.1 Catalina

Support for 32-bit applications is dropped. Only 64-bit applications can be run; older 32-bit ones will no longer run. This includes all software that uses the Carbon API. macOS Catalina runs only 64-bit applications. That means 32-bit applications will no longer run, including all software that uses the Carbon API and image, audio and video formats that use QuickTime 7. Apple removed 32-bit-only apps from the Mac App Store.

mac os x 10.6 last system run on x86 32 bit intel computer and x86 32 bit and 64 bit and Power PC 32 bit in Roswell emulator. mac os x 10.7 to macos 10.14 run on 64bit computers and 32 bit application. All developer will will changing to 64 bit.
That will send all x86 32 bit and 32 bit Power PC and universal will be come here on macintosh garden. They will come here because it will only place to get the old application and games.

With High Sierra, Apple introduces minor changes in how they ship ESD. High Sierra InstallESD.dmg is contained in xarball 'InstallESDDmg.pkg'. No longer are BaseSystem.dmg and AppleDiagnostics.dmg contained in InstallESD: with High Sierra, these three images are distinct. Previous InstallESD.dmg slice/partition/filesystem Volume Name was 'OS X Install ESD'; with High Sierra, Volume Name is 'InstallESD'. Previous AppleDiagnostics.dmg partition-scheme was Apple partition map (APM); with High Sierra, AppleDiagnostics.dmg uses GUID partition-scheme (GPT). Disc images (InstallESD.dmg BaseSystem.dmg AppleDiagnostics.dmg) are UDIF read-only compressed (zlib) UDZO (still, since Mac OS X Lion).

Another little news story:

I am not alone in disliking how Apple ships OS X ESD. See blog post: René Rebe » Blog Archive » The miserable High Sierra install experience.

I might have found a trick, a way to get an older "point release" of OS X from Apple's software distribution network. By actioning 'Store > Check for Unfinished Downloads…' instead of 'Purchased > Download', an old minor version of OS X El Capitan was downloaded (.2 15C50 rather than .6 15G31). Payload UDIF file 'InstallESD.dmg' is different than 2016 December, and the bingle gods did not index its checksums.

Interestingly, disk image partition is unchanged, same as it was at 2016 December. Any change is in Universal Disk Image Format meta information.

Attention !
Apple seems to have changed some certificates rendering all OS X installer ESDs useless after 02/14/2016 if they were downloaded before that date. You need to reload the installer ESD with the new signation OR, as a work-around, to set the date to before 02/14/2016 for the installer running successfully.

After fourteen hours, El Capitan 15C50.dmg download successfully completed. (A bogus error around 5,2Go scared me. For a moment, I thought about ten hours of traffic and electricity was wasted.) El Capitan seems to be first OS X which is shipped with GUID partition-scheme (GPT). (Every other OS X which I observed, both CD and ESD, use Apple partition map APM.)

2016-03-23 follow-up: 15E65 download completed after little more than one hour. Maybe Apple beefed-up their software distribution server network.

2016-07-22 follow-up: 15G31 download likewise completed within two hours.

2016-09-23 follow-up: time to download 16A323 was just fifty minutes. It is considerably smaller than El Capitan.

I dislike Apple Universal Disk Image Format "UDIF.dmg files". I discourage use of UDIF.dmg. I strongly discourage treating UDIF.dmg as a "gold master", "original composition", or "reference copy". I believe, UDIF.dmg is likely to be mishandled by innocent non-experienced oblivious users, who will false-positive-detect 'data rot'. This might result in wasted operator time & effort, material waste (if operator chose WORM media), and wasted network resources. I consider UDIF.dmg harmful.

I now realise hdiutil convert UDIF.dmg -format UDTO is a futile operation. It loses meta information from UDIF. Before, I wrongly assumed it outputs a normalised file with added "gold" value for reference.

In the interest of software preservation, I will emphasise volume/slice/partition/filesystem content of UDIF.dmg over container file itself.

I am not alone in distrusting Apple's competence to deliver/distribute software. See recent blog post: Michael Tsai - Blog - No One Minding the Store

I just read a somewhat relevant, little news story:
Apple Pulls Older Software From 'Purchased' Tab in Mac App Store (story at

This does not surprise me. Years ago, I did expect distribution to be discontinued. If I am surprised, then it is because Apple has distributed old O.S.s through so long.

later edit:
I read another little news story:
Discontinued Apple Software Returns to 'Purchased' Tab in Mac App Store (story at

The software titles were returned to list of purchases, but availability/distribution was not restored. 'Purchased Tab' is like a receipt, a record of titles which App Store account is licensed to use; rather than a 'software locker', garage/library of items offered for retrieval.

If we removed everything off this site that wasn't official abandoned by its publisher (even including publishing companies that no longer exist), we would probably have one Zip disk filled with shareware (OK, so a bit of an exaggeration, but not far off).

Try posting a 20+ year old EA game on this site, and see how "reasonable" some software publishers can be!

Apple have NEVER released any of their software as abandonware. I would not pick a fight with Apple (or their lawyers) and many current computers in use are stuck at maximum Mac OS X 10.6.8 (particularly MacBook's which cannot update due to video hardware). I personally used Lion as my only OS until quite recently (Mid-2010 iMac).

Almost all current software will run on 10.6.8, so my piracy concerns are well-founded when we talk about "preserving" an (Apple) operating system still in regular use around the globe.

As you can see, a steady 1 in 5 users (at that point) were still using Snow Leopard, probably out of necessity. NO APPLE OS WILL EVER BE ABANDONWARE. It might be FREEWARE, but that is as far as Apple, and its litigious mentality will go. Even then, only System 6.0.8 and 7.5.5 were ever released as freeware (from memory).

The simple fact that we would even CALL Snow Leopard or Lion ABANDONWARE, shows how little you know about Apple, and ABANDONWARE.

Many here will agree its wise to preserve everything from Apple locally as long as its available.
We had to learn the hard way that servers may go off-line in an instant.
Thinking of support, we have to face the fact that the ntp security update was not offered by Apple for 10.7 or lower.
(Don´t ask me why they decided not to submit this simple patch and leave this large barn-door open for attacking.)
Anyway we should recall the ten-year rule before even considering uploading files to the garden.
Posting links to external servers, may they be legal or not is useless in my opinion, as this won´t preserve anything and thats what the garden is about, don´t you think so?
Just my two € cents.

discussing anything more recent than that is courting disaster

discussing is courting disaster ?!

Here is some discussing on Apple Support Communities. Do you call this 'courting disaster'?

I do not understand you. I live right now. I do not see 'pirating' going on. Not in discussion, nor anywhere else on Macintosh Garden. Do you see 'pirating' now? Or in future? I very much doubt some 'pirating' will 'get this site shut down'. I guess the admins could shut it down, but I do not know why they would want to do that.

I want to understand you, but I find your posts non-reasonable.

As far as I know, MacOS9 still gets online system (software) updates... so we are in very muddy waters indeed if you go by that rationale.

iTunes comes preinstalled as part of the OS, and not a part of iLife (as it once was). The fact that they dropped Safari support is probably due to XCode and Apple trying to force users to update (why they would upgrade due to a Safari update is beyond me).

I don't give a sh*t about anything Apple offers to Windows users, as this is not a Windows site. I would very much care if this site got shut down over pirating "recent" versions of Mac OS X for Intel computers...

10.4.7 Server and 10.5 "might" be OK, but discussing anything more recent than that is courting disaster.

We have only recently agreed posting software here that runs native in Mac OS X 10.1/10.2/10.3 on the Garden.

butterburger's picture
by butterburger - 2015, January 2 - 12:40am

iTunes is a software product separate of Mac OS X. iTunes is pre-installed and bundled with Mac OS X, just as games, AppleWorks, and FAXstf might have been bundled in past. A user might accept Mac OS X Apple Software License Agreement, and reject iTunes SLA.

Software Update distributes software titles (mostly Apple software) and updates to software titles (mostly Apple's). Mac OS X and iTunes are two of Apple's software titles. If a Mac user removes or uninstalls iTunes, then Software Update will not offer 'minor' or sub-version updates for iTunes. Then, Software Update will offer a new release of a previously removed software. A newer major version of, iTunes in this case, can be either: an upgrade from older version, or a newly-installed title.

Why Apple presents new iTunes, but not new Safari, to users of Mac OS X Lion? I can tell you, but I am slanted, so consider this false: iTunes rakes in money; Safari does not.

This has nothing to do with anything: Safari, iTunes, QuickTime, and more, were presented to Windows users in Apple Software Update.

This has nothing to do with anything: Microsoft Windows Update and Apple Software Update both distribute drivers. If a new HP Printer Driver is added to Microsoft Update Catalog or Apple Software Update catalog, for an end-of-life operating system, then that does not mean 'developer of old OS still supports old OS'.

Clear as crystal?

I think everyone has their own opinion on what's abandonware. In the case of OS X, in my eyes, if the OS can get updates via "Software Update", can't be called abandonware. Fresh installations from Tiger and up get their updates just fine.

And a note about Lion: It is still getting the current iTunes version. A couple of days before christmas, those with Final Cut installed got the proapps codecs update 2.0. Apple could just deny such update to Lion users, but didn't. Even if it is not getting new security updates can't see it as completely dropped.

Just to clarify what we call "Classic Mode" is the ability to run OS 9 under OSX, Classic was dropped with Leopard. What was dropped with Lion is the ability to run PPC applications on intel machines. Snow Leopard with the aid of Rosetta is the last OS that can run PPC applications.

I can foresee issues for this website if we link to any OS above 10.5, although there is good reason to make 10.6 available for Classic Mode (I thought it was Classic that was dropped in 10.7 and Rosetta dropped in 10.6?). My memory is pretty hazy tho.

Retail versions for Tiger were all PPC only except for one Server edition, 10.4.7, which was Universal Binary. All Intel releases were bundled with the computer they were sold with and were machine specific. All Leopard releases, whether retail or machine specific, were Universal Binary.

Lion is still sold by Apple so can hardly be regarded as Abandonware, especially as it last received an update as recently as September this year.

Kitchen2010's picture
by Kitchen2010 - 2014, December 29 - 5:24pm

Correct me if I am wrong, but didn't Tiger and Leopard retail CDs/DVD include the Intel binaries in the install? If that is the case, then these are already covered in another thread. They are not abandonware either.

Mac OS X 10.4 Tiger had different Install DVDs for PPC and Intel, Mac OS X 10.4 Server came with Universal Install DVD for Intel/PPC. Mac OS X 10.5 Leopard came as a Universal Install DVD.

Apple do not support any OS older that is more than 3 generations behind the current OS (support for Mac OS X 10.7 Lion was dropped this year with release of Mac OS X 10.10 Yosemite). So it became abandonware in my eyes. Moreover, they give the current Mac OS X away for free (since Mac OS X 10.9 Mavericks).
So it is fair to have these abandoned OS somewhere for everybody who wants his old Macintosh still around and wants to use it for something useful.

The creator of this entry wanted to list the information of the Intel Mac OS X for future reference. I think links would be OK up to Mac OS X 10.6 (last Mac OS X with Rosetta for running PPC applications).

There are a LOT of macintosh computers that cannot run anything higher than Lion (32bit EFI). To say Snow Leopard and Lion are already abandoned is ridiculous in the extreme. I know two people in my town who are happily using 10.6.8 on their MacBook Pro's. They cannot actually go higher due to no graphic card support in 10.8/10.9/10.10.

As far as I know, Apple have not made ANY operating system abandonware, and are staunchly against the idea. I know they are fervently trying to get people to update to Macericks/Yosemite due to a high percentage being reticent to do so. This does not diminish the fact that Snow Leopard and Lion are still very much sold and supported by Apple.

If any of these OS you mentioned ran on PPC, that would be a different matter.

Correct me if I am wrong, but didn't Tiger and Leopard retail CDs/DVD include the Intel binaries in the install? If that is the case, then these are already covered in another thread. They are not abandonware either.

I would have started with Tiger and Leopard, if I had any discs to checksum. What do you see as the problem? Other software pages in here, point to vendor/developer/publisher sites to purchase. Mountain Lion will be abandonware next year. Snow Leopard and Lion already are abandoned: new copies are sold only as base from which to upgrade to current latest OS; use of Lion and earlier is not any more supported than Leopard and earlier (which already are found in Macintosh Garden). This page will help us to detect 'data rot'. Our work is software preservation.

This page has nothing whatsoever to do with piracy.

themacmeister's picture
by themacmeister - 2014, December 28 - 12:21am

This gives me a bad feeling. Software this modern on what is essentially an abandonware site, just doesn't sit right with me. You know that Apple is going to pull those links down at their leisure, when not enough people have upgraded to 10.11, which then requires more mirrors (Amazon/eBay), and before you know it, people are posting links to Torrents or DropBox.

This is just too close to piracy for comfort. The simple fact that you supplied links to their Purchase page on Apple, confirms that these are still supported and sold by Apple.

This thread deserves to be on an OS X related website, just not sure if this is the correct site.
