Mac OS X for PPC (Mac OS 10)

thanks, but I was on a "chicken/egg" situation, no blank DVD DL and my mini's HDD was reformatted. I thought I had the 10.5 DVD, but alas no, so the win10 PC was the only way to make the DVD (mind the mini's combo drive does not support DL)
BTW, I found the solution: I d'loaded the 10.5.4 (8GB image) then using TransMac on PC I restored it on a USB/Firewire external HDD, then used that HDD to install on the mini G4

Sure guys the Single_DVD_Leopard_Install.cdr is bootable? I am unable to boot it on my mini G4 (A1103). I imaged on a DVD-R on my PC using the ImageBurn from your site, still on boot (startup) its not recognised.

Didn't have more time than to upload the image, it's something thats requested every now and then since DL DVD's seem to be harder to find, and are a bit more expensive. As usual, all the extras need to be unticked before attempting to install

It'd be fine to get the 10.5.6 DVD as well, if you want to upload it.

I have Mac OS X Leopard Install DVD and Mac OS X 10.5.6. Should I upload this Mac OS X 10.5.6 DVD ? Do you have this already on your page ? Is Single DVD Leopard install.cdr is Mac OS X 10.5.6 ?

After a lot of kernel panics trying to run the installer 10.4.6 (Tiger 4 6.dmg)on my G5 (Powermac 11,2) (Burn a copy on a different system, clone the image to a small partition etc..), the only thing I didn't test was burning a DVD on the G5 burner which has Leopard installed. Went ahead and burned it, then it worked!! Succesfully installed Tiger now..

OS X Leopard doesn't work
Hopefully I didn't burn too much DL DVDs.
The others OSs work perfectly fine.

I burned successfully a bootable Tiger DVD for a PowerBook G4 on a Windows PC this way:

1.: Extract the Tiger_4_6.dmg.zip on a Mac (i used OS X 10.5.8) with the built in unarchiver (don't use 3rd party apps)
2.: Command-Click on the Tiger_4_6.dmg -> Open With -> Disk Utility
3.: In the window Command-Click on the image file -> Convert "Tiger_4_6.dmg"
4.: Now select the destination where to save and the Image Format -> DVD/CD master
5.: You'll get a 3.53GB image file with a CDR extension, which is just a ISO file. So you have to rename it to Tiger_4_6.iso
6.: Now you copy the image file over to a Windows PC and burn it to a DVD-R disc (i used a old TDK DVD-RW @ 2× burn speed) with a decent program (i used Nero 8).
7.: With this method it should boot with the disc flawlessly, i had no problems with the installation. Good luck!

I'm using macOS Sierra.

This is a great library of software.

I have seen to run into an issue though. I have gone through several DVDs and I can’t seem to make my 10.4.6 dmg bootable. I download it, extract it from zip, and then burn in disk utility. When inserting into my iBook, the optical drive never even spins long enough to tell me it is bootable or that a disc is inserted, it just ejects. The optical drive plays normal DVDs just fine though. When reinserting to my daily Mac, it reads the disk as a Tiger install DVD. Any idea what’s happening? I’ve read some comments about the DMG needing to be locked...not sure if mine was locked when I burned.

Thank you

So I have no clue how to make an actual Panther/Jaguar bootable disc. Disk Utility (the new one) says that both sets of images aren't bootable. And I've tried the discs on my iMac G3 and it doesn't restart. Any help would be appreciated!

Firewire must be built in. If you get the machine running again I would start with an earlier OSX (ie 10.2) and try to upgrade from there. I would not run Tiger on anything less than a 400MHz machine.

I edited my last msg so hope your getting all this...
Sounds like maybe you need a pram battery, pram reset, or pmu reset. My Mirror Door G4 runs without any battery, has no clock set on powerup, whereas a weak low voltage battery might choke the system. Your G3 may or may not require a charged battery...

@nd2003grad, my Tiger Installer disc says in its system requirements that a Firmware Update on the computer might be necessary to make the install work, and, mactracker says Firmware Update(s) were issued for the B&W pmg3.

Another nagging possibility is the various disc "drivers" were dropped from the disc image, I haven't checked the download. I would use OSX Terminal with the disc mounted then type "diskutil list". Maybe you don't have OSX and need OS9 to perform the same test? My computer G4 can install from discs missing the driver set, but your G3 is so much older that maybe yours needs these drivers. I wouldn't use driverless discs anyway on my G4 because it could let the OS appear to run but have minor detail misbehaviours due to missing disc drivers when installed. One of the OSX install disc driver partitions is in excess of the standard set, the extra partition is named "Apple_Driver_ATAPI" and my Tiger nonspecific DVD has a "4KB" Apple_Driver_ATAPI. It happens a lot that people share copies not containing the driver partitions. I'm not sure how .toast handles them, or the .toast could be an image of a copy, not necessarily the image of an original. Check for them.

The apple logo (grey on white) means booting has successfully left the firmware mode and the media bootloader has begun. But in the time prior to the progress spinner appearing, it's very low level hardware concerned. This could be failing you due to having a weird PCI card installed, or a keyboard/mouse plugged in a hub before plugging into the host USB. Stuff of that sort. Without knowing more about your sys, I assume you have another earlier OS in working order, and you are booting from an optical drive proven to boot other OS installers?

Do you get the spinning progress wheel under apple, or is that blank? Do you have the minimum RAM capacity?, Tiger requires 256MB. Do you have native FireWire ports?, I've heard Tiger requires it, mactracker says B&W G3 ("Power Macintosh" not "PowerMac" yet) has the FireWire. If not, there might be a hacked Tiger Install disc here on mg which bypasses the FW requirement.

Hi sfp1954, double-clicking did not help at first. Probably I had allowed keka to take over and it became the default "open with" application.
But your tipp triggered the right moves: I changed the default "open with" app to Tiger's BOMArchiveHelper.application and voila – everything works just fine. The file is ok, then. Cheers and
thank you very much!

I have downloaded the zip-files for 10.5 from both servers. I cannot unzip them, neither in unarchiver nor by using the unzip command in terminal.
Unzip gives me this error message:
"Archive: /Volumes/…/Leopard_10_5_4.dmg__0.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of /Volumes/…/Leopard_10_5_4.dmg__0.zip or /Volumes/…/Leopard_10_5_4.dmg__0.zip.zip, and cannot find /Volumes/…/Leopard_10_5_4.dmg__0.zip.ZIP, period."
My browsers fail to cope with mega so that road is closed to me. Any help would be appreciated.

It depends on the computer model - some Macs can boot of external drives, some can't.

It also depends on the drive - some older drives (internal or external) can't read re-writable CDs, and some even older drives can't read writable CDs either.

I got on my PPC iMac G5 running Leopard and downloaded Toast 6 and I followed all of sfp1954's steps and it still did not work I'm lost but so far I do appreciate everyones help so far.

Wait so what you are saying for the .toast files is that I have to go out and buy a copy of Roxio Toast?

I really want to use these files and I love how they are all gathered in one place but please can someone tell me how to actually use these??? I want to make a bootable cd or usb out of them and I want to know if I need disk Utility or some other 3rd party sources. Thanks

Hi Nana, that the files you are trying to preserve are for Classic Mac OS 9, you should be able to perform a clean install of OS X Tiger, without damaging or losing your OS 9 installed files. A clean install of OS X would replace the earlier version of OS X that you have, but leave the OS 9 install intact.

Are you able to back up all of your current files that you wish to keep, to an external hard drive (just in case things don't work out)?

Would this G3 iBook go on the internet as described here ? I am worried about running out of CD-R discs before I get the downloads sorted out.
Create a FireWire Network
FireWire can also be used as a networking interface. How do you go about that? Simply use your "Network" preferences pane, in the System Preferences application and check the "Built-In FireWire" port in the "Network Port Configuration" list. Then, link your devices together as you would with regular Ethernet cable and you're free to go; just make sure that both devices are configured to use FireWire as a networking interface, or you won't go very far.
Bought new CD-Rs in case mine were too old. Made 4 new Tiger discs. The process said "Checking your installation CD," etc but still get message
"You cannot upgrade this version of Mac OS X"

Ciao Gazza,
were you able to solve your problem? Sorry for the late question, I just read your problem now. If you need I can burn the Tiger CDs for you and send it to you. (I can test'em as well before send on a G4 iMac) I am also in Italy.
Ciao
