Tommy is a Cherokee garage mechanic, refuting his heritage and undecided about his next step in life. His world comes to a halt when an extraterrestrial crisis forces him to awaken spiritual powers from his long-forgotten birthright. Abducted with his people to a menacing mothership orbiting Earth, he sets out to save himself, his girlfriend, and eventually, the entire planet.


Tested, a nonsense keycode does not work, & this does:
D23B-DPBA-BCRP-TABP-15 (enter without dashes).
Of note this is described around town as a code for the PC edition, and, they also recommend disabling your internet connection during when the code is input.

Another, Mac specific, keycode is found in the "Manual link" (pdf) at this page top-right.

Requires DVD in drive to launch game, unless: Patched!
Burnt copies are not working yet ~ use the patch.

Game is available from the Mac App Store for Intel Macs, use the Purchase link at top-right.

Don't let these published system recommendations scare you, I've played Prey on a "Mirror Door" 2003 G4 physically slowed to 950 MHz on a 100 MHz CPUFSB without altivec and only 64MB VRAM. The game video options lets you reduce resolution and complexity to compensate for slower hardware.

awesome game, I bought it from the app store for intel macs but I like playing on my g5 better.

A polite convention is to not replace the (Prey) unix executable file, instead rename the original to be "Prey~" then add in the patched "Prey" file.

This is a valid keycode too:
2222222222222222 09

Is the Carbon API named after "Carbonite" from the movie The Empire Strikes Back ?
They knew when they were making it that the API would "become frozen" to closeout OS9 and prevent future incompatibilities. In the movie, Han Solo becomes "frozen in Carbonite".

I've replaced the patched executable with a nicer version that is the same size as the original executable. Using the "file" command on this new patched executable now shows the two architectures in the same order as the original.

Great, tho sounds like it's so heavily protected (from your own description) that burning this won't work either.

I deleted the cdr image, after comparing that all data in it and yours are identical. Also, that cdr image was writeable and had been mounted by someone in 2011 so that its root DS_Store file was no longer original. Your .toast file seems read-only and its DS_Store file unchanged since 2006 as should be.

Indeed, the original DVD does have partition scheme and map chunks. I've uploaded my Toast disc image, which gives identical output from "diskutil list" compared to the original DVD.

NucAr, the patch (and game) works on my G4, High quality 1280x800 is a little clunky, I'll have to reduce the video settings a bit more. Game looks the same with AltiVec disabled, so far, it might run on really fast G3. Smile

Bad .cdr file is now deleted. I played out my own advice by renaming the .cdr as .toast, I gave it the toast creator & type codes "CDr3" "GImg" to let it open my Toast v5.2.1 on double-clicking the file, I locked it before ever mounting it to prevent image distortion, and Toast burned it to a 4.7 GB DVD+R to show this could be done, but still had the same problem as 2 other people did : DVD not recognized as authentic. Maybe it needed to go on a 8.5GB disc, but doubtful. More likely it's this:

The .cdr image here is missing any and all partition scheme chunks, rare for any real disc. Probably means the .cdr here was created by scanning only the "Prey" partition, not the whole device, using Disk Utility. NucAr you said you have real disc, you can confirm by mounting real disc and then typing "diskutil list" in Terminal, does "Prey" partition exist alone or is it supposed to be preceded by some partition_scheme/map chunks?

I've uploaded a patched version of the Prey executable that bypasses the DVD check. To install it, right-click or control-left-click and go to Contents/MacOS, where the Prey executable is. Unzip the patch, and replace the original "Prey" executable with the patched one. I created this patch using HT Editor 2.1.0 built after installing Xcode 3.2.3 (includes GCC 4.2.1) in Mac OS X 10.6.8. I followed the method given here: (same thing, text version)

I patched both the Intel and PowerPC portions, and combined them back into a universal binary using the "lipo" command, as the article above describes. On an Intel Mac, you can test whether the PowerPC patch works by running the application under Rosetta (under Get Info), but the in-game performance will be terrible. The game should play well on a sufficiently fast G5.

I'm not surprised that aurelios69's burned DVD didn't work. The game's disc check may be rather sophisticated, perhaps DPM-based. Using the original DVD, I can hear the disc drive taking a few seconds to perform checks on the DVD before the game finally opens. I tried creating an Alcohol 120% disc image (.mdf/.mds pair) with DPM enabled, but maybe DAEMON Tools for Mac 2.3, with which I mounted the disc image, does not contain DPM functionality, as the game was not fooled. This method, however, does defeat the SafeDisc protection that, for example, LEGO Indiana Jones uses. SafeDisc is not DPM-based.

What OS and software did you use to burn the disc and what OS are you trying to launch from ? Maybe it'll work if you try renaming the .cdr to .toast and use Toast to burn? Is your DVD drive external or internal (what connection cable)?. trivia: this game originally sold on 3 CDs, the 1DVD version is enhanced and/or for macs.

Yaknow, the keycode in page description was bad!
It was missing the first four characters and I repaired it (but I haven't tried it yet). And there's another keycode in our "manual link" (pdf) official Mac version, also try code:

I'm about to try this game/download. Lots of people call it one of the best video games ever. It spent a little over 10 years being created ... and another 10 years making its 'sequel'. It will be fun to see if my 1.6 GHz G4 with ATI Radeon 9600 can play this, not precisely meeting the sys requirements. If not, my C2Duo with ATI X2600 should.

old: the "Carbon" API framework can technically be employed by OS9-only and OSX-only apps, but for the reason behind the framework's existence, a smooth transition from OS9 into OSX, the definition of a "Carbonized" app ought to mean that individual app runs when launched by both OS9 & OSX.

Thanks for the help but it doesnt work with me.
Ive bought the game, the physical disc on ebay and some german web store that I found on the comments were at M.G.

The game isnt working, even after I burned a DVD it still asks for the Prey disc. Sad

If you're trying to run the game in Mac OS X, then you could try this:

  • Right-click / Control-click on the "Prey" app and choose 'Show Package Contents'
  • Then open the folders Contents -> MacOS
  • Open a new Finder window and start Terminal (in Applications/Utilities)
  • Drag the Prey icon from the window into the Terminal window

Just double-clicking the original Prey application icon gave me the "Insert CD" message, but using the 'Terminal trick' (from the mounted disk image) seemed to get further ... but I don't know if the game actually works since my Mac doesn't have a compatible graphic card / chip, so the display went wonky and I had to do a forced reboot.

There is a new "reimagined" / "reboot" version of this game made by Arkane Studios released recently (May 2017) for PS4, Xbox One, and Windows PC. I don't know if a Mac version will appear or not.

Hi. So I have burned the game to a DVD using BURN on my 2008 Mac Pro. However, when I copy the PREY folder over to the hard disk, and try to launch the game, it just says PLEASE INSERT THE PREY CD in the drive or press quit. I have the PREY CD IN the drive, but it never seems to recognize it. Did I burn it incorrectly?

Ay help any one could shed on this would be great.

   if the application was PPC and ran exclusively on OS X then it was not carbonized.

Not necessarily so. Carbon is an API used in developing Macintosh software to 10.6 & beyond. If the software is not "classic compatible" it doesn't mean its not Carbon. The OS X Finder was a Carbon app up until 10.6 and Adode Photoshop was a carbon developed app until 2010. The Carbon API was finally depreciated with Mountain Lion 10.8 - For more info see Wikipedia article

Whether the above is "Carbon" or "Cocoa" I couldn't say, but there is a good chance that it shares a Carbon.framework as it runs on PPC as well.

Carbonized? Are you sure? I thought carbonized PPC applications ran under both OS 8/9 and OS X and that if the application was PPC and ran exclusively on OS X then it was not carbonized. Also if this is a universal binary (with PPC and Intel listed on the page), I thought this did not include Carbon. Am I wrong?
