Running Mac OS X Tiger on x86

Running Tiger on an Intel machine is now possible, even to dual boot Win XP and Tiger

3. Appropriate therapy for hormonal abnormalities (e.g. How long does cialis take to work? factors in the individual patient must be emphasized..

. For you who are interested of trying this here follow a short tutorial.


  • You do this on your own risk.
  • Please do not attempt this if you feel uncertain.
  • And do not ask for support from me.

You aren’t allowed to use this guide to install OSX on your PC if you are not an Apple developer! This guide only shows you that it is possible and tells you something about partitioning! So: Buy an Apple from if you want to run osx!


  • To run Tiger on x86 you must have at least a SSE2 compatible processor.
  • Mac OS X Tiger image file. (It is illegal to download this file from bitorrent by searching for “tiger-x86.tar.bz2”.)
  • dd for windows.
  • chain0
  • You need an additional hard drive for this, a single partition will not do.


  1. Uncompress the Tiger file.
  2. Create a new partition of type “0xaf” on the empty hard drive.
  3. In command prompt type make sure to hit enter between every line:
    • DISKPART> Select disk (DISK NUMBER)
    • DISKPART> Delete partition
    • DISKPART> create partition primary id=af
    • DISKPART> Exit
  4. Open command prompt and input this “dd if=(path)tiger-x86-flat.img of=\.PhysicalDriveX, where X is the number of you empty Hard disk. If you type the wrong number here it wipes your primary disk, so be careful

    . This takes from 15 min to several hours so be patient.

  5. Copy chain0 to your root drive (C:).
  6. Add this line to boot.ini C:chain0=”Mac OS X”
  7. Reboot, you should now be able to dual boot XP and Tiger.
  8. Tiger are now running very slow so using the Finder go to “/System/Library/Extensions/” and delete the file “AppleTPMACPI.kext” in this folder. You may need to authenticate with your password (bovinity) to delete it . Reboot and your computer will spring to life.

Please do not attempt this if you are unsure about your hard drive numbering and do not come here asking for help when your entire primary hard drive is wiped out
. Happy Mac’ing.

    Hi, I’d like to know what do you mean to make a partition of “0xaf” type I can’t find a filesystem of that type.
    Cna you suggest me a program to make that type of partition??
    Bye Mik

    Diskpart is a program in Windows XP ant the 0xaf are the file system for Mac.

    In Widows XP command prompt type:

    DISKPART>Select disk (DISK NUMBER)
    DISKPART> Delete partition
    DISKPART> create partition primary id=af
    DISKPART> Exit

    Make sure to hit enter between every line.

    I tried!
    But when I reboot after loading the kernel the system show a message in 4 languages in graphical mode to reboot the system.
    I tried to change options to load kernel (safe mode -x) but nothing.
    Any idea????

    Yes, It is illegal to download this file from bitorrent by searching for ‚Äútiger-x86.tar.bz2‚Ä? but How i can have ‚Äútiger-x86.tar.bz2‚Ä? or “tiger-x86-flat.img ”
    Thank you

    Mac OS X su Pentium4

    E’ possibile far girare il sistema operativo Mac OS su di un normale PC ?

  6. 16 years ago  

    now this is interesting…

    and my brother was saying that it’s possible and i didn’t believe him. i think i’m going to have to see this for myself.

    jiabby – you can buy a Mac OS X Tiger CD. :) or a Mac. well i’ve got a Mac already, and the Tiger install disks. but i thkink it might only be an upgrade disk. welll, i’ll see if i can do this.

    what is the worst thing could happen? if you did something wrong?

    Well John,

    That’s a tough question but I’ll tackle it.

    The worst thing that could happen?

    Hmm. Let’s say that you get to the DD part and select the wrong disk drive. You’ve just wiped your main hard drive and deleted windows.
    Now let’s say you’re in school and all your term papers *were* on your desktop. Now you’re screwed. You fail all your classes that semester, and since you were on academic probation anyway you get thrown out of school.
    You have to move back in with your parents, and share a bedroom with an alcoholic uncle that molests you when your parents are gone, but they don’t believe you. Your girlfriend’s friends all told her to dump you when you got kicked out of school, so now you have no school and no girlfriend. You tried calling Apple for help getting your disk back, and when you told them what you were doing they sic’ed the BSA on your ass, and now you’ve got a subpoena to appear in court for software piracy. As part of the discovery, the BSA get evidence from enCase that you have thousands of .GIF’s of underage Malasian boys on your former hard drive partition, and they turn over the evidence to teh FBI, who prosecutes you as a sexual predator and puts your picture on CNN. Now you’re going to federal prison.

    That’s sort of a worst-case scenario.

    Just try to follow cleverly all the instructions. Everything find since I can double boot and the apple is shown when I select mac os x disk but during the startup of macosx system, it just stops… All I can see is the big Apple and the round counter stops. I check my AF partition doing a detail partition in diskpart and it seems OK: “partition Type: AF, Hidden: Yes, Active:Yes, No volume associated with this partition”. My computer is sse2 compatible. What could it be? I got ram bus memory. Could it be the problem? Antoher compatibility problem??? Any tip is welcome.

    Steve O,

    Sounds like the program is not recognizing your dvd drive. Is your dvd drive in the master or slave position? Try putting it in the master position and retry the install. I had the same problem and making the dvd drive the master solved the prob. I now have a native install on a second hdd.

    It may be illegal.

    Now, iv got a question, iv instlalled with a the image but the partition is only 6gb. How can I extend it?

  17. 15 years ago  

    Joe you should just try to wait …. loading for the install takes for ever.

    i have an empty hard disk with ntfs file system and when i try to do the diskpart section i get the messages “there are no partitions selected”
    and when i enter the create section i get “DiskPart was unable to create the specified partition”
    do u have a clue here?

    I have the same problem with only 6gigs, and cannot use Partition Magic, as the program is too big. I’m stumped. But I will try partitioning my disk again through “disk management” software in XP (Control panel, Admin. Tools), then try reloading everything. OS X-Tiger runs great otherwise, but I have yet begun to configure all components (being the PC guy virtually all my life, I am learning with the slow curve on MAC0. Will forward any positive results.

    I’m sorry but I can’t give any support for this one. The tutorial is how i got it to work, but why it isn’t working on an other machine is beyond my knowledge. The tutorial is “as is”.

    I install MAC.OS.X.10.4.6.X86-HOTISO and my PC screen is freeze on loading mac os x or STARTING MAC OS X . CPU is SSE2 compatible.

    Somebody get some idea?


  26. 15 years ago  

    OK so I went online first of all and read about how you could install Mac OS X in VMWare. My only problem is that the VMWare BIOS does not boot from the Mac OS X Tiger disk as a bootable source. It is an .iso image but it won’t boot from it. WHY? how do I get it to boot into setup? Or do I just need to copy the disk to the hard drive. If thats all I need to do then how do I create that crazy partition? And how do I copy into it without running Windows. I just want to install it on a VMWare hard drive.

    Come on guys, just buy a Mac. I tried the whole “Mac on a PC” thing two years ago. I gave up and bought a Mac. I now have two Mac minis and a MacBook Pro.

    what is the size of tiger-x86.tar.bz2? any one please

  29. 15 years ago  

    Hi, i have done to install the system on my pc,
    with 700 MHZ, 256 Ram. I have patched a cd in 2 days.
    If you do it alone, you succeed 100%.
    Don’s buy a mac when you can get a cd.
