Easily Install Mac OS X Leopard on an MBR Formatted Disk

Ugh, eff a GUID formatted disk! This is by far the easiest way to get OS X Leopard (Retail/Vanilla) to install on an MBR formatted disk. I’ve gone through about 400 other tutorials and most were so complex. This method, which consists of about 20 simple steps has worked like a charm so far. I suggest reading the tutorial, but it’s pretty much as easy as this:

Create a temp 6 gig partition. Then, in a Terminal window, run:

  • cp -R /System/Installation/Packages/* /Volumes/TempPart
  • cd /Volumes/TempPart
  • mkdir temp
  • mv OSInstall.mpkg temp/
  • cd temp
  • xar -x -f OSInstall.mpkg
  • cat Distribution | sed “s/eraseOptionAvailable=’true’//g” > Distribution2
  • mv Distribution2 Distribution
  • rm -Rf OSInstall.mpkg
  • xar -c -f OSInstall.mpkg *
  • mv OSInstall.mpkg ../
  • cd
  • rm -Rf temp
  • mount
  • cd /
  • umount /Volumes/TempPart
  • mount -t hfs /dev/diskXsX /System/Installation/Packages

Getting Windows 7 and OSX Leopard to dual-boot on a Hackintosh/Hackbook has not been easy. I’ll be posting how I did it once I’ve successfully booted into both.

    You aren't supposed to use it literally. It's likely disk0s3 but read the linked article to see exactly which one you'll be using.

    Hi,

    I see that you can directly "edit" the mpkg file, which is very impressive and cut down a lot of headache, however is it possible to edit the path it point to read the data?
    like in http://www.projectosx.com/forum/index.php?showtop
    I trying to get it work in Snow Leopard, will update if i get it done.

    Thanks !

    Hi

    I would also like it very much, if you could make this work on a Snow Leopard retail DVD.
