Running OSX 10.7 Lion on 32-Bit Mac Mini (2006)

Bypassing Compatibility Checks on 32-Bit Intel Macs

The 2006 Mac Mini with a Core Solo or Core Duo (32-bit) is officially capped at Snow Leopard. Booting the 10.7 Lion Developer Preview requires a 64-bit CPU 'spoof'.

The Solution:

  1. CPU Upgrade: The best fix is to swap the T2300/T2400 for a Core 2 Duo T7200 or T7600. This gives you native 64-bit support.
  2. The Hack: If you must stay on 32-bit, you need to modify the OSInstall.mpkg and Distribution files inside the installer to remove the hw.model and cpu-type checks.
  3. PlatformSupport: In the early 10.7 previews, the check was often embedded in the boot.efi itself.

Original Question: "OSX 10.7 on Mac Mini 2006 with a 32-Bit CPU"

Has anyone booted the first Developer Preview of 10.7? I got the installer booted but it says that my Mac isnt compatible, the limit must be in the pkgs, bc theres no PlatformSupport.plist anywhere. If anyone has a while to help me i would be super thankful.
