Mac OS X 10.7 Lion running on a Core Duo Mac

Many owners of the oldest 32-fleck Intel Macs were discouraged when they institute that Mac Bone 10 Lion'southward organisation requirements demanded a 64-fleck Cadre two Duo processor or newer. These users were discouraged, but non deterred, considering some have managed to go the latest Lion developer build running on older Core Duo Macs… sort of.

Outset some background. In earlier developer previews, running Bone X Lion on a Core Duo Mac was just a matter of deleting a plist file and then it would magically kicking. Elementary plenty. That changed in afterward dev previews, and in Dev Preview iv things get a flake trickier. Now onto the electric current land of affairs…

The Bad News
This isn't really a usable solution still, because Finder.app doesn't run (it's a 64 fleck awarding, therefore won't run on 32 scrap hardware) and launchd consumes also many system resources.

The Good and/or Optimistic News
Lion DP4 is booting on these 32-bit Macs! This means that subsequently the public release in July we will almost certainly see a modified Lion kernel and Finder that runs as expected on the oldest Intel Macs. This is much less of a stretch than some of the other crazy Mac Bone X installations out in that location (remember all those Hackintosh machines running on Cantlet, Pentium 4's, AMD CPU'southward and other unsupported hardware?).

OK and so enough blabbering, let's get over the process that works right now to kick Lion on ye erstwhile Intel Macs.

Getting Lion DP4 to Boot & Run on a Core Duo Mac

Of import: This is non supported by Apple or anyone else, and in the electric current land Lion is not usable on 32-bit Macs. This is provided for informational purposes only and nosotros are not responsible for your screwing upwardly anything. Always backup your Macs. Proceed at your ain risk.

This procedure is not for the faint of centre, and it isn't the simplest process in the earth. You'll exist editing and moving around some system files and you lot'll need access to the post-obit:

The 32 bit Mac in addition to a 64 bit Mac to install King of beasts DP4 onto
Lion Programmer Preview 1 – build 11a390 – this was the last dev preview that had 32 bit kernel support
Lion Developer Preview iv – build 11a480b
External difficult bulldoze or hardware knowledge – this isn't entirely required but it makes it easier because you will be swapping the modified Panthera leo DP4 installation from a 64 fleck machine onto the 32 bit Mac
Patience, decision, and a desire to tinker

Have all that ready? Here are the steps taken to run King of beasts on a Core Duo Mac:

Install Mac Bone X Lion on a compatible Mac (pregnant 64 flake)
Delete the PlatformSupport.plist file located at:

/System/Library/CoreServices/PlatformSupport.plist

Anoint kicking.efi from Panthera leo Developer Preview 1

bless --folder "/Volumes/Mac OS X/System/Library/CoreServices" --bootinfo --bootefi

Replace the Lion DP4 kernel with the kernel from DP1, mach_kernel.ctfsys or mach_kernel is located in your root directory at /
Replace the following Lion DP4 files with the versions from Lion DP1, they are located in /Systems/Library/Extensions/ :

AppleIntelCPUPowerManagement.kext
AppleIntelCPUPowerManagementClient.kext
AppleIntelIntegratedFramebuffer.kext

Transfer this modified Lion DP4 installation to the Core Duo Mac and kicking it

The 32-bit Mac will kicking into Mac OS X Lion, just now come the problems: Finder doesn't run at all considering information technology's built as a 64 fleck awarding, and launchd will eat up the majority of your resources (this may or may not be related to the dull King of beasts boot and usage issues that resolve themselves). Resolving these issues could be a matter of just grabbing Finder.app and launchd resources from DP1 and moving them to DP4 too, we'll see.

Looking Forward, Theoretically At Least
A month or two from now, you may exist able to buy Lion on a 64-bit Mac, re-create the system folders, throw in a modified kext file or two, then boot and utilize King of beasts as usual on an unsupported 32-bit Mac. This obviously wouldn't be supported by Apple, but it could exist acceptable use because of Lion'southward generous personal license that allows you to install the OS on all of your personal Macs. That last part we won't know until we see the terminal King of beasts EULA, but it'due south not too far fetched.
