It's inside the 'Install Mac OS X Lion' app in the SharedSupport folder. It mounts as 'Mac OS X Install ESD'. Step 3: Mount the Base System image. The Lion installer image contains some hidden files, to get to them you'll need to use the terminal or in Pathfinder (which is easier for newbies) choose 'Show Invisible Files' from the View menu. Feb 17, 2012 Reading your previous post on page 2, I gather that you wish to install 10.7 on a unsupported macbook 1,1. If you are looking to install lion on an unsupported mac, then download 10.7 lion. The 64bit patch and kext have only been tested on macs that are running 10.7.3 build 11D50, and have the GMA X3100 GPU. No Mac OS after Lion will install on a MAC PRO 1,1 without editing the original install file. Apple places checks in the installer so that it will only work with certain motherboards. Part of the tweak to the installer involves adding your system's board ID to the installer so it will pass a check and install.
I know this is not a common scenario, but for the few people that upgraded a Mac originally equipped with a Core Duo processor to a Core 2 Duo processor, here is the procedure. I have an iMac version 4,1 that I upgraded years ago, and it worked. The person who found the solution had an upgraded Mac Mini. You will need a second computer that is Lion capable for this tip to work.
When the operation completes, boot your target unsupported Mac off the USB drive you just created by holding down the Option key while turning on the machine, and selecting the drive. Note: Only perform steps 5 and 6 if you intend to do a clean install. No Mac OS after Lion will install on a MAC PRO 1,1 without editing the original install file. Apple places checks in the installer so that it will only work with certain motherboards. Part of the tweak to the installer involves adding your system's board ID.
As always, Make sure you have a backup of the original install! This worked for me, but always be prepared for the worst. I made, and used, a Lion Mac OS X Install ESD on a thumb drive. Instructions to make one can be found all over the Mac centric web sites. Then follow this procedure:
- Put the unsupported Mac in Target Disk mode and plug it into a Lion supported Mac.
- Run the Lion installer and make sure to choose your unsupported Mac's hard drive. Let the install finish.
- Boot back into the supported Mac's OS, and put the unsupported Mac back to target disk mode.
- Delete the PlatformSupport.plist at /System/Library/CoreServices on the unsupported Mac's hard drive.
- Reboot the Unsupported Mac and it should boot into Lion normally.
