Mac OS X Lion (10.7) on my (upgraded) Late 2006 Mac Mini

After yesterday’s upgrade of my Late 2006 Mac Mini (MacMini1.1) it was time today to see if I could get OS X 10.7 (Lion) working on it. As perĀ  discussions on Apple’s discussion forms this should be possible (as the hardware supports after the upgrade I did). However, the standard OS X Lion installation did not want to install on this hardware yet. As per theĀ discussion on MacRumors.com I had to remove the file

/System/Library/CoreServices/PlatformSupport.plist

before the installation wanted to start. Once I did that, I could do a clean install on the new SSD Harddisk withougt any issues or additional hacks needed. Also transferring the users, apps and settings from the old system still on the external USB harddisk went fine and actually totally surprised me (I never used it before) as it turned the clean install in a totall usable system including the configuration of the OpenDirectory server.

After the installation it is important to enable Trim support on OS X to extend the lifetime of my SSD harddisk with the excellent tool Chameleon.

Right now I am very happy with the end result: a Late 2006 Mac Mini running OS X Lion (10.7):

Obviously only 3 Gb of memory is available as that is the max. the hardware supports, but still this is a very good solution to have a 2nd Mac Mini system for my children.
