How to install iLife 09 on Mac OS X 10.5.5

iLife 09 requires Mac OS X 10.5.6

If you want to install it in 10.5.5, you need to change the SystemVersion.plist

sudo vi /System/Library/CoreServices/SystemVersion.plist

and change this

<key>ProductVersion</key>
<string>10.5.5</string>


to

<key>ProductVersion</key>
<string>10.5.6</string>


You cannot change the SystemVersion.plist back after installation, as iPhoto 09 and iMovie 09 will check this when launch.

If you want iPhoto 09 to skip the check*, you need to use a hex editor
open and change this file
/Applications/iPhoto.app/Contents/MacOS/iPhoto
then find (do multiple finds) and replace 10.5.6 to 10.5.5 and save it

*this trick does not work on iMovie 09
