Hey gang - Just wanted to make sure it is safe to upgrade to 10.7.3 before I bite the bullet. There is always a possibility Apple may have added another "check" in Lion so these unsupported macs won't boot after installing a new update, and my computer is far too valuable for me right now (Schoolwork) to find out the hard way. My early '06 iMac is running 10.7.2 even though it is technically unsupported. It is upgraded to a Core 2 Duo (Originally a 2.0 Core Duo) and I removed the platformsupport.plist file so Lion would install. If someone has upgraded to 10.7.3 and removed the platformsupport.plist file with no ill effects, I'd like to hear about it! Thanks!
