Hi all, Stupid question probably, but I'd like to know if my iMac will be able to run Lion, should I choose to upgrade. I have a late 2007 Al iMac, 2.4GHz Intel Core 2 Duo, 500GB HD, 4GB RAM. SL runs fine and I'm of the opinion that, "If it ain't broke don't fix it". Still I'm wondering. Will 10.7 Lion run okay on this iMac? Thanks to all!
