Install OS X Lion on a Mac mini I borrowed a Core 2 Duo Mac mini. I want to back up the HDD and wipe off the OS Leopard that it has so that I can later re-install it back. Then I want to upgrade to OS X Lion. Can this Mac mini run Lion? What steps should I take?
specs here:
mac mini 3.1
Intel core 2 duo 2.26ghz
4gb ram
1GB of RAM is insufficient for OS X 10.7 "Lion."  You'll need 2GB or more.:
