i bought genuine apple os x lion off of ebay. it comes as a thumb drive. is that easy to use and install?
my neighbor gave me a macbook 4.1 a1181. it has os x 10.5.6 and wont undate any farther. i purchased os x 10.7 from ebay (genuine apple) and its on a thumb drive. is it easy to install and use? do i have to leave the drive in all the time for my OS to operate?
MacBook, Mac OS X (10.5.6)
