I just got off the phone with Apple support (who oddly enough were happy to help me, even though my warranty coverage expired ages ago). I have an old-school Macbook (the white one) from 2008. The build is 9L31a. According to Apple, my laptop is too "old" to run Mountain Lion should I choose to upgrade. I am currently running OS X 10.5.8 and I'm getting frustrated as I don't have access to iCloud or other application upgrades. According to support only the "late 2008" Macbooks (the aluminum-body ones) are qualified to upgrade. Specs are: processor is 2.4 GHz Intel Core 2 Duo, 2 GB memory with a 250 GB hard drive. I'm wondering... what would happen if I chose to upgrade anyway? Do you think it would work? Thanks!
