I have a 2010 MacBook Pro currently running OS 10.8 . I would like to upgrade, but I need to know if I can install (and run) my iDVD from my iLife install disc. I want to restore to original settings to clean things up, but I'm afraid I'll lose my iDVD. I'm also not clear on the sequence. Would I upgrade to Yosemite first, then restore to original, or the other way around. If I go to the Apple store and have them clean the hard drive, they will install from the latest OS I imagine, which will not have iDVD on it. Any suggestions? Thanks.
