My guess is this question has been asked and answered many times, but a quick search, did not reveal it. I decided to upgrade my MBP to Mountain Lion from Snow Leopard. I launched the App store, bought ML, and now on the App Store Page, it says downloading, but I'm getting no progress info. Edit: Found that under purchases... Questions: Where is the download file kept? I've read that it goes to home>Library>Application Support> App Store. I looked in there and while I see something in there that might be it, it is not clearly marked. If I turn off my computer, will the download pickup where it left off or start over again? After download and install, will this file remain or be auto deleted? If deleted, is there a way to save the file somewhere else? Will it auto launch and try to or offer to install? I assume on the App Store page, the button will say install. Does this upgrade require anything to be done with my Bootcamp Partition or should that remain uneffected? Thanks!
