I made a the biggest mistake of my Mac life when I took the Yosemite bait when using Mavericks. It has ruined my MacBook and now I'm trying to find a way to get rid of it and perhaps Mac altogether. No one said anything about the danger of loading Yosemite in a 2009 MacBook and I've had nothing but grief since as I spend my days waiting, waiting for the computer to do one thing, let alone a few things. And the perpetual spinning ball. How I hate that thing! And the most unforgivable thing Mac has done: it won't allow you to go back. You are forced to like it or lump and so I have to get rid of my MacBook and some other poor soul will have to live with it too.My question is, how can I rid myself of the bane of my life, a mid-2009 MacBook with Yosemite system?
