So I'm considering updating to Yosemite, but I have a 2011, low end MBP, and Im a bit afraid that its going to be slow. If I do upgrade, is there anyway that I can revert back to mavericks? I've seen a bunch of things online, but that was only for the developer previews, which rely on the Mavericks installer still being on the app store, which I don't think it is.
Thanks.
