Sorry if this has been answered elsewhere, but I can't seem to find an answer. I upgraded to the public beta and really don't like it. Clicking Finder doesn't open a new Finder window (reported by many others as well) and the new Photos app really messed up the dates of a lot of my photos. How would I revert back to 10.10.2? I have a Time Machine backup of 10.10.2 from about a week ago, which I would be okay with going back to. Is it as simple as just restoring from that Time Machine backup?
