John Olinda Hmmm... well uninstalled Homebrew to check out Yosemite, the visual changes are surprising to say the least.

Martijn I'm still on the fence. Is it worth the update? I am way too dependent on Mail and Calendar for Yosemite to mess them up.

Mark Dain Little Snitch has had quite a few updates but I think it's worth waiting for 10.10.1 although if you take a Time Machine backup, you can restore from that.

John Olinda Well, they seem to work fine except for two things. 1) The default mail handler somehow got changed to iTerm (what?) and 2) GPGMail isn't Yosemite compatible.
