I apologize for adding to the number of similar questions, but I'm doing my searching and not finding any straight answers. I currently am on 10.9.5 and have been holding off on 10.10 for various issues reported here on the forums since its release. Can anyone whose done a recent upgrade from Mavericks give me obvious or noticeable issues with 10.10.3 you've experienced that you did not have on 10.9.5? I know of all the reasons why I should upgrade, but I don't want to pull the trigger just yet if things still haven't shaped up. I currently have no known issues on my late 2013 fully spec'd iMac running 10.9.5 and I don't want that to change.
