Also, I would like to point out (again) that if you are running Adobe's Creative Suite 6 and below, Mavericks has compatibility issues with some programs for some users. Ex: Photoshop's 'save as' doesn't work, and stuff like that. If your business is dependent on any of these softwares like in my case, I suggest you wait for a few months before these bugs are squished (which Apple of course is pretty good at).
Cheers.
