After seeding the third beta for iOS 7 to developers yesterday.. Today Apple has just released OS X Mavericks developer preview 3 to developers and it is available at the Mac App store..The update, which comes in at just a hair over a gig, touches down two weeks after the second developer preview.
I’ve already installed DP3 on my test partition, and I haven’t noticed any drastic changes thus far in my usage with it. Check out the release notes inside…
