Following last week’s seed, Apple has provided beta build 13D45a of the upcoming OS X Mavericks 10.9.3 to registered developers. The update, as always, is present for developers in the Software Update tab of the Mac App Store. 10.9.3’s release date hasn’t been announced, but it includes improved iTunes syncing functionality and better support for 4K external Mac monitors.

  1. Does anyone know if this has helped with iMac sleep wake random shutdowns? I put my comp to sleep and then come into the office the next day and it’s been restarted. Gives me a sleep wake failure alert. Could be hardware but just curious.
