Just a couple of weeks after releasing OS X Mavericks 10.9.3 to users, Apple has seeded the first beta of the upcoming OS X 10.9.4 to developers. We first reported that Apple was nearing a release of OS X 10.9.4 in beta to developers. It’s unclear what changes are in store with the new system, but hopefully it fixes the many headaches that Mac Pro users have been facing since 10.9.3’s release earlier this month. No word on when 10.9.4 will go public, but it is interesting that this Mavericks release will be in beta in tandem with OS X 10.10‘s beta release next week at WWDC. Thanks, D!
