Apple has released the fourth beta of OS X 10.10.3 to both developers and the public this morning, less than a week after the company seeded the third beta.
The new beta is pretty much identical to the third beta released last week, but adds a fix for the new MacBook Pro and MacBook Air that prevented it from working with those machines previously.
Previous betas of OS X 10.10.3 added a new single sheet of emoji, racially diverse emoji, and two factor authentication for Gmail. A preview build of the new Photos app is also included which will replace iPhotos and Aperture when the public release launches later this year.
Developers can grab the new OS X 10.10.3 beta from the Mac Dev Center, while public beta testers should be able to download it from the Mac App Store.
