First OS X El Capitan 10.11.3 Beta Debuts to Devs

Following today’s iOS 9.2.1 beta, Apple has seeded developers with OS X El Capitan 10.11.3. The update is available to developers only at the time of writing this post via the “Updates” tab in the Mac App Store.

Last week’s update, OS X 10.11.2, which was released to the general public, brought lots of improvements to the overall OS including graphics, Mail, Wi-Fi, Calendar, USB, Notes, Photos, Spotlight, and networking, while 10.11.3 beta 1 seems to focus mainly on bug fixes and speed improvements as there are no release notes published alongside this beta.  But this could change, as there will most likely be like 4 or more builds before Apple decides to release the update to the general public.


We’ll update this post if we find any major or outward facing changes. Let us know if you notice anything different in the new build with a comment below!
