Apple Seeds First OS X 10.11.3 El Capitan Beta to Developers

Apple today seeded the first beta of an upcoming OS X 10.11.3 El Capitan update to developers for testing purposes, just over one week after releasing the second OS X El Capitan update, OS X 10.11.2. OS X 10.11.2 was a minor update that introduced several bug fixes and performance improvements for Wi-Fi connectivity, Handoff, and Airdrop.

The new OS X 10.11.3 beta, build 15D9c, can be downloaded through the Apple Developer Center.

It is not known what improvements the third update to OS X El Capitan will bring, but like prior updates, it's likely to focus on security enhancements, performance improvements, and bug fixes to address issues have been discovered since the release of OS X 10.11.2.

We'll update this post with any changes that are discovered in the beta.

They must have outsourced Mail and Preview dev to India. They just can't seem to get it right.
As if people could only write a bad code in India and not elsewhere...Get a life.

Fix Preview which is been broken since the initial release. PDF still render pixelated especially if you resize the window, and it still uses ridiculous amounts of RAM.

After the series of usb beta problems with 10.11.2 betas, I am afraid of Apple betas. I used to be first on board with these but they seem to be pushing more and more experimental changes under the hood that are not readily apparent. I wonder what's up with this series....

On another matter, how do they coordinate all of these betas for ios and osx to now always come out about the same day? Do they give each team the same deadline . . ready or not .. go?
