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.

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.

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.

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?

Dev betas really shouldn't be installed on your main Mac. And they shouldn't be seen as a shortcut to fix any issues you've been having.

"Pre-release software, including Developer Previews, seeds, and betas, should be installed only on devices and systems that you have registered under your Apple Developer Program membership for development and testing. "

https://developer.apple.com/support/pre-release-software/

There really is no need to be afraid if you follow the guidelines.

Ahh, takes me back to the Windows OS bug fix release train.

You guys, as typical MR users, are incredible... If Apple don't release updates they are lazy, if they release frequent updates they are like Microsoft...
Haters gonna hate, no matter what....

hows el capitan on a 2011 MBP?

It run fine on my previously owned late 2011. Much better than Yosemite or Mavericks


By the way it is interesting to see how iOS and OS X are walking side by side lately. Release and most of the betas on the same day.
