Apple Seeds Second OS X 10.11.3 El Capitan Beta to Developers and Public Beta Testers

Apple today seeded the second beta of an upcoming OS X 10.11.3 El Capitan update to developers and public beta testers for testing purposes, three weeks after seeding the first OS X 10.11.3 beta and a month after releasing OS X 10.11.2.

The second OS X 10.11.3 beta, build 15D13b, can be downloaded through the Apple Developer Center or via the Software Update Mechanism in the Mac App Store for those who installed the first beta.

os_x_el_capitan_roundup
The first beta of OS X 10.11.3 did not include any noticeable outward-facing changes, suggesting the update will focus on security enhancements, performance improvements, and bug fixes to address issues that have been discovered since the release of OS X 10.11.2. Prior OS X El Capitan updates have also focused mainly on under-the-hood improvements.

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

Great series, especially with an SSD and 8 Gb of ram installed

I never see the loading bar in the indexing box, but that's the least of my worries. Apple ignored my reports about MAIL corruption, Bluetooth crashes that required shutting the machine down. So what did Apple do in response to my constant complaints. My Apple ID no longer works correctly. Sure, I file reports but they fall on deaf ears. No response. AND, publicly as announced here, they renounced any support for Mac models including mine that are in the system list for Macs certified to run El Capitan! If that's not lame I don't know what is.
It looks like I'm going to have to do another complete reinstall again from Mavericks.

THANK YOU MAVERICKS! Without lowly Mavericks, I would have probably lost THOUSANDS of important emails.

This update has solved nothing about my Mac not be certified with my Apple ID either nor does it fix any mail problems.

Looks like I'll start from scratch all over again. Apple has really let Mac OS go. It's sad really. And worse yet, they don't seem to care. :-(
If your mails are so valuable then I strongly suggest you not to use betas....

That's pretty quick, so you must have approximately 65Mbps internet speeds?
I think people only say how long it took to download so they can boast about their connection speeds.

As the afternoon has worn on, I've watched emails disappear from Mail, then re-appear within a couple of minutes, so this didn't fix the problem. Even on the non-beta, I was having this problem and can say that both of the recent beta updates seemed to improve the situation, but it's still a problem - unfortunately.

Please reduce the beach balls and apps that don't seem to load. Messages just bounces in the dock until I force quit and reload, even after a fresh install.

I miss Yosemite.

This to me means that the changes are just too embarrassing to list.
I had the same thought but I try to be more optimistic (which is very hard given the number of bugs in 10.11.2).

Probably it's a placebo update, will be released for the sake of releasing but not fixing any longstanding issues...
I'm afraid that is going to happen. At this rate I'm fairly certain it will take at least 10.11.4 or .5 before Apple fixes Time Machine failure to restore files that I reported during beta testing... :mad:

I just hope some good changes are made for disk utility
One can hope but I'm fairly certain hell will freeze over before that happens... :(

I had a similar situation and I didn't lost any emails because I tested 10.11 on external drive and stopped using it moment I noticed the Mail problem.

I'm going to stay in Mavericks for the foreseeable future because 10.10 and 10.11 have no benefits for me and both contain too many bugs and baffling design decisions.

It seems certain Apple no longer cares about OS X. :mad:
