Apple seeds first OS X 10.11.3 El Capitan beta to developers

Following today's iOS 9.2.1 beta release, Apple issued the first version of OS X 10.11.3 El Capitan to developers with minor improvements and bug fixes.

Aside from the usual stability, compatibility and security updates, the seed notes accompanying build 15D9c do not provide a detailed rundown of the exact changes included in today's OS X 10.11.3 beta release. A more detailed list, as well as focus areas for testing, should be included in the second beta release.

Apple's last update for the Mac operating system, OS X 10.11.2, dropped last week with a handful of improvements relating to Wi-Fi reliability, Handoff and AirDrop, Mail issues and iCloud Photo Sharing for Live Photos. The release also addressed a number of minor usability issues, bugs and security flaws.

The OS X 10.11.3 beta is the third seed to see release hit in as many months. Apple issued OS X 10.11.1 in late October, about one month after El Capitan debuted on Sept. 30.

Developers can download OS X 10.11.3 from the Mac App Store or Apple's developer portal.

While I have the impression that most users have had no problems with the .1 and .2 updates to El Capitan, many, like I, have had seemingly insurmountable problems, certainly of the incompatible software sort, such that the "updated" Macs won't even boot up. I hope .3 solves this.

Which software has given you trouble? But I'd see that as a software developers issue not the OS.

Mac mini late 2012 still endlessly plagued with problems since 10.11.1. No change with 10.11.2, other than the fact that now it is even less likely to boot into recovery than before. Sometimes comes up and goes great for a week, but if it crashes it will take a week of trying to even get it to boot. Endless chimes, no chime, crash at login crash during recovery, just awful. It ran flawlessly until 10.11.1, and if that is just a coincidence then several people have the same one in the support forums.. Live support has gone nowhere as it often won't stay up long enough for screen sharing or diagnostics.

I have a 2012 mac mini. runs great except the machine occasionally turns off after being asleep for a long time, usually over night. I will say that memory utilization on the machine is pretty high, has 16GB and usually sits at 99% used. On what Im not sure. VMWare fusion takes up a lot although I manage my VMs pretty well. Sometimes coming out of wake the machine can act a bit sluggish, and sometimes the USB keyboard will disconnect after being asleep and I have to unplug it and plug it back in. Small nagging problems but nothing service affecting.

Be very wary of ever assuming people with similar issues in support forums means anything. Not wanting to knock the good folks that try to help but you could state your Mac broke out in purple spots and you'd get a load of posts saying their's did too!

As always my first suggestion is get your hands on Disk Warrior v5 and see if you have damaged directories on the Mac. Disk Utilities is good but simply does not correct this problem. If you have another Mac you can run DW from that and mount the Mac mini using Target Mode. If not you'd need to boot to another disk as DW can only repair a dismounted drive. Believe me it is worth trying.

If you still have issues I'd back up and reinstall OS X from scratch and migrate the user folder back. If you still have issues it's something in you installed most likely.
