OS X El Capitan LogoApple today seeded the second beta of an upcoming OS X 10.11.5 El Capitan update to developers for testing purposes, two weeks after releasing the first OS X 10.11.5 beta and a month after releasing OS X 10.11.4, the fourth update to the OS X 10.11 operating system.

The new OS X 10.11.5 update, build 15F24b, can be downloaded through the software update mechanism in the Mac App Store or through the Apple Developer Center.

Like prior OS X El Capitan updates, the fifth update is likely to focus on security enhancements, performance improvements, and bug fixes to address issues that have been discovered since the release of OS X 10.11.4. No obvious outward-facing changes were found in the first OS X 10.11.5 beta, but we will update this post with any changes discovered in the second beta.

Why does the 9.3.2 beta 2 release make the front page and this is stuck in the Mac Blog? MacRumors should be renamed iOSRumors :rolleyes:

Evidently we can't please everyone. We've started putting some of these release posts on the blogs after receiving complaints that we were putting everything on the front page. :)

We'd be happy to stick them on the front page if we were seeing more changes in them, but 10.11.5 seems to be a pretty invisible update unless there are some changes I've missed seeing.

To be fair it's not MacRumors fault. It's Apple's fault for getting lamer and more mediocre by the minute.

Anyone else have wifi connectivity issues with the previous beta?
Now that you mention it, I did notice a few times that when email was being checked immediately after 'wake-up" it would complain about 'not connected to internet'. So I would wait for around 15 seconds while the iMac sorted itself out.

I'm still waiting for (assume its not an option already) the ability to setup messages to delete after 30 days. I have and use this feature on my iPhone and iPad but its manual on my 2 MAC's. Not a huge deal, nothing there someone can't see, but don't need to keep messages around forever so I have them remove themselves.
