Apple Seeds Second OS X 10.11.6 El Capitan Beta to Developers

by

Apple today seeded the second beta of an upcoming OS X 10.11.6 El Capitan update to developers for testing purposes, two weeks after releasing the first OS X 10.11.6 beta and three weeks after the public release of OS X 10.11.5.

The OS X 10.11.6 update, build 15G12a, can be downloaded through the Apple Developer Center or the Software Update mechanism in the Mac App Store.

OS X 10.11.6, like OS X 10.11.5 and the El Capitan updates that came before it, appears to focus mainly on performance improvements and bug fixes. According to Apple's release notes for the first beta, OS X 10.11.6 improves the stability, compatibility, and security of Macs.

No outward-facing bug fixes or changes were found in the first beta but we'll update this post if any new features are discovered in the second beta.

My sense is iOS, OSx, WatchOS, TvOS updates are in part, being rewritten in Swift. New Xcode development tools and improvement in Swift itself are part of Apple's development efforts going forward.

If my suggestion is true, this is a big deal -- a really big deal with the potential of exponential improvements in functionality, stability and cross-OS support.

That doesn't specify anything. Those are minors.
Ah, so you like an OS full of bugs. Got it.

Highly unlikely. There's no incitament for Apple for rewriting those things in Swift, as it is still a language under strong development.

El Capitan keeps getting updated, but there are at least 3 major bugs, two of them VERY major (and have been reported by several users here independently) that I've reported and confirmed with Apple, but they've not been fixed.

So if these updates have zero user-facing changes and don't fix the showstopping stuff, what are they for? Is it to give the illusion that Apple is focusing their attention and resources on OS X? Because based on the last few years, I really doubt it.

For 2016 MacBooks, it resolves the issue in the original 10.11.6 build where certain USB 3.1 devices would not mount. It was an issue in the 10.11.5 beta, fixed in the final 10.11.5 build, but reverted in the 10.11.6 original beta.

Well yeah.. Nothing is perfect but I mean was there something huge that occurred with .5 that they needed to address? Or is this just another maintenance?
I'm guessing security and maintenance.

Plus, it looks like it's going to line-up with WWDC, so maybe something is hidden in there.
