Apple today seeded the fourth beta of an upcoming OS X 10.11.6 El Capitan update to developers and public beta testers for testing purposes, one week after releasing the third OS X 10.11.6 beta and more than a month since the public release of OS X 10.11.5. OS X 10.11.6 has been in testing since May 23.

The fourth OS X 10.11.6 beta update can be downloaded through the Apple Developer Center or the Software Update mechanism in the Mac App Store.

OS X 10.11.6, much like OS X 10.11.5 and the El Capitan updates that came before it, focuses mainly on performance improvements and bug fixes instead of obvious outward-facing changes. According to Apple's release notes for earlier betas, the update improves the stability, compatibility, and security of Macs.

No obvious changes or bug fixes were found in the first three betas, but we'll update this post should anything new be discovered in the fourth beta.

Apple has also started testing macOS Sierra, the next-generation Mac operating system set to be released this fall. macOS Sierra includes features like Siri integration, auto unlocking with the Apple Watch, Apple Pay for the web, a new storage optimization feature, and more.

kk. we ready for sierra PB! :apple::apple::apple::apple::apple::apple::apple:
Not until July as was said in the keynote. It has usually happened not long after the release of DP 3.
[doublepost=1467221344][/doublepost]Looks like MacRumors is still suppressing Mac news into the Mac Blog while watch band shortages make the front page. Seriously MacRumors, get your priorities straight. I'm tired of this.

The more versions Apple adds to El Capitan, the better. I can't see myself updating to Sierra right after it's getting released, maybe after 2 or 3 months.

Are USB devices finally working normally?

It has been problematic since 10.11.0 and there is no way I'm going to install 10.11 unless it is fixed permanently. All devices work normally in Mavericks so it has to be 10.11 driver issue.

I'm also hoping Apple would fix other bugs such as Spotlight can't find files (reindex helps for a few days), Finder, Photos opening instead of Image Capture etc. Sure I can work around these bugs but why bother because they don't exist in Mavericks?

I have reported all of these to Apple after every point release to 10.11 was released and I'm not exactly impressed that none of the bugs have been fixed! :mad:
