OS X 10.11.1 Beta 4

Apple has released the fourth beta version of OS X 10.11.1 El Capitan to Mac users participating in both the public beta and registered developer beta testing programs, arriving as build 15B38b.

Mac users running a current version of OS X 10.11.1 beta build can download beta 4 through the Software Update mechanism of the App Store.

If you were in the beta program before but have since opted out of seeing beta software updates, you would need to adjust that setting to find the latest version available again.

OS X 10.11.1 will likely focus on bug fixes and minor improvements to El Capitan, but new emoji characters, like a unicorn, burrito, and taco, also make an appearance in the release.

Any Mac user can choose to enroll in the public beta testing programs for OS X and iOS, but because beta system software is less reliable and more prone to bugs and crashes than a standard public release, it is only recommended for users who are comfortable with the less stable experience.

It’s unclear when the first point release update of El Capitan will arrive, but it’s likely that OS X 10.11.1 will be released to the public near or alongside iOS 9.1 when the iPad Pro and Apple TV are unveiled in the coming weeks.

    It seems to have corrupted 2 systems out of 3. Just be careful.
    One may be a bad crucial ssd that is several years old. But pretty sure the update scrambled my 17″

    I’ve encountered only two bugs in the official/10.11.0 release:

    * In Mail.app, I could only send from the @me version of my account (I typically use the @mac version). The solution wound up being logging out of iCloud (in the preferences pane, even though it showed me logged in under the @mac version) and then back in. It was a bit harrowing but everything was fine afterwards. YMMV.

    * I have a Lexmark CS510 series printer; since updating, I cannot use any of the printer’s specialty features — notably the envelope tray. If I try to, whatever app I’m printing from crashes. Lexmark has been no help (got a canned “check Lexmark.com for the latest drivers” response; the site hasn’t been updated since the release of 10.10, which they still refer to as “new!”).

    Otherwise, an uneventful upgrade.

      That’s Lexmark’s fault not to provide new drivers or apps that would work with new OS X releases. My own experience tells me to buy HP Printers instead.

    Why do you use beta releases if you don’t wanna deal with bugs? You guys make no sense. It’s a BETA (TESTING) release…of course there’s gonna be bugs. Switch to stable final releases and don’t complain.

    For me this has been one of the buggiest OS X releases and I’ve been using OS X since the first public beta

    Update lost all of my Email accounts, had to re-set them all :-<

    for ‘mail’ i didn’t get any notification about new incoming emails. i think its an problem with sort rules and “notification for all mailboxes”. hope apple will fix this soon.
