OS X El Capitan Public Beta 1 Available to Download & Install for Mac Users

Jul 9, 2015 - 39 Comments

OS X El Capitan Public Beta

Apple has released the first public beta version of OS X El Capitan (10.11). Any Mac user with an Apple ID and compatible Mac can choose to download and install the public beta, though due to the nature of beta system software, this is generally only recommended for advanced users.


Interested users have multiple options for running OS X El Capitan Public Beta. The best choice for a single Mac would be to back up the Mac as usual with Time Machine, then install OS X El Capitan onto a separate partition, this maintains the primary stable OS X partition and installation and allows for a dual boot environment. Users can update existing OS X versions to the Public Beta of El Capitan, but that is not advised. Finally, users can also just run OS X El Capitan Public Beta on a separate non-primary Mac, if one is available.

Downloading & Installing OS X 10.11 El Capitan Public Beta 1

  1. Go here and register to enroll in and participate in the OS X El Capitan Public Beta program
  2. Start a back up with Time Machine and let it complete
  3. Download the OS X El Capitan Public Beta from the Apple website, the download goes through the Mac App Store as usual

Be advised that the download may take a while to complete as Apple servers are busy with the initial rush of interest.

Downloading OS X El Capitan Public Beta

Once the installer has downloaded into the /Applications/ folder, you can choose to create a bootable installer drive of the OS X El Capitan beta with any USB device if desired, this must be done before the application installer has run, as it deletes itself automatically when finished. You can also just run the application immediately if desired.

As already mentioned, it is advised to run OS X EL Capitan beta on a secondary Mac, or run it on a separate partition and dual boot the Mac with a stable OS X release. Early beta system software is notoriously buggy and can behave strangely, thus it is not intended for prime time use.

OS X EL CAPITAN 10.11

If you decide to run the OS X El Capitan Public Beta, you will want to file bug reports and issues as they are seen, this is easily done through the built-in Feedback Assistant application that comes with the beta installation. This can help to shape the future of OS X, and to inform Apple of bugs, issues, or other things which may need to be addressed before the public release this fall.

Separately, users can choose to participate in the freshly available iOS 9 public beta.

    You can create a bootable USB drive with the OS X EL Capitan Public Beta by using the following command:

    sudo /Applications/Install\ OS\ X\ El\ Capitan\ Public\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/ElCapInstaller --applicationpath /Applications/Install\ OS\ X\ El\ Capitan\ Public\ Beta.app --nointeraction

    This assumes the installer is in the /Applications/ folder, and that the target USB volume is named “ElCapInstaller”

    I am downloading the public beta, but I am not seeing it in my applications folder. Does it not appear until the download is complete? Thanks

  3. mojoron says:

    With the problems I have with iPhoto and Photos and the glitchy Mail, why would I want to ask for more problems with a Beta?

    • paul says:

      The public beta is for users who are wanting to test the beta system software, it is not intended for widespread usage by most Mac users.

  4. mojoron says:

    And….Safari

  5. mojoron says:

    Plus I don’t want Apple Music!!!!!!!!!!

  6. Morty says:

    I enlisted, got my redeem code, started downloading,..

    then we got internet connection issues, and i had to close down my macbook for a while

    Now when internet is back up and running, and macbook connected to power – I am unable to find any way to resume/restart the download.

    the redeem code is already registered as used,
    and the Appstore has not registered any “purchase” I can resume,

    Anyone have any good ideas of How I can get this big download/upgrade restarted?

    • j says:

      Go to the App Store and the Store menu, choose ‘Look for unfinished downloads’, it should display with that. Otherwise if you have already downloaded the El Capitan Public Beta installer, it will be in the Purchases tab or the /Applications/ folder of OS X

  7. Robert says:

    Did anyone else have Feedback Assistant not download?

  8. Juan says:

    I keep getting an error message when I try to use a web browser on the beta… Is anyone having this issue too? Can someone help?

    • BUzz Kill says:

      Both my mail & safari keep crashing. Now my feedback assistant keeps crashing. I recommend people wait till the next seed before installing.

    Do anybody try it yet?

    Are Apple fix the choppy resizing of the windows?

    Some change in the maximize behavior?

  10. TonyM says:

    I had exactly the same web browser problem with the El Cap beta, so I have gone back to Yosemite for the time being. Think I’ll wait until the bugs have been ironed out.

  11. Kro says:

    The same people that whined because of Yosemite problems are now jumping onto the beta.

    Why don’t you enjoy the now stable Yosemite for a second.

  12. AlexJ says:

    Anyone having trouble with the window snap feature? I can’t seem to get it working on my mac, this has happened not only on the public beta but also when using the developer previews

    • AlexJ says:

      I got it working, it turns out that you have to uncheck “Group windows by application” on the Mission Control pref pane. :)

  13. John Merrill says:

    I’ve installed the beta on an external drive. However I am a general user and can’t alter the Application folder or change startup discs because I can’t find a way to login as Admin. (I shutdown and unmounted the external HD to get back to my main drive.)

    Any ideas?I’ve tried all possible user names/password combos.

    • iht says:

      Create a new admin account under users control panel and use that login

      • David says:

        You can’t create a user unless you have administrator privileges, but the installer made the default account a non-administrative account. So I’m stuck (as is the OP)!

  14. Ed says:

    Beta is very fast on my retina iMac but I lost 1 of my 2 external thunderbolt lcd’s.

  15. Mike says:

    I’ve installed the public beta El Cap and I can launch the App Store but nothing loads. Anyone else having this issue?

  16. brad says:

    When looking in my app store purchases for el capital it is telling me that it is waiting. Am I to assume that it is waiting to download and there is nothing further for me to do except wait?

  17. NWProf says:

    In reading the article, as well as the comments here, I did not see the answer to a question I have, so I’ll just ask. Can you download a fresh copy of El Cap (or Yosemite) from Apple to a blank, formatted hard drive, or, must you have a previous copy of OS 10.9 or 10.10 already on the HD?

  18. Hugo says:

    When I tried to download the el capital public beta it just stopped at 1.6gb of 6gb and when i clicked the download icon in launchpad it just disappeared. Now, when i try to download it again, it says i already used that code in the App Store. So now i can’t download it… Someone know what you can do??
    :)

  19. Paulo says:

    in my case the result is an error: “Mount of outer dmg failed”. How can i fix it?

    Running El Capitan Beta on Retina MBP 13″. Only bug is recovery boot screen flashes a bit. Other than that, using it on a primary mac, great experience.

  21. Craften says:

    Early benchmarks show that current versions of OS X El Capitan perform the same or worse than OS X Yosemite, see for yourself:

    http://www.tonymacx86.com/el-capitan-desktop-support/168046-benchmark-el-capitan-public-beta-vs-yosemite-10-10-4-a.html

    So while OS X El Capitan is hopefully more stable, don’t expect the performance boost that many users have been hoping for. For that, you’d need to upgrade to OS X Mavericks if your Mac will support it, which at this point, is anything early 2014 or older. Ironic!
