OS X El Capitan is the twelfth major release of OS X for Mac computers. It was released on September 30, 2015. Some users have reported an issue where Mac refuses to finish booting after updating to OS X EL Capitan. If your Mac will not start up, stalls on a gray screen with an Apple logo, here is how you troubleshoot. Using my MBP 16', I used the Download OS X El Capitan link on Apple's support site to get the installer. Unfortunately, running the InstallMacOSX.pkg package in the DMG failed: This version of OS X 10.11 cannot be installed on this computer. I 'found' a Install OS X El Capitan.app package and was able to create the bootable media.

Upgrade from previous versions to OS X 10.11 (El Capitan)

  1. From the Apple menu, select App Store....
  2. When the App Store opens, search for and download El Capitan. If you don't already have an Apple ID, you'll need to create one. You can monitor the download process in the 'Purchased' section of the App Store.
  3. Once the download is complete, the installer should automatically open.

    If it doesn't, or you don't want to complete the installation at this time, you can come back later and double-click Install OS X El Capitan in your Applications folder.

    Within the installer, click Continue, agree to the license agreement, and then choose the disk where you want to install El Capitan.

    After you begin the installation, your computer may need to restart more than once before finishing, and then you may be asked to enter basic information.

  4. From the Apple menu, select App Store..., and then install any available updates.

To reinstall or recover El Capitan, you must have an active internet connection. If you are on campus at IU, UITS recommends the wired Ethernet network instead of wireless. However, if IUSecure is your only option, see Connect to an IU wireless network in macOS if booted from your Recovery HD.
