I'm trying to reinstall Mac OS X El Capitan on a new Macbook Air. Disk Utility lists a single SSD with a capacity of 251GB and a single partition (OS X Base system) that is taking up 250.4GB. When I try to create another partition it says that I need to enable journaling, but the option is greyed out. If your Mac is a 2011 or later you can use Internet Recovery (command-option-r) to erase the hard drive and reinstall the original OS then upgrade to High Sierra from there. If you insist on using El Capitan you will need to sign into the App Store on a Mac that cannot run High Sierra and download EL Cap, then make a bootable usb installer to use on your MBP.

Reinstalling mac os x el capitan but temporarily unavailable
  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.
