Remember, this method is not the same as a clean install, and it only reinstalls the version of OS X that is currently running on the Mac (shown here with El Capitan), whereas Internet Recovery will reinstall the version of OS X that shipped with the Mac (in this case it would have been Yosemite) instead. Obviously the versions of OS X will. Once you’ve done that, here’s how to install, reinstall, or upgrade to El Capitan, step by step: Boot from your Recovery HD partition by restarting your Mac while holding down the Command+R keys. The OS X Utilities window appears. Select Reinstall OS X, and click Continue. The OS X El Capitan splash screen appears. OS X El Capitan won't install on these two MacBook Pros (8,1).

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.

Reinstall Os X El Capitan From Usb

Although Apple is about to release the next version of the newly renamed macOS in the coming days/weeks, I expect this posting will be useful not only for OS X El Capitan or Yosemite, but also likely for the next version of macOS Sierra (10.12).

Why Can't I Reinstall Os X El Capitan

If you are already running OS X El Capitan (10.11) and need to reinstall the OS or install a fresh installation to a new hard drive (or partition), you may find as I did that downloading the OS X El Capitan (10.11) from the Mac App Store is simply not working. What I experienced after clicking the Download button was a busy indicator spinning indefinitely and the download never happening. I tried this on several different Macs with the same result. Of course, all my Macs were already running OS X El Capitan (10.11) so my attempts failed consistently on all three.

After contacting Apple Support, my first call ever by the way, apparently Apple now only allows each Mac to download the OS X El Capitan/Yosemite installation file one time per machine. This is what I was told by Apple Support. Also, when looking at my Purchased apps in the Mac App Store the OS X El Capitan did not allow me to download it and showed disabled “Downloaded” button instead, even though the OS install file already on my Mac was unusable. Delete this file had no affect on the ability to re-download the OS installation file.

However, Apple Support instructed me how to accomplish this another way – a legal and supported option. And that is by booting your Mac into Recovery Mode (or OS X Utilities) menu. Here are the steps.

1. Reboot your Mac and enter Recovery Mode by pressing Cmd-R during the boot up sequence. You need to hold down the Cmd-R keys until the Apple logo appears. It can take several minutes before the Recovery Mode menu finally appears, so be patient.
2. Select the Reinstall OS X option and click Continue.
3. You will be given the option to select the target drive where the new OS will be installed. For me, I had two drives and wanted to install it on a newly attached SSD drive. Also, depending on the your computer you may need to select and connect to WiFi.
4. A new copy of OS X (macOS) will be downloaded and the installation will begin.
