- The process in El Capitan is (compared with root-canal work, income taxes, or previous versions of OS X) relatively painless. How to install (or reinstall) OS X. In theory, you should have to install El Capitan only once, or never if your Mac came with El Capitan preinstalled. And in a perfect world, that would be the case.

- Markverhyden said: The Apple ID is the issue. If the machine was registered to an Apple ID, which is% certain, AND they have Find My Mac turned on and they have 2FA then it will not work without that PIN code. As mentioned elsewhere Apple's 2FA is horrible.

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).
How To Download 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.
Reinstall Os X El Capitan Error
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.
How To Install El Capitan
- 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.
- Select the Reinstall OS X option and click Continue.
- 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.
- A new copy of OS X (macOS) will be downloaded and the installation will begin.
