How to downgrade macOS Sierra with Time Machine
Before we get started, it's important to remember that for this tutorial you need to have created a restore point - also called Time Machine Backup - on an external drive when your computer was still using the El Capitan version. This can also be done with earlier systems like Yosemite or Mavericks. Another recommendation is to back up the current files on your computer, also to an external drive.
Note: Restore points return the computer to the state it was in at the time it was created. That is, everything that was downloaded or installed on the computer after that time is deleted. Remember to save these files to other storage systems, be it on a USB stick, external hard drive or cloud storage services like iCloud or Dropbox.
