But as the name implies, clean installing any OS will wipe your drive clean, meaning you will lose your files, photos and settings. So, before you even go ahead with it, it would be an immensely great idea to backup everything using iCloud or an external drive of any sort. As long as your data ends up in a safe and secure location, you're all good.

Also, make sure you have a fully compatible Mac with macOS Monterey before you go ahead with it. This is the list of supported Macs:

  • iMac (late 2015 and later)
  • iMac Pro (2017 and later)
  • MacBook Air (early 2015 and later)
  • MacBook Pro (early 2015 and later)
  • Mac Pro (late 2013 and later)
  • Mac mini (late 2014 and later)
  • MacBook (early 2016 and later)
