You notice your Mac is running slower than usual after installing macOS Monterey.

Why did this happen?

Your system might have performance issues because some apps are still being optimized for the new macOS.

What should I do next?

  • Check if your Mac is compatible with macOS Monterey:

    Listed below are devices that can run the new operating system:

    • MacBook, early 2016 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
    • iMac, late 2015 and later
    • iMac Pro, 2017 and later
  • Check if you have enough disk space:

    Your Mac needs to have at least 20 GB of free disk space to run macOS Monterey:

    1. Go to Apple menu > About this Mac.
    2. Click the Storage tab.
  • End unnecessary apps and background tasks:

    Use Activity Monitor to see which apps are using up Mac resources:

    1. Go to Applications > Utilities.
    2. Double-click Activity Monitor.
    3. Under the CPU tab, sort the list by %CPU to see which apps uses the most resources.
    4. Select the app you want to end, then click the button at the top.
  • Close unneeded tabs and windows:

    If you have a lot of browser tabs open, it also cause performance issues for your Mac. Check if you do not need some of the tabs open or you can also restart your Mac for it to refresh the applications.
