Mac running slowly after macOS Ventura upgrade

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

Why did this happen?

Your computer 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 Ventura

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

• iMac (2017 and later)
• iMac Pro (2017)
• Mac mini (2018 and later)
• Mac Pro (2019 and later)
• MacBook Air (2018 and later)
• MacBook (2017)
• MacBook Pro (2017 and later)
• Mac Studio (2022)

If you do not see your Mac device from the list above, you will either have to put up with its sluggish performance or roll your system back to Monterey.

Check if your Mac is reindexing

Check to see if your Mac is operating faster when reindexing is complete.

1. Select the Spotlight icon in the Menu bar.
   A progress bar in the window indicates that it is reindexing.
2. Allow it some time to complete.

Check if your Mac has enough disk space

Your Mac needs to have at least 25 GB of free disk space to run macOS Ventura:

1. Go to Apple menu > About this Mac.
2. Click the Storage tab.
3. Click Manage... to see detailed lists of what is taking up storage and where it is located on your Mac.
4. Delete files or apps you do not need to free up some space.
5. Empty the Trash.

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
