CleanMyMac X on macOS Catalina

The up-to-date version of CleanMyMac X fully supports macOS 10.15 Catalina but requires a bit of your attention. The new macOS includes critical changes in the privacy control, that’s why now apps like CleanMyMac ask for some special permissions to run smoothly. For example, permissions are needed to uninstall apps correctly or find more junk across the system.

According to Apple’s new rules, you need to provide these permissions manually in macOS System Preferences. The configuration takes less than a few minutes, so please follow the instructions below to allow CleanMyMac operate at full capacity.

Update CleanMyMac X

Make sure you have CleanMyMac X 4.0.3 or higher:

  1. Open CleanMyMac and click the CleanMyMac X in the upper left corner of the screen.
  2. Click About CleanMyMac and look at the version below the CleanMyMac icon.

If your version of CleanMyMac X is lower than 4.0.3, go to CleanMyMac X → Check for Updates and install the latest available version.

Grant permissions on macOS Catalina

First, open your System Preferences:

  1. Go to Applications → System Preferences.
  2. Open Security & Privacy and switch to the Privacy tab.
  3. Click on the lock in the lower left corner and enter your password.

Now, give CleanMyMac access to the permissions listed below.

Full Disk Access

Giving the Full Disk Access permission is enough to let CleanMyMac function properly. So if you did, you can skip adding it Photos, Calendar, and Contacts permission lists.

CleanMyMac X needs the Full Disk Access privacy control to enable thorough scanning in its System Junk, Mail Attachments, iTunes Junk, Privacy, and Uninstaller modules.

To provide CleanMyMac with essential permissions, do these:

  1. Switch to Full Disk Access and click (+).
  2. Open the Applications folder and select CleanMyMac X. If you're a Setapp user, go to Applications → Setapp → CleanMyMac X.
  3. Click Open.

Done! Now CleanMyMac can easily find all unneeded files on your Mac.
