macOS not backing up files with personal data


Due to Apple's privacy restrictions for files and folders containing personal data in macOS Catalina 10.15 and macOS Mojave 10.14, Code42 cannot back up some files from locations like the desktop, Contacts, Photos, and Mail until you grant access to the Code42 app.


  • Devices running macOS Catalina 10.15 and macOS Mojave 10.14.
  • The warning message shown below may appear if the administrator chooses to show the message.
Granting full disk access to Code42 is only required once
If you already followed the steps below to grant full disk access to Code42 on macOS Mojave, you do not need to repeat these steps after upgrading to macOS Catalina.

Dismiss the warning message

Select the Do not show this warning again checkbox to prevent the warning from appearing the next time you open the Code42 app. 

The message only appears if full disk access is not granted to Code42. If you do not click the checkbox, the warning continues to appear every time you open the Code42 app until you perform the recommended solution to grant full disk access described below.

  10. (Optional) Click the lock in the lower-left corner to re-lock privacy settings.
