Some apps like Crashplan/Code42, Sophos, VM Fusion, and Spirion are not functioning properly after upgrading to macOS 10.14 Mojave or macOS 10.15 Catalina.
Certain applications need access to the whole disk in order to function properly. This will require explicitly allowing the applications to access the full disk.
This example uses screen shots for CrashPlan, but the same steps will work for any application that needs full disk access
- Open Apple System Preferences.
- Open Security & Privacy.
- Select the Privacy tab.
- If privacy settings are locked:
- Click the lock icon in the lower-left corner.
- Enter your device password.
- Click Unlock.
- In the left pane, select Full Disk Access (you may need to scroll down).
- In the right-hand list, scroll down to your application, in this case CrashPlan, and check the box next to it.
Result: You see a message that Crashplan, or another app you chose, will not have full disk access until it is quit and restarted.
- Click Quit and Reopen.
- (Optional) Click the lock in the lower-left corner to re-lock privacy settings.
- Depending on the application, you may need to restart your computer to make sure that all services associated with the applications are restarted.
