CrashPlan - Allow "Full Disk Access" on macOS devices

Important setting for CrashPlan macOS computers

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

Step-by-Step

Step 1: Grant full disk access to the CrashPlan app

You may be prompted to grant Full Disk Access permissions to the CrashPlan application.

Computers that are in the Endpoint Services program (JAMF) will have this access set automatically.

  • You can check in System Preferences (or System Settings) under the profile section to look for the CrashPlan MDM Profile. With this profile, full disk access is already set for your machine.

If you are prompted to grant Full Disk Access, you will see the dialog below.

Once you have allowed Full Disk Access, follow the steps in the next section to restart the Code42 service. The CrashPlan app will not have full disk access until the CrashPlan service restarts.

Step 2: Restart the CrashPlan service
There are two ways to restart the CrashPLan service: restart your device, or enter a command in the CrashPlan app command prompt. Choose whichever option is easiest for you.
Option 1

  1. Restart your Mac.

Option 2

  1. Open the CrashPlan app.
  2. If necessary, sign in to your account with your <netid>@dartmouth.edu as the username, then press Return (no password).
    • Crashplan uses Dartmouth's WebAuth (SSO) for authentication.
  3. Press Option+Command+C to open the CrashPlan commands prompt.
  4. Enter this command: > restart
  5. Press Return.
  6. This closes the CrashPlan app, reauthenticates the app with the CrashPlan server, and then restarts the CrashPlan service.
