Giving Déjà Vu Full Disk Access

macOS Mojave introduces new privacy restrictions which prevent apps, including Déjà Vu, from accessing certain application data such as your Calendars, Photos, Messages history, and Mail database. Unfortunately, the system will not prompt you to allow this access. Instead, you must manually pre-approve them by completing a series of steps which we find rather cumbersome and inelegant. We have done our best to make the procedure as simple as we could, however, and it is our sincere hope that you should only need to perform these steps once.

The first time you open Déjà Vu on Mojave (or later), a new Privacy Assistant window should appear at the top-right of your screen. Please follow the instructions it contains. After you have successfully completed these steps, the Full Disk Access section of your "System Preferences > Security & Privacy" preference pane should contain the entries shown below. When System Preferences prompts you to quit now or later, choose Quit Now, and be sure to close the Privacy Assistant once you have finished. (Did we mention that you should only need to do this once?)

Déjà Vu does its best to automatically display the Privacy Assistant window when necessary. If needed, though, you can display it yourself by holding down the Option key and choosing Show Privacy Assistant from the Déjà Vu menu icon. Note that this will only work when no backup is in progress.

  1. Déjà Vu uses rsync for copying files. If rsync is not added to the list of allowed apps, some of your important data may not be copied.
  2. Déjà Vu uses cron to perform scheduled backups. If cron is not added to the list of allowed apps, scheduled backups may not have access to some of your important data.
  3. Rather than being a normal application, Déjà Vu is a preference pane which runs inside of System Preferences, its host application. In order for Déjà Vu to function properly and have access to your data, the System Preferences application needs to be allowed full disk access.
Problems With Dragging and Dropping?

Déjà Vu's Privacy Assistant window asks you to drag and drop the required files from a Finder window into the list of allowed apps shown above. If the dragging and dropping procedure is difficult or impossible for you, you can follow these alternative steps to achieve the same result:

  1. Click the Open Security & Privacy button in the Privacy Assistant window, then click the lock icon to make changes.
  2. Click the + button to add a new item to the list.
  3. Use the keyboard shortcut ⌘⇧G (Command-Shift-G) to display a "Go to the folder" prompt.
  4. Enter /usr/sbin/cron and click Go.
  5. Click the + button again.
  6. Use the keyboard shortcut ⌘⇧G (Command-Shift-G) to display a "Go to the folder" prompt.
  7. Enter /Library/PreferencePanes/DejaVu.prefPane/Contents/Resources/rsync and click Go.
  8. Click the + button again.
  9. Navigate to your Applications folder. If unsure, you can use the keyboard shortcut ⌘⇧A (Command-Shift-A) to get there.
  10. Select System Preferences from the list of apps.
  11. Click the Open button.
  12. Choose Quit Now when prompted by System Preferences, and click Close to dismiss the Privacy Assistant.
