Install the Backup Client for MacOS 10.14 and Newer

In macOS 10.14 and newer, Apple made significant changes to their Security and Privacy which can prevent the Backblaze client from performing successfully. There are a couple of workarounds for this, starting with the most current operating systems.

Install the Backup Client for MacOS 13 Ventura or Newer

If your computer is on macOS Ventura or later, ensure that you use the latest version of the client. The initial installation process shows you how to correctly set Full Disk Access.

1. Press and hold the Command key on your keyboard, and press the spacebar to open the Spotlight search.
2. Enter full disk access, and press return.
   The Full Disk Access panel opens within System Preferences.
3. Turn on the toggle switch for both Backblaze and bzbmenu.
   Older versions of MacOS may use a checkbox instead of a switch, and you may be required to unlock the Full Disk Access window by clicking the padlock. You may be asked for the computer password.
4. If Backblaze does not appear in the list, use the plus in the lower-left corner of the Full Disk Access window to add it or drag it from the Applications folder. 
5. Restart your computer.
   After Backblaze scans your hard drive, it begins backing up your data as normal.

Install the Backup Client for Mojave 10.14 to Monterey 12

If your computer is on macOS Mojave 10.14 to Monterey 12, ensure that you use the latest version of the client. The initial installation process shows you how to correctly set Full Disk Access.

You must also use this procedure if your computer is on Catalina 10.15.

1. Navigate to the Applications Folder.
2. Click the Apple menu, and select System Preferences.
3. Click Security & Privacy, and select Full Disk Access in the left menu.
4. If necessary, click the padlock and enter your computer's username and password to allow you to make changes.
5. Drag the Backblaze app into the Full Disk Access location.
6. Restart your computer.
   After Backblaze scans your hard drive, it begins backing up your data as normal.

Grant Access to External or Secondary Hard Drives for MacOS Catalina 10.15 to Monterey 12

Before you begin: The previous procedures to set up Full Disk Access are also required.

If you have external or secondary hard drives connected to your Mac that you want to back up and your computer is on MacOS Catalina 10.15 to Monterey 12, you must grant "bzbmenu" access to your removable volumes.

Typically, MacOS displays a dialog box that asks whether you want to grant "bzbmenu" permission to read your external or secondary hard drives. If you see this dialog, click Yes or Allow and no further steps are required.

However, if you click No, follow this procedure.

1. Open System Preferences, and navigate to System Settings.
2. Select Privacy, and select Files and Folders.
3. Click the padlock to make changes.
4. Under bzbmenu, select Removable Volumes.
5. Connect all of the selected external drives to your computer to allow "bzbmenu" to verify access on each individual drive, or you may continue to see the dialog box after you grant permission.
