Installing the Backup Client on macOS 10.14 and Later

Matt Matt

In macOS 10.14 and newer, Apple has made significant changes to their Security and Privacy which can prevent our program from performing its job successfully. Here are a couple of workarounds for this. 

For macOS 10.14 and newer:

If you are running macOS 10.14 Mojave, make sure you're using the latest version of the client found on The initial installation process should walk you through making sure Full Disk Access is set correctly. If you missed it, you can set it later on by following these steps:

1. After updating to the latest client, open the Applications Folder. 


2. Open the System Preferences on your Mac by clicking the apple icon in the upper-left corner and select System preferences.  


3. Click Security & Privacy settings.


4. Select "Full Disk Access" in the left-hand column.


5. If necessary, click the lock and enter your Mac's username and password to allow you to make changes.

6. Drag the Backblaze app into the Full Disk Access location and release the Backblaze icon into it as show in the images below. 


7. Restart your Mac. After reboot, once Backblaze does a hard drive scan it should back up everything that the Mojave upgrade excluded and your backup should remain safe! 


For macOS 10.15 and newer:

Note #1, the above settings for Full Disk Access is still required.

Note #2, if you're using macOS 10.15 Catalina or newer, make sure to install the latest version of the client found on

If you have external or secondary hard drives connected to your Mac that you would like to backup with Backblaze, and are running macOS 10.15 Catalina or newer, you will need to grant "bzbmenu" access to your removable volumes.

Typically macOS will display a dialog asking if you would like to give bzbmenu permission to read your external or secondary hard drives. If you see this dialog, simply click "Yes" or "Allow" and no further steps will be required.

If you accidentally click no, you can go into your Security & Privacy settings, navigate to "Files and Folders", and make sure that the "Removable Volumes" checkbox is selected for bzbmenu. 


Once selected, you will be able to continue backing up external hard drives! Make sure you connect all selected external drives to your computer to allow bzbmenu to verify access on each individual drive, or you may continue to see the dialog after granting permission.


For macOS Ventura:


As in the above two cases, Ventura still requires Full Disk Access, and you will want to be sure that you have updated to the most recent version of the client found at


1. Open "System Preferences" and select "Full Disk Access"




2. You will see a list of applications, if Backblaze does not appear in this section select the "plus" icon.




3. Navigate to the "Applications" folder, select "Backblaze", and then select the button labeled "Open"




4. Backblaze will now appear in the applications listed in the Full Disk Access menu, make sure the toggle is selected to allow Full Disk Access for both "Backblaze" and "bzbmenu".
