This tutorial explains how to grant full disk access for Bitdefender Antivirus for Mac in macOS Mojave, Catalina, Big Sur, Monterey, Ventura, and Sonoma.
Overview
With the launch of macOS Mojave (10.14), Apple has implemented a series of changes that by default block applications’ access to specific system folders and resources such as Mail, Messages, Safari, Time Machine backups. In order for Bitdefender to scan protected such locations, the user must manually allow full disk access to the Bitdefender Antivirus for Mac application files. Otherwise, security features such as the antivirus shield and system scan won’t work and Bitdefender Antivirus for Mac will display a Grant Full Disk Access recommendation. To keep your Mac protected, allow Bitdefender full disk access. Following the instructions outlined below, depending on your macOS version – Find out which macOS your Mac is using.

Troubleshooting – After updating to macOS Ventura, Bitdefender requests Full Disk Access
Due to a bug in macOS Ventura (13.0) that is yet to be fixed by Apple, all security solutions that were granted Full Disk Access prior to the macOS Ventura upgrade may be disabled, although they still appear to have full disk access in system settings. To overcome this issue in existing installations of Bitdefender Antivirus for Mac, you need to remove the Bitdefender entry from the Full Disk Access list and add it back. Follow these steps on your Mac:
Step 1
Click the System Settings 
icon on your Dock, select Privacy & Security, then open the Full Disk Access section.
Step 2
Select Bitdefender, then click the (−) minus sign at the bottom of the Full Disk Access list to remove this entry.
ⓘ Note: If you just toggle Bitdefender to the off position (gray switch) and then back to on (blue switch), the issue still occurs.
Step 3
After deleting Bitdefender from the list, drag & drop the 
icon from the instructions window to the Full Disk Access window, as shown below.
Alternatively, you can also:
- Press the (+) plus sign at the bottom of the Full Disk Access window.
- Then click Applications in the sidebar of the Finder window, select Bitdefender, click on Antivirus for Mac and then press Open.
Step 4
When prompted, input your macOS administrator name and password, then press the Modify Settings button.
After completing these steps, Bitdefender should be allowed and when you open the Antivirus for Mac interface it should no longer say “Grant Full Disk Access”.
