- Product
- Microsoft Defender
- Device & OS
- macOS Ventura
- Scenario
- Setting up Microsoft Defender on a Mac running macOS Ventura.
- Observed behavior
- The 'Next' button remains disabled during the setup process, even after the user has explicitly granted Full Disk Access permissions in System Settings.
Ensure you are logged in with an administrator account, as modifying Privacy & Security settings on your Mac requires an admin password or Touch ID authentication.
Remove and Re-add Microsoft Defender Extensions
By completely removing the existing Full Disk Access entries for Defender, you force macOS to correctly register the permissions on the next setup attempt.
Due to changes in how macOS Ventura handles System Settings, simply toggling the permission switch off and back on is often insufficient. Completely removing the existing entries allows the setup wizard to trigger a fresh, recognizable permission prompt.
Click the Apple menu in the top-left corner of your screen, select 'System Settings', and scroll down to click on 'Privacy & Security' in the left sidebar.
Under the Privacy & Security menu, locate and click on 'Full Disk Access'.
Find 'Microsoft Defender' and 'Endpoint Security Extension' in the application list. Click on them to highlight, then click the minus (-) button at the bottom of the list to remove them completely.
Launch the Microsoft Defender setup application once more. When prompted by the wizard, approve the new permission requests to successfully enable the 'Next' button.

Go to System Settings > Privacy & Security > Full Disk Access. Click on the specific application you want to remove, authenticate with your administrator password or Touch ID, and click the minus (-) button located at the bottom of the list.
