Installing Bitdefender on a Mac running Big Sur or above you are going to get the alert from gatekeeper Warning you of the System Extension Blocked. The Application is SecurityNetworkInstallerApp which is trying to load the system extensions. This will need to be enabled by open Privacy & Security in System Settings and click ok or allow depending on the screen. This is relatively simple on Macs ruing Ventura or below. However with some recent builds of Sonoma and Sequoia the App does not appear in security to allow you to authorise the app.
On BitDefenders website they go into great length on how you do this however it does not highlight the issue with the later builds. I am not sure why the issue has arrived and I found the google answer was not there. Anywhere on the internet. Hopefully my blog will pickup where BitDetender has failed to update their support articles.
Here is the Bitdefender linked article which can help you on the older OS but not Sonoma or Sequoia.
When you google the issue you may come across Nordlocker which seems to have the same problem but the principle is the same. click here for their link.
I ran this on several build and only one machine popped up the alert and allowed me to click it in Mac system settings, which means this is across the board.
So to the fix its rather simple one you spend about 2 hours on a machine trying to find the solution that googling did not.
