Where is camera extension in Mac settings?

Can't find the "Login Items & Extensions" page? Open up System Settings using Spotlight Search & then searching for Login Items and Extensions:

Then continue following the Mac Install guide.

If you are on an older MacOSX (12.x), it might be in the general tab of Security & Privacy. Or it could be in the Privacy and Security settings when you scroll down. If you have several extension requests, you may have to click Enable System Extensions and then enable the one requested by FilterOnMe. If you're on a beta version of MacOSX, you may find it in the extensions section underneath the Others heading. Can't find where camera extensions are? Do an online search for "where are camera extensions or system extensions on mac {Your MacOS Version}".

Minimum version supported is MacOS 12.4.
