Some applications include system extensions that macOS blocks by default. Extensions let third-party Mac extensions add extra functionality to apps with the share option, touch bar, and more that can be found on Apple's Support Page on Extensions.
Select System Preferences (macOS 11-12) or System Settings (macOS 13) from the Apple Menu in the upper left corner of your screen.
Select Security & Privacy (macOS 11-12) or Privacy & Security (macOS 13)
In the Security & Privacy click the General Tab (macOS 11-12) or scroll down (macOS 13)
In the section Allow apps download from, click the Allow button.
If Allow is grayed out: click the lock, click Allow, click the lock again to stop making changes (macOS 11-12).
