If you see a message stating that your computer has detected a potential problem

Your Mac periodically checks for unexpected firmware changes and allows you to transmit information about such changes to Apple.

If your Mac detects a difference between the firmware that's installed on your Mac and the firmware that its operating system (macOS) expects to see, it will display a message stating that “your computer has detected a potential problem”. Firmware is software that allows your Mac hardware to work with macOS. Firmware that has been damaged or modified may affect the stability and security of your Mac.

To help Apple improve the stability and security of Mac computers, click Send to Apple to submit a report to Apple. You can also choose to show the report to see the information that will be sent and opt not to send it.

Then install the latest software updates, which can include firmware updates and other updates that are important for the stability and security of your Mac.
