Recently my MacBook Air (2016) has been randomly giving me this screen. Longest it’s ever lasted was a minute. One time I had to shut down the computer to get it to go away, another time it went away on its own. Does anyone know if there is a quick fix?
Reset NVRAM or PRAM on your Mac
Settings that can be stored in NVRAM include sound volume, display resolution, startup disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart.
