When I turn my Mac on it goes to Apple logo and the start up bar appears. Within a short moment the screen flickers and a red square flashes on around the Apple logo briefly before the schematic of the underside of a mouse appears and then what looks like the side of a laptop. The strangest thing is that I’ve never connected a mouse to this laptop, having only ever used the trackpad. This is where it gets stuck during start up, flashing between these two pictures. I’ve tried the steps for recovery using shift option command R
command R
option command R but none are working and the same thing happens each time.
I also notice that the cursor is displayed on the page but is frozen.
Any advice would be greatly appreciated.
