How do I reset PRAM with a non-Apple keyboard on a Mac Mini?
The normal procedure to reset PRAM (Command Option P R) doesn't work when I use a non-Apple keyboard on a 2018 Mac Mini. How do I reset PRAM while using a non-Apple keyboard?
The Command and Control keys are reversed.
Try Control Option P R
If that doesn’t work, open your keyboard viewer and try the different keys.
