My iMac won’t start up. I get the apple icon and the white progress bar but only a pinch of white. Then it cycles between a black screen and the icon with the progress bar that does not progress
Mac mini 2018 or later
Please try resetting the NVRAM and restarting in Safe Mode. If neither work, please take it to your local Apple Authorized Service Provider to be diagnosed for whatever hardware failure it has suffered.

I am not saying that this is the problem, but it could be. It's possible that the system doesn't like a connected peripheral. ( had this experience.) Restart after disconnecting everything and see if it finishes the start up. If so, then you should add one or two peripherals and again restart to see if it finishes loading. Complete this process until you find the offending 'connection'. Then I would reconnect that peripheral into a different port and see if that works ok. I my case the offender was that my mouse was plugged into a port on the keyboard that somehow caused the problem. So, I plugged the mouse into the port on the other side and - problem resolved. Good luck.
My iMac won’t go beyond the apple icon with a pinch of white along the progress bar below the icon. What can I do?
