pram reset M1 MacBook Pro Ventura

I've just started having problems with my MacBook Pro M1 running Ventura giving me a black screen, meaning that I have to hold the power key to shut down, then restart. I've run diagnostics and that's OK. I wanted to do a PRAM reset but didn't seem to have enough time between pressing the power button to press and hold Opt, Cmd, P and R. I shut down and pressed those four keys before I pressed the pwoer button, but pressing the 4 keys was enough to boot it. But it booted up normally, without a second chime.

Have I reset the PRAM, despite not having the second chime ? Is there a different way of doing a PRAM reset with Ventura ?

Thanks for your help,

Stuart

MacBook Pro 14″, 13.5

Suggest the User start with Points 1 to 4 and then Test


Still having issues, move onto Steps 5 and 6 and Test Again


Still no resolve - move onto Step 7 and follow instructions therein 


1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.


2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 


3 - Does the issue present in this mode ?


4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.


5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.


6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.


7 - Download the Application Etrecheck directly from the Developer.

M1 Macs = Apple Silicon computer


On M1 Macs, the NVRAM is tested during the startup process, and if the system detects a need to reset, it will.

There isn’t a key combination that you hold down while starting up the Mac.


If you would like the system to inspect the NVRAM on an M1 Mac, shut it down completely, wait a few seconds, and then power up the Mac.
