Macbook Pro M1 login crash to off state
I return to the machine and find it is off. I start it up to get the login screen, I enter the password and the screen goes black. It seems that it completely shut down because I press the power button I get the startup gong and the whole thing repeats.
If I hold down the power button and try to start up in safe mode, it immediately shuts down to the black screen. If I choose ‘options’ instead of safe mode it instantly shuts down again. After 10 attempts, I eventually get into the “options”. I then tried to reinstall monterey and got this error “This volume cannot be downgraded.”
Eventually, after about 20 login attempts the system will load. It may remain stable for an hour or a month. This is the third time it has happened and I can no longer rely on the machine for work.
I have removed all the login items except Calendar. I have reviewed the unsigned apps
Any ideas please?
