Thanks @Singleton . I am trying to rule out any hardware issues with the Mini M4, since I’m within the return window… is that a possibility?
It seems less likely if there are others with Mac configs and much the same issue. Relief that this isn’t just me, I’d just started reading this thread…
The actions proposed are a “dig out the roots and start all over again” which I’d rather not have to go through. Is that the first course of action?
