I was using system profiler to refresh my memory on what my old macbook pro has and noted the diagnostics option under Hardware. It listed two items in bold - one the Hardware Diagnostics Test I ran in Jan 2017 and another one whose name I don't remember. I have frequently done the shift + start before doing my superduper bu as recommended by superduper and I wondered if the forgot-the-name referred to that.
When I went back to find the name to google it for more info and see what it said under the bold only the Hardware test was listed. I've only used system profiler and disk utility that I can remember this afternoon and see no other options in either listing diagnostic tests by name. Is shift + start even a diagnostic test? I mean if the mac works when you start it that way it indicates a bad font or incompatible login item, but it doesn't give a report, does it? I don't see it in Logs. Would it have been listed in system profiler?
I am trying to refresh my memory on everything mac I learned after years as a disgruntled windows user and have forgotten over the last few years of strife and reduced activity.
