Spotlight completely broken macOS Tahoe
My organisation bought me a new Mac mini, it has plenty of storage and, for the first couple of weeks Spotlight was working fine. However, it then stopped working. I and one of our IT guys have tried all of the fixes we could find but nothing worked beyond one search. Since (stupidly) updating to Tahoe in the hope it would resolve the issue things are even worse. This is what Spotlight looks like in Systems Settings now it has a permanently spinning ball and no list of things to search:
I had a call with Apple Support but the guy I spoke to just told me to do what I have done umpteen times i.e. to exclude the HD from searches and then reverse that action to kickstart indexing. The process seems to start each time but does not complete. I have left the computer running overnight etc to give it time to do this. I am unable to easily search mail, calendar, files or apps which is very problematic. Can anyone advise?
Mac mini, macOS 26.2
