I’ve a major 10.15 issue on two Macs where doing any kind of calculation in Spotlight maxes out all cores on the CPU for 10-15 minutes.

I just read about this here:

It's one of the most recent reasons I have yet to update to Catalina.

Oh huh. I use that feature pretty often. I have my fan speeds ramped up to max 24/7 so I never noticed mds_stores going crazy but - yep there it goes.

isn't this really loud? Will it wear out your fans faster? What is this solving for you at cpu idle?

I just did it, cpu did ramp up, but dropped right back to normal as soon as I closed the calculator. odd.

Friend, it's time for a clean install. You should never have to do one, but macOS isn't yet iPadOS, and cruft happens.

Sorry but that’s absolutely rubbish. You shouldn’t have to wipe everything from a computer to have it usable, ever.

Thanks, I laughed a little at that.

People have been saying exactly that for as long as operating systems have been on disk. I was thinking just a few days ago that I must have installed OS/2 50 or 60 times in its day.

I can't calculate the number of weeks of my life I've wasted babysitting clean operating system installs.

You're right, it shouldn't happen. But we're decades away from that being the reality.

The Catalina beta was a sh!tshow on my MacBook Pro, as was the first (upgraded) release. A fresh install made most of the issues go away.

It’s a new 16” that I set up new.

Wow, then my apologies for offering non-applicable advice. I'm crazy-curious what it could be.
