Something is seriously wrong with my Macbook!!

First I've heard of kernel extensions, quick google brought me up to speed. Seems to coincide with a Catalina update maybe??

Should I nuke them?

1. I think I have duplicate installs of system files as I have a metric $h!t ton of these:

rtcreportingd[5530]: objc[5530]: Class RTCReporting is implemented in both /System/Library/PrivateFrameworks/RTCReporting.framework/Versions/A/RTCReporting and /usr/libexec/rtcreportingd. One of the two will be used. Which one is undefined.

Thanks for the quick responses btw.

Thanks for the tips. Ran the Terminal first...

$sudo mdutil -E /
Password:
/:
	Indexing enabled. 

No noticeable difference.

I've been paying attention to performance degradation and have noticed the following:

• scrolling websites can be choppy
• scrolling Apple Arcade - Apple (CA) is impossible.

Did the GUI link. Will advise if I see anything change.

I believe I had tried 'the nuke' a couple weeks ago but I may have to try again.

Saw the following in AM today. Thought the disk access was high but can't say as I've paid attention prior.

And this is 90 minutes later....

Reboot. Spotlight is lightning quick now, but I did nerf most of the selections.

I was able to catch I believe just before my restart and through the boot process in system.log with another 2 hours later.

UPDATE: 2hr15min later and syslog is kicking out a least 2 per minute but seems better.

First off, thanks for everything thus far.  Your patience is godlike.  I'll definitely check out GrandPerspective.... in a bit.  I think I'm getting somewhere but want to run it by you to see if you think I'm off in the weeds again or not.

I use this laptop to do Rails dev, well, I did Rails dev for about 6 months before getting pulled back into the consulting world for a 3 year gig.  I only recently picked up my personal project around June (in earnest) while still have an MVP of my web project running for about 10 users.  I was hesitant on upgrading anything, especially to Catalina due to a fear (probably wrongly founded) of breaking compatibility of many things my old project may have depended on.

I vaguely recall needing to upgrade openssl from 1.0 to 1.1 for some reason.  (Ruby or Rails upgrade would be my guess) but needed to upgrade XCode, which required a macOS upgrade (don't count all that as gossip) and ended up using (I think) homebrew to do it.

Again, I'm not noticing any failures or super noticeable poor performance in most of my tasks.... just the ugly console log.  I'm starting to think it's because of two conflicting XCode Command Line Tools installations.  Here's a console blurb:

But that may mean nothing.  Here's my Terminal output while running down this vague thread.  I'll explain on the other side.

So first I confirm that I have XCode installed, and then try gcc as that is supposed to work if the Command Line Tools are installed, but it fails with

clang: error: no input files

yet gcc -v works, as does gcc --print-search-dirs

I could be going down the wrong path here so I'll just get to my question.  Do any of those items listed after my brew list look like an XCode Command Line Tools?  If so, then that's most likely the issue.  Here's my brew config output:

It looks like I'm on the right path as I get no results when running the command found https://github.com/nodejs/node-gyp/issues/1927#issuecomment-544450426-permalink:~:text=com.apple.pkg.CLTools_macOS_SDK-,If%20you%20get%20nothing%20returned%2C%20please%20do%20sudo

I'm going to continue down this rabbit hole.  Would love to know if anything jumps out at you or not on what I've written above.  Besides that I know just enough to be dangerous....
