After the 26.5.1 update, my Mac’s started to overheat: usually first thing in the morning, after initial boot up.
Checking Activity Monitor, yesterday?
I saw that the corespotlightd process was hogging resources.
So used the solution, here, to correct it.
For The rest of the day, at least.
This morning?
I’m still getting overheating.
How do I stop this?
On a long term basis?
Mac mini, macOS 26.5

Prevent Spotlight from searching the external Media drive.

It seems to be happening when Time Machine is active: my machine’s main drive, and my external media storage drive, are both backed up to a separate external drive.
Exclude the external Media drive from the TM backups.

Basically only allow Spotlight to Index the Macintosh HD and Time Machine to backup the Macintosh HD.
Then Restart the Mac mini and test it for a day or two.
Click on the section named "Constant value . . . " to the right of "Auto".
This adjustment window will open.
Select "Sensor-based value" and open the disclosure section to the right where you will find a list of all the sensors.
As you can see, I chose "CPU Core Average" as it appeared to make most sense to me but you are free to make your own decisions of course.
You can stick with the default temperatures you are given or select your own as I have done.
Finally click "OK".
Remember that you are also free at any time to go back to the "Constant value . . . " setting where you have a slider to instantly ramp up the speed to anything you want but when you have finished you need to reset it to the "Sensor-based value".
JUST as a thought … ?
The problems in this thread seem to suggest that Spotlight’s handling of indexing seems to be at the heart of the issue.
I don’t know if anyone saw this year’s WWDC, but Spotlight’s indexing issues are something the company said — at around the 13:45 mark — they would be addressing in macOS 27 …
FCP is really unhappy about something. Check for available updates for the extension involved:
https://github.com/CommandPost/FCPCafe/issues/534
webkit got busy, which can be a confused tab or junk in a tab.
Spotlight is busy too, but I’d wonder if that’s due to the crashing.
Just so everyone’s updated?
I’ve had Safari, Final Cut Pro, Pages and QuickTime open: and, going by Activity Monitor, corespotlightd and kernel_task have been going bonkers.
Nothing, I’ve seen, yet, seems to have helped.
The one thing that did … ?
Was using the rm -rf ~/Library/Metadata/CoreSpotlight/ command
Or opening ~/Library/Metadata/CoreSpotlight/ and manually emptying parts of it.
If it’s still the case that could help?
What do I empty from ~/Library/Metadata/CoreSpotlight/ … ? The plist files? The contents of Spotlight Knowledge?
This is frustrating!

Yes: I realise how Time Machine works!
I’m also aware that the Time Machine drive is *permanently* attached to my machine,: that, for the past few days, I’ve had overheating *when FCP is active.*
That, while it’s active, corespotlightd is showing up in Activity Monitor, hogging resources.
FCP is NOT crashing: it is, bar the over heating, working well, and continuously!
Cheers for that, Ian: that’s helpful.
However … ?
I think this is treating a symptom, rather that treating the disease.
Especially given Activity Monitor is still telling me the corespotlightd, kernel_task and spotlightknowledged.updater processor are hogging resources.
I would feel comfier knowing what I could do, there.
As an extra point?
It seems to be happening when Time Machine is active: my machine’s main drive, and my external media storage drive, are both backed up to a separate external drive.
Here goes:
I’m not getting issues with FC!
I’ve Started a new thread, here: Where do I move my music library to?
Every time FCP crashes you should Delete the Settings/Preferences.
If you don't it will continue to crash.
Right … With Macs Fan Control installed, FCP, Safari, and Pages, active MFC is giving me these readings.
Additionally?
Activity Monitor shows this:
Help!
OK … how do I configure Macs Fan Control?
I should add that corespolightd seems to be permanently on, whilst the over heating is happening!
How can I stop my Mac overheating?
