I have an M4 Mac mini, bought last year: when running macOS 15·x
After upgrading from macOS Tahoe 26·0·1 to 26·1, I’ve notice the occasional freeze when lots of apps are open.
And that the thing seems to over heating: far more than it did under 26·0·1.
Does Anyone know what’s happening?
Or how — bar rolling back to 26·0·1 — to solve this?

Original Title: Overheating Mac mini
Mac mini, macOS 26.1
To address this question of yours " Does Anyone know what’s happening? "
Also running a M4 Mac Mini with Tahoe 26.1 which does not present of go the issues you have described
Part 1 of 3
Restart the computer in Safe Mode
Do the issues persist ?
Sometimes a Safe Boot followed by a Normal Boot will just put things right.
If not - there could be something in the main User Account playing up.
To further isolate this - Set up users, guests, and groups on Mac.
Then log out of the Main User account and log into the dummy account and test again if the issue persists.
If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.

No, that's fine. That's well within the range of variability for speed tests. One could run the same test on the same machine and come back with values that are even more disparate.
Plus, the first one did have some measurable I/O activity. That would also explain a slight decrease. It isn't exact math because I/O is a shared system and hardware resource. Even a little bit of activity querying file system attributes, not even reading or writing data, will slow down the read/write speeds of other tasks.
Thank you for your expertise

There have been several suggestion already put forth
What has the user ( you ) attempted from any of the 3 different suggestions ?
Well … I’m not deliberately using Pages with iCloud.
Although the files are showing up iCloud>Documents>Paul’s Documents>Unfinished Quizzes>Example files.pages …
Found that thread and for your reading purposes
Here is the link
OK … boiled down into plain English, Owl, what am supposed to be doing?
Has it worked for others?
I don’t think I’ve got a dongle: I just have an HDMI cable connecting the Mini to a 27” U27B3M: I have the monitor set to 2k: although it’s capable of 4k.
(The cable was new: about a year back.)
