Interesting observation 🦉-53

Is this Mac being managed by an MDM? When I saw your picture, it made think of an MDM update panel due to the icon on it. I haven't installed any software updates yet on my Tahoe test system.

Welcome

OP wrote " I am using a mac mini m4 with OS Tahoe 26.1

I have the issue that every time after I restart I get the message that my software was updated. "

Perhaps a Screen Shot of this " I get the message that my software was updated. "

In theory and predicated on the Tahoe 26.1 was actually installed

It is difficult to see why this message should be presented

At least on 1 M4 Desktop, 1 M4 Laptop and 1 M2 Desktop each updated to 26.1

Not getting this message

Go figure

Thanks for trying to help but nothing worked actually.

So I decided to wipe my mac clean and install Sequioa.

Now everything works normal.

Judging from what has been shared from the beginning of the question to current

This issue seems localized and unique to your computer setup

The M4 Mac Mini was designed and made by Apple to run macOS 26 Tahoe

To share, also running a M4 Mac Mini which originally came with Sequoia 15.5

Have updated through all versions Sequoia until the release of Tahoe 26.0 released Sept 15, 2025

Since then update to latest Tahoe 26.2 and not experienced any of the issue you have outlined

In closing

If downgrading back to Sequoia worked - great

Ok and what happened when you clicked on " Continue " lower right of your image

No, its my private mac so no MDM is running

Sorry but you best address this issue to my colleague @HWTech

It was they who thought there was a MDM involved

I quote from a colleague of mine @ Ingo2711 who seems to have the answer to your question

If this works and hope it does

Any and all credit goes to my colleague

Since my MacBook Pro could not be upgraded beyond Catalina, when this happened in the past, I guess that newer Apple Account features on one device require to log out and log in on all connected devices. Especially when you use Passwords or FindMy, which sync information across different firmware versions. " END Quote

Completely normal

That is, if you had chosen and successful established a Wifi Connection
