I am fairly convinced my non-Touchbar MacBookPro13,1 does
not even have T1 (in the MacOS system properties there are no
controllers and Apple Pay is not available), but the initial
version broke my system as indicated.

After running the following for a week:

all those come from Tue Aug 25 02:35:45 2026 +0200 till Wed Aug 26 01:23:43 2026 +0200

Today after building some ports and installing rustc package
I got a hard hang on the storage.

The system was perfectly usable on the user interface -
existing ssh versions worked, I could switch dwm workspaces etc.
but anything touching the ZFS hanged hard in one moment.

I can't see the text console so I don't know what happened exactly.

Fortunately it worked after the reboot
