Update done without any problems.
And you should do more tests with MacOS: Every new version brings new solutions and new problems too :-/

What date should the new certificates have? Currently, it is as follows:

It was the same before the update.

11. Updated the firmware for the F8 SSD / F8 SSD Plus.

Is that applied automatically and what is the change log / fix? I had to update PCIe firmware manually in the past ( viewtopic.php?p=49736#p49736 )
Is this the same update, now integrated or does it update something else? How do I check if it applied correctly, like I could with the update linked above?

Yes, the firmware update included in this system update is the same one you previously performed manually. Therefore, there is no need to repeat the update. The method to verify whether it was applied successfully matches exactly what was described in the post you referenced—you can confirm it just as you did last time.

This certificate update is only visible in certain scenarios, so your certificates likely renewed automatically even before this update.

Updated my F4-223 seems fine so far. The update dialog box only got to 9% then I heard the unit beep. I assumed the update was complete.
Waited a few minutes and refreshed the browser. All is fine.
Next is the F4-424 Pro but a bit later.

Thanks, update of an F8 SSD went fine.
