I try to update the software of an older Mac, but I get the following message (in red) right under the AppleID box.
MZFinance.BadLogin.MacAppStore_message
Does anyone of you have a clue how to fix this?
Thank you in advance for your help!

Hi hbaat,
Welcome to the Apple Community.
Apple Support have articles online that may help:
First:
Identify your iMac model
(NB: locate your iMac model in this article (link below),
and see the "Latest compatible operating system" that is listed underneath it.)

Then:
How to get older versions of macOS
(Safari uses the links in this article to find the old installers in the App Store).

And
If you can't connect to the App Store, iTunes Store, or other Apple services

Hope this works for you :-)
