I don't have Windows, only Mac. Copying and scanning is not possible.

Yes, it works for Windows 11, but it's not a multifunction printer, so it can't copy or scan. For that I recommend the Brother MFC-L8690CDW, which is even a colour device and also has an integrated fax, if you still need one. It has a very good price/performance ratio. However, there are also much cheaper Brother multifunction printers; I would simply not choose an inkjet printer. Brother also currently has interesting cashback offers > https://www.brother.ch

It can't copy or scan! I don't have Windows, only Mac, and the printer runs perfectly.

Print b/w yes
Scan and copy no

I operate the printer with Windows 11 - without any problems.
