New Macbook Pro 2021 - not able to install OS X Big Sur

Hi there


Just received my new MBP 2021 and tried to install OS X Big Sur on it. My goal is to run both versions of OS X (Sur and Monterey) parallel.


Now i really struggle and can't get it to install big sur. I erased the disk completely and created and external booter with Sur. Now in the install menu of the OS installer i Only get the "update cannot be installed on this computer" error and am unable to proceed.


Any thoughts on this? My thinking was that it should work like a charm to downgrade it to Big Sur. I would have to return the product if there isn't a way to get big Sur up an running...



MacBook Pro (2020 and later)
