You must update your software, Because we are not using multiple monitors. Mac M1 give to us permission just one screeen and I am developer, so I have to work with multiple monitors. When I bought mac M1, that day couldn't happen.

Keith is correct. You would need a MacBook Pro or Mac Studio with an M1 Pro, M1 Max or M1 Ultra.

A developer should know that this a clearly specified hardware limitation with the M1, not a software limitation. you need a computer with a different Apple Silicon chip.

FWIW, the article you linked uses a combination of hardware and software which is not supported by Apple. The article also points out it may not work in a future version of macOS. It only covers Big Sur.

If you decide to go that route it would be at your own risk.
