Hi!
Didn't Apple switch to Apple Silicon processors by 2020?
If your Macbook has an Apple Silicon processor, give up. Its completely IMPOSSIBLE to install and use x86 Software, therefore its impossible to install Windows 7. they are different Architectures, with different instruction sets and are not compatible with eachother.
But if your Macbook is Intel (x86) based, the architecture is supported. you can try BootCamp.
But still your chances are low since the hardware is just too new.
