Do you know why it happenes?

There is a 403 from the mirror, not sure if this is the cause or not.

Had this same problem; following the docs/guides/supported-systems.md, readily solved by updating my .zshrc:

export MONGOMS_ARCH=x64

OSX ARM is not supported by default in 6.x, but since 7.x it is automatically translated to use what @jeffrey-dugas-neo said (to use x64, because mongodb does not provide any native builds yet)
