macOS Monterey compiling script

[Fourthbus]

Tested and working partly so far.
Working with .img file. Not working with SD card (Raspberry Pi SD card tested, input: fuse-ext2 /dev/disk2 ~/mnt/ext/ with nothing returned to the command line, nor anything mounted).

[OS] macOS Monterey 12.6.3
[device] MacBook Pro (15-inch, 2017)
[processor] i7-7920
