As far as I know there has never been more than the one operating

nope. on intel macs, windows is fully supported by apple via boot camp.
for older macs, apple had a port of linux for a while called mklinux.
third parties ported freebsd and others.

That has never been the situation with X86 machines. There has always
been a choice of operating systems for them. Microsoft took the line
with OEMs that if they wanted to install an MS operating system they
had to install it on all their machines. You could not get a machine
without an operating system.

true, which is why beos was squashed.
