#19 Emulators are not accepted on MacOS

[Edo Noordermeer]

As part of the emulators selection step in the EF workflow, a check is made against the OS for each listed Emulator. The listed Emulators are usually classed as 'linux' or 'Windows'. On MacOS, neither of these two types are accepted, and only those Emulators for which no operating system is defined, are accepted.

As MacOS is essentially unix-based, it is suggested that all Emulators listed to run under linux, are also accepted on MacOS.
