So the solution would be - running a dual boot with Windows on the Mac, then running RPA that way.
I would suggest the following steps:
NB to keep in mind that the dual boot Windows install must be a Windows Pro version, else the Active Directory authentication won't work correctly. This is not guaranteed to work. It should - but if you have a newer M1 processor then it could potentially be a problem.
Another alternative would be installing RPA on a network server and giving the user VPN access or remote access to the desktop to run the RPA app from there.
