As answered by people managing Input Director and MultiMac.
MultiMac's answer:

MultiMac's answer:
Software engineers, designers, video editors, and remote professionals who work across two or more Macs (such as a personal Mac Studio/iMac and a company-managed MacBook Pro) on the same desk.

MultiMac's answer:
