Navigate to System Preference > Security and Privacy > Privacy > Accessibility.To start controlling a Mac device of version 10.14 and above during remote support and unattended access sessions, accessibility and screen recording permissions have to be configured for Zoho Assist. Hence, Zoho Assist wouldn't have sufficient permissions to remotely control your customer's Mac desktop. With the privacy restrictions in Mac devices of version 10.14 and above, accessibility and screen recording permissions to the computer is denied by default. Why am I not able to remotely control Mac devices above version 10.14?
