Hi @Anjana R ,
It is not possible to join a Mac device to Azure AD. But like you said, it is possible is to enroll your device using Intune.
To enroll a personal device in Intune: https://learn.microsoft.com/en-us/mem/intune/user-help/enroll-your-device-in-intune-macos-cp
To enroll a company device in Intune: https://learn.microsoft.com/en-us/mem/intune/user-help/enroll-company-device-macos
Hope this helps!
