@Kirubakaran Vethamoorthi, Thanks for posting in Q&A.
Based on my researching, I find Azure AD does not support direct integration with macOS for authentication. However, you can use third-party solutions to achieve this. One such solution is to use a tool like NoMAD or Jamf Connect to enable users to sign in to their Macs using their Azure AD credentials. These tools provide a single sign-on experience for macOS users and can be configured to work with Azure AD.

But as Intune support, I am not familiar with this. To get more help, I have added both "Azure Active Directory" and "Microsoft Entra" tags to see if AAD support will be added into to help on this. Or you can open a new thread with the two tags to see if you can find the support.
Thanks for your understanding.
