Hi @Raz Aspir ,
Do you mean Entra ID (old name is Azure AD) or is it Intune enrollment also?
If you will control the device and apply policyes and so to it, you need Mac OS 11 or newer on your MacBook Pro Retina 2015. As I can read about it, the device "should" be to old.
But I will recommend you to read this also: https://learn.microsoft.com/da-dk/mem/intune/user-help/enroll-your-device-in-intune-macos-cp and https://learn.microsoft.com/en-us/mem/intune/fundamentals/supported-devices-browsers.
How to find your current install Mac OS v. MacBook Pro Retina 2015 can you see here how to find it: https://support.apple.com/en-us/109033
I hope this helps (not a daily Mac OS user)
