F5 MAC edge client SAML intune

Hello,

I hope someone can help with an issue that i have.

I have created a F5 vpn for developers, that is using SAML for authentication and the BYOD will also checked if device is compliant in Azure AD. 

Somehow when developers has a macbook and installed an edge client software, it will not connect with VPN. In the mac edge client screen it shown Device Identifier is not available  and device state is unregistered. i know for sure the macbook registered and managed. 

Windows edge client has no issue.

anyone know how i can fix this?

Thanks.

Regards,

Lee
