This is why you should use a private CA for your EAP certificate and use tooling (Group Policy, MDM, Onboard) to get your clients configured for 802.1X and server trust.
If MAC clients manually trusted the server certificate, it's possible that when you change the server certificate that they won't connect.
How do you provision your clients?
