Need help fixing iMessage (10.15.6)

so I have gone back to the hackintosh scene, since I left in 2017 because I didn't want the wifi dongle, but now I found a working kext. I have fixed almost everything, and the cherry on top would be iMessage and FaceTime. I tried the "An iDiot's Guide To iMessage" twice and it didn't work. It shows me "You cannot sign it to iMessage on this Mac at this time" and a customer support ticket number and phone number. Any suggestions?
