I've clean installed Sonoma and have Apple ID issues

I've been using my hack since four years without any Apple ID issues. Messages, facetime etc. everything has worked smoothly since then.

Last week I updated my opencore and reinstalled Sonoma from scratch. When I enter my Apple ID credentials keychain access, safari bookmarks, notes and calendar have synced correctly. But messages did not work.

I see "This device cannot be used to receive Apple ID verification codes." message when I click on the iMacPro on the device list. And on the line where Find My Mac sits I see "DEVICE_LOCATOR_IMACPRO".

When I check the message settings on my iphone I cannot see my computer on the message forwarding list.

Is there anybody here that has lived a situation like this? I did not change my SMBIOS by the way.
