iCloud login from iMac
I can't log in to my iCloud on my iMac. I can log in from other devices.
I can log in through a browser. But I can't log in through system
preferences, iCloud. I just get a "You can’t sign in at this time. Try
signing in again". I have done a comple erase of hard drive and a
reinstall. Still no luck, When I did the reinstall, and it asked me for
my iCloud details, I filled them in and got a "Couldn't sign in because
of a server error. Try signing in again".
I see others have had this issue in the past but none of their suggestions have worked. The only thing I can imagine is that this iMac has serial number which my iCloud account has barred. But I've had the same mac for years (possibly too long but not for this).
iMac 21.5″, macOS 10.12
