iCloud started acting very odd today. I initially noticed this as the Messages app complaining that I needed to log into my iCloud account. I performed this action multiple times, but keep getting kicked back to the login dialog.
I tried logging out of iCloud entirely, but I am unable to log back in now. Again, the user/pass seems to be accepted, but I keep getting bounced back to the login screen.
I am able to log into icloud.com, so the account is ok.
In reviewing the release notes, I did see a note that 2010 and 2012 Mac Pros may have an issue logging into facetime and messages, but I'm running this on a Mid-2015 Macbook Pro.
Has anyone experienced this? Any known workarounds?
Thanks,
Jason
