errors 9039 and 11571 on iMac
Cannot log into AppleID on my iMac. Getting errors 9039 and 11571 when I try. At first it was just error 9039, but after I de-authorized the iMac with my iPhone, changed the AppleID password and reauthorized (after having made sure software updates were current etc. in an attempt to resolve the initial error), I started getting the second one as well. I can find nothing useful in regard to this problem online. Any ideas?
This is beyond annoying.
iMac 21.5", macOS 10.14
