iCloud syncing not working on MacOS
Anyone else having this problem? My iCloud mail seems to be working perfectly on all devices except for my iMac. There's no overall "Mail isn't in sync with iCloud" message, but I'm not getting new mail and I can't move or delete anything stored in the cloud. Thoughts. I know the best thing to do is probably to disconnect from iCloud and reconnect, but that process always has so much collateral impact that makes it unappealing. Any help would be appreciated.
iMac with Retina 5K display, OS X El Capitan (10.11.1)
