iCloud Calendar doesn't sync to Mac
As of a short (not sure just when, it could have been the 10.9.5 upgrade) time ago:
• events created on iPhone sync to iCloud.com
• events created on iCloud.com sync to iPhone
• events created on Mac sync to iCloud.com
But nothing in iCloud.com syncs to my Mac without opening Calendar. And syncing doesn't continue if I leave Calendar open in the background: I have to close/re-open Calendar to get more events to sync.
As I like to create reminders of events on my phone when I'm out and about, and then have the reminder notification waiting for me when I get back to my desk, this is a big pain.
I've tested to see if there's something blocking iCloud by disabling my network filter. and firewall temporarily. No help. I've logged in/out of iCloud on all devices several times; restarted my Mac.Upon reboot of the Mac, everything previously added to iCloud syncs, but nothing added afterward goes through.
Any ideas?
