Mac Air Calendar can't post events
When I add events to the iCloud Calendar on my Air, it will not propagate to other iCloud devices. However, events added at my desktop or Iphone will go to the Mac Air. The account setting on the Air is set to "Push".
Possibly related, but not as critical, it takes my Iphone several minutes (often as many as 30-60) to receive events that are made on another device.
Any thoughts appreciated. Thanks.
