Just put on IOS 7 on its launch day on my iPad 4 and IPhone 5. They are synced with my MacPro with Mac OS 10.8.5 using BusyCal for my go to calendar. Used Busycal for years.
Everything worked perfectly before I did the updates.
Now my MacPro with BusyCal is fine but MacPro Apple Calendar has missing events from some of my IClouds 8 fifferent calendars same as iCloud. IOS Devices only have events from my iCloud home calendar showing nothing from the other 7 calendars.
Called Apple and levels one and two Apple Care people did not know what to do. IOS 7 was not available for the level two helper.
Thank you for guys for attempting to assist.
I am embarrassed to admit that after installing IOS 7, I needed to put in my iCloud password in the BusyCal program again. It runs perfectly now like it has alway done.
Appreciate you assistance.
