Hello Folks,
So yesterday I started to have issues with the iTunes store, not being able to purchase content. The issue was probably due to something going on with invalid or not verified certificates in the Keychain Acess.
In the attempt to fix it, I messed around with some keychain certificates. This morning, I realize that my iCloud Calendar does not work and want to sync. When I open Calendar on mac, I get a pop-up message:
On the left of the calendar window, where you can select visible calendars, I see a warning sign next to iCloud.
I think this is due to a certificate issue. I had the same problem with iCloud Contacts, but was able to fix it. However, I think the calendar certificate is different from the contact certificate.
When I click on the warning sign, it does not show me which certificate is being problematic.
Any help would be very much appreciated.
