iCloud Calendar
I've been trying to sync my icloud calendar on my Mac but the option is greyed out. I tried everything! I had a similar problem with sycning my contacts from icloud as well.
In the Internet accounts section does not allow be to enable the calendar, or check off anything but photos, and find my mac. Everything is greyed out
I've signed in and out of cloud....did not work
