The Calendar app on my iMac shows 8 duplicate calendars for each category: Calendar, US Holiday, Family, etc. I followed all the troubleshooting steps listed on the Apple site. The only account used to sync with this app is iCloud. I tried disabling/enabling iCloud, signing out/signing on with iCloud and restarting my computer, all to no avail. I do not have this problem on my iPhone 6+ and Macbook Pro.
Has anyone else encountered this problem? Does anyone have a solution?
Thanks.
