Admin Menu > iCal and RSS > Click to enable iCal > Select categories to include in feed > Save
Note: iCal link appears at the botton of screen. iCal button appears on calendar nav bar.
STEP 2: Next, go to your Mac. In Calendar, choose File > New Calendar Subscription
STEP 3: Enter or paste the CalendarWiz iCal link, then click the Subscribe.
STEP 4: Enter calendar name and color. Review refresh options and set as you wish. Optionally, select Location as "iCloud" if you wish to pull this feed into other Apple devices. Click OK.
If you choose location to be iCloud: Apple recommends that you update your iPhone, iPad, and iPod touch to the latest version of iOS, and Mac to the latest version of macOS. Make sure you’re signed in to iCloud with the same Apple ID on all of your devices.
