MBP 13" late 2011 macOS 10.13.6 - Calendar app not syncing with icloud
My MBP is running High Sierra(10.13.6). The Calendar app on MBP does not sync with the icloud calendars. My iPhone6s(12.4.1) and my iPad4(10.3.3) will sync. I logged out of icloud on my MBP and when I logged back it will not sync the calendars, the calendar is empty on the MBP. The calendars on the iPhone6s & iPad4 are still intact.
