Summary: Once every while I notice my fans kicking in, and checking activity I see CalNCService using high CPU percentage. Steps to Reproduce: I don’t know how to reproduce it. Expected Results: CPU should not stay that active. Actual Results: I didn’t time it, but I’d estimate it stays active more than 10 minutes - 1h or so. Version: 10.13.2 Beta (17C67b) Notes: I have one iCloud, two google, one facebook account, each with calendars activated.

We don't have enough information to investigate this issue.
I have never heard of CallNCService. I also don't think we own this service.
