Hi all,
Since lastest release, 10.12 Beta (16A270f), I have been facing an issue with high CPU usage mainly for CalNCService and CalendarAgent which reaches more than 100% CPU usage.
I have tried to disable Calendar from the Mail account, kill, restart.. but none of this result any effect.
Does anyone have any workaround or resolution for it?
BR,
Jean
Same for me. Over 300% CPU usage and fans run continuously
Just taken a action disabling (removed) the Exchange email account and seems that "resolved". I am not facing high CPU usage since then.
This fix worked for me as well. Terrible performance to the point where my machine was almost unusable, and after simply taking the exchange account offline in the Internet Accounts pane I was back to normal in a couple of minutes.
Same here. I thought my Macbook was about to fry itself. I havent got an exchange account, just G Apps and a few local and remote calendars CalDAV. Anyone know how I can isolate....or is it as simple (and tedious) as disabling each of 15 accounts one by one until it resolves?
There is no solution for that.
Apple needs to FIX CalNCService bugs.
