CalendarAgent consuming CPU
There has been a series of questions over several years on CalendarAgent suddenly going crazy to consume CPU and causing the fan to run continuously. I'm on 10.12.6 on a MacBook Air, and that has now reared up. Fan runs loudly, all the time, and consumes the battery in about an hour. This was never a problem before. WTH is the deal on this, and why is there not an APPLE fix to it?
MacBook Air, macOS Sierra (10.12.6)
