CPU usage too high on Mac.
The CPU usage is too on Mac computers. CPU usage on MacBook Pro is too high. CPU usage is at 20% all the time and the fan is running constantly. One Drive drains the Battery in one hour. If I close the app everything is fine.

Totally back you up on this. It uses 1 CPU core almost constantly. It no longer has a drop-down menu so the only way to quit it is in Activity Monitor. I restarted it about 1:30 hours ago and it had used 1:20 hours of a CPU's time. It's the fan on constantly that is usually the first sign. Honestly, it's one of the worst pieces of software on my Mac because it's been like this on and off for a year or two.
