At idle ~100% cpu
Fan runs at a noticeable speed in the computer.
Any idea what to look for? Or is this expected?

When you receive 50 RBN spots per second or you have two full screen scopes in view, the CPU load will go high.
Without any reason I observed these sometimes when using the iCloud synced logbook. Restarting may help.

Hi,

Turned off iCloud synced logbook.
Restarted the computer.
No CAT connection.
No UDP (at least as I can see)
No DX cluster connected.

Still 100% CPU
