Hook taking 70-75% CPU in the background

I have noticed that on my M1 MacBook Pro, Hook 3.4.2 is taking 70-75 of my CPU in the background.
Is this a known issue?
thanks

CPU usage can increase from time to time, e.g., when doing a big sync. However, it should not be persistent. Also please note that on multi-core processors, high CPU % numbers can be misleading. Is it slowing down your Mac?

It has persisted, so it does not appear to be associated with a needed large sync. Also, I am new to the app, so I have what I suspect is a paltry # of hooks.

E.g., this AM, it is still at 52-75%.

No, my Mac is not slow (I think). Frankly, this machine is so fast that I have trouble taxing the CPU. That said, I suppose there are tasks that could be affected, as could battery life. To put it in perspective, the next highest process at idle, Window Server, typically runs 20-29%.

FWIW, turning off iCloud sync in Hook had no effect.

Update: this high CPU use stopped spontaneously after several days on both my machines.

Thanks for reporting back. Sorry to hear the issue persisted, and glad it’s gone. If it happens again could you please take a process sample: How to Take a Process Sample of Hook with Activity Monitor app – Hook. That will enable us to see what is happening. Thank you.

I will do that. (Actually, I had sampled the process previously and scanned the result, but neglected to save it . . . oh well.)
best,
jason
