I just noticed this in the last week. I don’t know if it directly aligns with the update or not (It could very well align with a “cleanup” I did on the machine… repairing permissions and clearing cache’s and such)
Sonarr on my Mac (Running Yosemite, all the way up to date) seems to be reading crazy amounts off my disk.
I had it up and running for about a week and it read almost 12TB of data.
The whole machine is slow. The minute I shut down Sonarr, it’s usable again.
Fire it back up and it slows down again.
First time posting here, so tell me what logs and such I need and I’l get them for you.
