I use a 2017 iMac 5K with 32G memory and quad core and OBS is absolutely a lightweight for this one. Before, I was using a 2015 MBP and it was having a VERY hard time handling the streaming at 1080P (mind you I was running 2 screens off of it). I am not sure it's a hog because of bloat, it's just that you need a more than average computer to stream with good quality. Funny story is that once I clicked stop on the stream and it kept streaming. Showing me having a phone call, going on Facebook and just continuing with my day. I had to just shut down my computer because OBS would just not stop. On the new iMac I had absolutely zero issues with it and I am running it with 2 screens and 5K on the main screen.
