> OBS was a driving factor

Why? OBS runs on macOS too

It runs horribly on macOS. Like a night and day difference. If I understand correctly the difference is primarily regarding the encoder.

I also switched my streaming machine over to windows recently.

Edit: ok, “horrible” is dramatic, but it was honestly shocking the first time I booted into windows and gave OBS a try there. Exact same computer that struggled with OBS in macOS produced a much better output without breaking a sweat.

Using Boot Camp or a Hackintosh to be able to do that on the same computer? Might help to make the distinction between it overperforming via Boot Camp or underperforming on a Hackintosh.

Over-performing via Bootcamp. The machine is a fairly new Mac Mini.

Beside horrible, it's terrible, Just upgraded and can't even resize the panes. And the CPU usage is high even when not streaming or do any capture etc.

Huh. Happy OBS macOS user here.

I guess YMMV. Used OBS a couple of times on macOS and was impressed with how smooth it ran.

Yeah, this is news to me too - we’ve been using it on a Mini (granted, it’s an i7 - but still, it’s a laptop in an aluminum case) with zero issues. Integrating NDI, no less!

What version of OS X are you running? What GPU do you have?

Do you do any picture-in-picture of other apps with heavy CPU utilization, or apply any filters (chroma key/crop) or animated overlays? Multiple cameras or input sources? Multiple audio sources?

The framerate was terrible, the entire machine would lag, and the audio would constantly glitch out at best. Saved recordings were unwatchable.

I tried tweaking everything with the process priorities in OBS and the other apps, and could never get an acceptable result. AMD ThinkPad worked out of the box, did everything I described above, and CPU utilization stayed around 2-3%, and I couldn't even notice it was running while using other apps. All of this while I had it hooked up to extend the desktop onto 3 monitors. Streams and recordings are flawless.

"horrible" is not dramatic.... it was unusable.
