The packager (a.k.a. Combobulator)
You can package up your OBS scene collection along with optional deck, schedule and sound effects - then send it to someone else.
When you unpack on the target machine, you can then import the scene collection into OBS. A couple of things it doesn't handle yet are folders in vlc and slideshow sources. After import, you have to manually hook up your hardware like camera, capture devices, etc.
I packaged up my test scenes on Windows 10 then unpacked on Macbook - all working OK.
Since it's new, I would recommend exporting your scene collection from OBS as a backup - just to be safe. I'm pretty sure we'll find a few bugs, but working well so far.
