How do I edit the text (wrong formatting used for pre-formatted text)

Looks like the call that failed is 10.10+, and you're on 10.9....

​https://developer.apple.com/documentation/appkit/nsgraphicscontext/1535380-graphicscontextwithcgcontext

You can try to fix this one call to it's <10.10 equivalent , but you may well find there are more 10.10+ calls if you have found one...

It would seem that OBS.app is not using the Qt from MacPorts (/Applications/OBS.app/Contents/Resources/bin/QtCore).
As you can imagine, it is only possible for us to support the Qt installation that we have control over.
You might have better luck contacting the developers of OBS.app.
As noted by kencu, a good starting point might be the fact that OBS.app is trying to call a 10.10+ method.
