I’m trying to set up DOSBox Staging on macOS to use a relative path in the .conf file for mounting, but so far none of the commands I’ve tried are working.

Currently, I’m running DOSBox Staging in portable mode, which means that I’m keeping everything self-contained within the application’s .app folder structure. I’ve copied my game data directly into this .app folder, and I’ve also placed the .conf file there. This setup allows DOSBox Staging to operate in portable mode, so it runs independently of system-wide configurations and keeps everything localized within the app’s directory.

My goal is to use relative paths in the .conf file to mount game folders from within this same .app structure, but I’m struggling to find a way that works.

Right now, I'm using absolute path names like this one:

mount c "/Volumes/Data/Games/The Ultimate Doom.app/Contents/MacOS/C/Doom_SE/"

The actual executable sits in the following directory: /Volumes/Data/Games/The Ultimate Doom.app/Contents/MacOS

But I can't point to this in relative terms...

Any advice or tips on how to make this setup work with relative paths in portable mode would be greatly appreciated! Thank you.
