PPSSPP black screen issue on Mac

[RushD2]

I did the same thing, switched to Vulcan on my iMac and now just the black screen when the program is launched. Copied the same file to my Mac Pro and it works fine, as the Backend setting is set reset to OpenGL??. Im guessing that a configuration file is written someplace on my drive but I have not been able to find it in the usual places IE: Application Support ....?

Any guidance would be appreciated
