I didn't try this for a long time, so I'm a bit baffled why it doesn't work because I'm sure I did it successfully before.
I have an external hard disk (USB C, but I don't think that matters), and I'm using Terminal to cd to it. In the MAME folder I created a MAME.ini file where I specified the individual folders full path:
But whatever system I want to start I always get the "Fatal error: Required files are missing, the machine cannot be run" error, but the ROMs I want to use check out ok in ClrMAME.
What am I doing wrong?
PS: I'm using v0.214 on macOS 10.14.6 with an executable name of MAME
