Oh thats not good! Could you tell me your system specs, Ableton version and if you are trying to load the VST3 or AU?
I will pull out my 10.13 machine and test it today.
If you have a moment and could get me the error report I would really appreciate it:
When Ableton crashes it should show a crash report screen with a bunch of text (called a stacktrace). Either email it to contact@directmusic.me, send it in the MiniMeters Discord, or upload it to a pastebin and link it here.
