Hi Michael
Re: The commands appdata folder for Mac is at ~/Library/Application Support/Moi/commands . I recommend to put them in there.

Ok not quite sure where theses scripts go in V4 Moi on a Mac OS-10.14.6 been hunting for a while now
I cannot find application support or appdata within MOI folders - I can find an Application Support folder on the MAC by doing a whole computer search, but it is empty - apologies not that Techy so its not 100% clear where the scripts should go.
