Hmm, after deletion of ~/Library/Applications Support/GIMP/2.10 and start of Gimp-2.10 all necessary folder should be created, hence no handmade folder creation!
Download the latest plugin built! The content of this tgz file including the GMIC folder has to be copied into …/plug-ins/
My next step would be to start gimp from terminal to get the log during start:
In Terminal type
/Applications/GIMP-2.10.app/Contents/MacOS/gimp
and look where the plugin crashes

Apparently this new user can only create a limited amount replies on his first day. I’m sorry for my late response…
So… in Terminal for the first line:
ls: Support/GIMP/2.10/plug-ins/”: No such file or directory
ls: “~/Library/Application: No such file or directory
For the second line:
ls: Support/GIMP/2.10/plug-ins/”: No such file or directory
ls: “/Users/youraccount/Library/Application: No such file or directory
Terminal use can be tricky. Still how did you manage to copy the plugin into the hidden folder Library?
Lets try without Terminal:
Open Finder Menu Goto…-> Entry Goto Folder… and type “~/Library”! (tilde ~ is “Option N”, backslash \ is “Option Shift 7” not necessary here, at least on my keyboard)
Open “Application Support → GIMP → 2.10 → plug-ins” by clicking and tell me what is there stored! That is the place to copy the unpacked content of the gmic plugin tgz file! (listed in an earlier mail)
If you add in the gimp preferences the folder “~/Library/Application\ Support/GIMP/2.10/plug-ins/”, it is either only possible if existing or it is marked red. Hence there is the folder and you are looking at some other place. Maybe you should understand that “~” is a shortcut of “/Users/youraccountname”, this means not literally youraccountname but YOUR USER ACCOUNT NAME on your machine!
I assume the first line in the gimp preferences is not marked green! Please try to print exactly “/Users/youraccountname/Library/Application\ Support/GIMP/2.10/plug-ins/” After that restart gimp and look at the location! In any case Gimp will create this folder hierarchy, except your Gimp is running as a different user! I think you don’t know how to do that!?
What I do know is that I’ve just created a plug-in folder (I did the same thing for the brushes, gradients, palettes and scripts folders; as they were also absent in Gimp 2.10) and now GMIC is in the filters list. I opened an image and clicked the GMIC-Qt, but only the GMIC-symbol (Hat and magic wand) appears in the Mac dock appears.
I’m guessing there is something wrong with the plug-in.
Ok I don’t know what is with your system, still seeing gmic means nice progress. What still lacks is most probably X11! You have to install XQuartz from https://www.xquartz.org!
For some interactive functions X11 is necessary for gmic and hence linked in!
XQuartz does not support dual monitors. Believe me I’ve tried. And besides, GMIC running under Gimp 2.8 worked fine on my system. It would be nice if someone could solve the problem.
Tscha, for the gmic preview dual monitor is not really necessary, I have also two. Still for the plugin is X11 a must or you build it by yourself. By the way, GIMP does not use X11, only the plugin in certain circumstances. Where is the problem to have XQuartz installed (and started during gmic usage)?
By the way, as far as I know the Partha plugin build does not have X11 linked, therefor no interactive functions are possible, like the newest x_warp …
