Answered Matter Control locks up under macOS High Sierra

So I have a problem with Matter Control under High Sierra. I launch the application and I see the icon in the dock and thats it. I never see the interface to it. I have to force quit it.

On this same machine under Sierra it worked fine.


I checked the software downloads and I already have the most recent version of Matter Control.

Is this something that can be fixed? I liked the simplicity of Matter Control.


Thanks!

Ahhhh! Thanks for that. I didn’t realize it wasn’t a robo3d specific software.

What other software is everyone using?

I have a r1+Plus

 

If it were me, I'd use Finder to find the executable and run that from a Terminal session to watch why it failed (console-logged progress).

Applications -> right-mouse click on MatterControl -> Show Package Contents -> Contents -> MacOS -> run MatterControlMac

You could alternately do this in a Terminal session instead by running:

$ /Applications/MatterControl.app/Contents/MacOS/MatterControlMac

A likely culprit is the default rights in the folder /Users/myusername/.local/share

You might need to change Everyone to Read & Write.



It sounds like someone at Apple thinks that they need to tighten up overall security and version after version has been ratcheting that up. If MatterControl is an unsigned app then OS X probably wants to put it in a playpen and run it as a user-who-isn't-you. It's a subtle security-ish sort of way of strong-arming developers so that they have to buy a $100/year digital certificate and part of Apple's way of extorting money wherever they can, all in the name of security.
