Hi Guy, others are able to run MoI ok on Mavericks so it's not just a general problem, there's something that's going wrong on your machine specifically. It's unfortunately hard to narrow such issues down when they are not able to be reproduced over here...

Are you running any low level system utilities like Haxies or virus checkers? If so you might try temporarily disabling those and see if that has any effect.

Is it possible that you have any different from default permissions set on your /tmp folder? If you do then that can cause problems with MoI.


Another thing you can try is to install the latest version of XQuartz from here: http://xquartz.macosforge.org/landing/ then set MoI to use that system installed XQuartz instead of the one that’s bundled along with it.

To change the setting in MoI to use system XQuartz, do that same right-click on the .app and run Wineskin.app thing, then on the dialog again push the “Advanced” button and then on the next dialog go to the Options tab. Then the settings to mess with are the bottom 2 checkboxes on that page - uncheck the "use wrapper's quartz-wm" one and check the "use system Xquartz" and see if that makes any difference.

Thanks,
- Michael
