I have some strange behaviors with MOI 3.1 on OS X. I am using an iMac 5K late 2015 in its highest configuration with two extra monitors.

When pushing the Moi window to one of the extra monitors and then go to full screen mode with Moi, the Moi window sometimes disappears.

When trying to export something, often the export-window is under the Moi main window but I am unable to bring the export windows to the front.

Hi Blade - it has to do with the multiple monitors. The "Wineskin" system that the MoI Mac version currently uses has not yet caught up to changes in how multiple monitors work in recent Mac OS versions.

There is a system setting that you can change to go back to the previous style OS multi-monitor behavior which should then make MoI work ok. That setting is under System Preferences > Mission Control - uncheck "Displays have separate Spaces" there. You will then need to reboot your system in order for this change to take effect.

This should be fixed up better in MoI v4 which will not use the wineskin mechanism anymore, but it will still be a while yet before v4 is ready.

Hopefully Wine will fix this bug sooner rather than later. :-)

Out of curiosity, is MoI for OSX essentially a Windows version wrapped in Wineskin or are there any significant differences in the build?

Hi Jacob,


> Hopefully Wine will fix this bug sooner rather than later. :-)

The bug is actually in the XQuartz layer, not in Wine. It does not look like it will be fixed anytime soon here are some bug reports about it:
https://xquartz.macosforge.org/trac/ticket/797
https://xquartz.macosforge.org/trac/ticket/796
https://xquartz.macosforge.org/trac/ticket/817

But I expect it to be solved in MoI v4 since it won't use XQuartz anymore.

For the most part it's the windows version wrapped in Wineskin, but there is also some native code integration for a few key areas like showing the file open dialog and getting multitouch events.

I am working on changing this for MoI v4 though, so that v4 will be a native compiled version on OS X and Wineskin won't be used anymore. This involves a whole lot of work though and is still in progress.

The file I downloaded from http://moi3d.com/reinstall.htm is Version 3.0 Sep-18-2014. Is version 3.1 just for macs?

Yes, version 3.1 is only for Macs, it has changes to support the new "El Capitan" operating system that just came out.

The version 3.0 that you downloaded is the current version for Windows.
