It sounds like the Metal RenderSystem didn't get loaded at all. Is there an Ogre.log generated? Could you upload it?

Hi thanks! And the same is happening with the plugins.cfg file (which tells which plugins to load and their locations, including RenderSystems) It couldn't find it so no RenderSystems loaded...

We provide [some helpers](https://github.com/OGRECave/ogre-next/blob/master/OgreMain/include/OSX/macUtils.h) which should help you on this issue ([source code](https://github.com/OGRECave/ogre-next/blob/master/OgreMain/src/OSX/macUtils.mm))

Ah! Thanks! Are you able to submit your changes to get Tutorial 00 to this stage? That'd make my work easier to check this issue

Either a diff or pull request. If you think the changes aren't good enough (ie. has some hardcoded stuff) posting a patch here is fine

OK I took a look at the sample. I [pushed a fix for the initial crashes](https://github.com/OGRECave/ogre-next/commit/657136b00f688251ea789d7cac1b1a1a8a0b7899) you found. However I got to the same point as you (the app "freezes"...
