Texture problem on Mac

I’ve been getting this weird problem lately on my Macbook and version 4.11.2 where textures aren’t loading for materials. Anyone know a possible cause or solution? This happens all the time whenever any content is imported into the editor. Doesn’t matter if they’ve just been imported into the editor or the project has been opened. Nothing changes when I apply the material to an object either, just the default grid texture.

Thanks for any input you guys may have :slight_smile:
