Hi. Well, I gained access to a different computer here that is running my Maya scene fine. Coincidentally it is also a Mac, but it works as well as my Work PC back home, so all's well that ends well.

Just to follow up the last response, I had already optimized and deleted history. For whatever reason, there was just not going to be any getting around whatever the compatibility issues were with that MacMini.

Thanks, everyone.

Best, T
