Why would 3D project only crash on play, MAC?

I’ve submitted a bug report but I thought I might also get some answers if I ask a question here too.

If I start a new 3D project and add anything to the scene and press play, Unity Editor hangs forever and requires a force-quit. If I have an empty stage it works fine. If I select a 2D project, everything is fine.

There are no scripts attached to anything. This is a blank project with only a cube in the centre of the stage. When I hit play, unity freezes.

Everything is fine with a 2D project though. This only occurs with 3D.

The editor log does not appear to offer anything else that suggests an infinite loop or memory leak.

I’m really asking in case this has occurred to anyone else and they have any ideas about a solution. It’s quite frustrating.

I am running OSX 10.9.5 on a MacBook Pro (mid 2014).

Many thanks

If you have this problem upgrade your OS. I’m now on 10.12.3 and no more problems. Unfortunately I wasn’t allowed to upgrade my OS without the “help” of the IT department at work in case I somehow deleted the internet instead of pressing the Update Now button.

It’s done now, and I haven’t had any problems since.
