Rust bug since new update? (MAC)

Ever since the new update for Rust, I can’t get past the grey Facepunch logo that displays after the Unity config menu(?) Has anyone else on mac experienced this bug?

System specs:

late 2011 macbook pro running mavericks

2.8ghz i7 core
8gb 1333 mhz ddr3
intel hd graphics 3000 512mb

I have tried reinstalling it, didn’t fix it.

I’m not opted in to the dev branch, either.
