I'm surprised but happy! Nice one. Thanks for sharing what worked in case others run into this.

I don't think your issue is related to permissions. Did you get the crash like the original poster of this thread?

Does the web browser work? http://game.shadowera.com

Quite a lot changed in 2.9050, but it was chiefly the update to Unity 5.0. That may well be incompatible with your machine. How old is your Mac and what's the graphics card?

Oh, that's good to hear. I'm not on Yosemite myself yet, so didn't know for sure!

Have you tried going to here: /Users/USER/Library/Application Support/com.wulven.shadoweralauncher

Then right-click Open on Shadow Era.app?

I think Yosemite is picky about running non-signed...
