I have tried about a thousand times now to download the desktop client for Mac and every single time, when I go to open the app, it crashes. I have never been able to open it, even once. I have no other problems with running anything else on my macbook. My software is fully updated at OSX 10.9.5. Please help! I have uninstalled and reinstalled, rebooted my computer, tried everything that I could think of and still the app crashes every time I try and open it.
