I downloaded pycharm on mac osx el capitan operating system. It froze as soon as I opened up a project. I couldn't type anything, and I couldn't force close pycharm. I had to force shutdown my computer, because it wouldn't restart with pycharm open. I deleted pycharm and downloaded the latest version, and the same thing happened. I removed all unused plugins and the same thing happened. I have intellij and webstorm on my computer, and they work fine. pycharm is the first app that I have downloaded on my computer to do this.
