I've started to get this prompt come up every time I opened IntelliJ: Do you want the application 'IntelliJ IDEA 14 CE.app' to accept incoming network connections?. This happened after doing an automatic update within IntelliJ itself. After a bit of messing around, I was able to come up with a solution to make this prompt disappear.

I checked the Security & Privacy settings, and IntelliJ was listed as allowed to accept incoming network connections there.

This is what I ended up doing. Open the Terminal.app and type in the text below. Make sure that IntelliJ is not running while you do this.
sudo codesign --force --deep --sign - /Applications/IntelliJ\ IDEA\ 14\ CE.app/

This will re-sign the app and the prompt will disappear. Note: You will get the prompt one more time after doing this, however it won't come up the next time.

You will see something like this in the terminal:
/Applications/IntelliJ IDEA 14 CE.app/: replacing existing signature
