Can't open IntelliJ on MacOs

Please reinstall from the .dmg at http://www.jetbrains.com/idea/download/index.html.

Unfortunately it wouldn't fix the problem

Try running from the Terminal:

/Applications/IntelliJ\ IDEA.app/Contents/MacOS/idea

What error do you see?

/Applications/IntelliJ\ IDEA.app/Contents/MacOS/idea

Seems like I've set a wrong JVM flag ;)

So, the issue is caused by the invalid JVM option inside /Users/ohad/Library/Preferences/IntelliJIdea2016.3/idea.vmoptions file.

Please fix it.

Now it wouldn't respond to my editing.

Even though I have edited

/Applications/IntelliJ\ IDEA.app/Contents/bin/idea.vmoptions

The app still would not open with the same error message.

You have edited the wrong file, please edit 

/Users/ohad/Library/Preferences/IntelliJIdea2016.3/idea.vmoptions

Great! it works now.

I have uploaded my logs, in case you are curious.

Big thanks Serge!!

Mahades-MacBook-Pro:~ mahadejhonny$ /Applications/IntelliJ\ IDEA.app/Contents/MacOS/idea

-bash: /Applications/IntelliJ IDEA.app/Contents/MacOS/idea: No such file or directory

I can't open it

Do you use IntelliJ IDEA Community or Ultimate? Did you install it from the .dmg or via https://www.jetbrains.com/toolbox/app/ ?

Idea Community

The path for IntelliJ IDEA Community on macOS would be /Applications/IntelliJ\ IDEA\ CE.app/Contents/MacOS/idea if it was installed from the .dmg.

hey serge

thanks

/Applications/IntelliJ\ IDEA.app/Contents/MacOS/idea

Your question is already answered above:

"did not work" is not very informative.

Would you please be so kind to post the errors you've got? What IDE version did you install? Where did you install it from?

/Applications/IntelliJ\ IDEA\ CE.app/Contents/MacOS/idea

I was installed from official website

and intellij IDEA CE version

Any errors in the Terminal? Please attach the screenshot. What macOS version do you have?
