Perforce integration error

Hi, 

I am trying to integrate perforce VCS with intellij 14 (Mac OS X El Capitan).

In the Preferences -> Version Control -> Perforce page I have set the location to my p4v client in my Applications directory. Path to p4 executable: p4 to path as per the which p4 command (/usr/local/bin/p4).

When I try to connect I get the error:

   Cannot Connect to the Perforce Server

   Cannot run program "p4" (in directory "/MainFolder/") error=2, No such file or directory

Intellij is trying to run p4 from the /MainFolder/p4. I have placed the p4 in intellij expected path with all access permissions but still the same error.

Similar, question can be found on stackoverflow which gives more detailed information.
