Unable to launch the Meta Trader 4 Forex trading app

Hi,

I downloaded Meta Trader 4 forex trading app from here - https://www.usgfx.com/mt4-forex-companies.

My iMac did not recognise the source so I had to override the security settings to allow installation from 'Anywhere' 9Using this command on Terminal : sudo spctl --master-disable). After successfully downloading the app I'm now unable to launch it. It says that the application is not responding.

Has anyone had similar experiences or know how to get i working?

Thank,

Sanjay
