Error in Launching Chrome Browser in Real device from Mac Machine

I am automating a Mobile Web which I have test on Chrome Browser in Android Real Device.

Machine settings :
MAC OS : 10.9.5 (Yosemite)
Appium : 1.4.8 (Draco)
Browser : Chrome v-50
Chrome Driver : v-2.22
Mobile : Samsung Galaxy Tab

Below is my Capabilities
capabilities.setCapability(MobileCapabilityType.BROWSER_NAME, “Chrome”);
capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, “Android”);
capabilities.setCapability(MobileCapabilityType.VERSION, “4.4”);
capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, “Samsung Galaxy Tab”);

When I try to execute the scripts it open up in-Build Browser ( and not proceeding further.

The same Device and with same settings working fine in Windows Machine. It open up the Chrome bowser and execute the scripts.

Please help me on fixing this.

Any update on this.

Hm, looks like it could be a bug. Can you post this as an issue to the github project for appium?
