Hi, 

I'm trying to run Selenium Web driver tests using appium and getting following error on Mac.

What version of Appium? And what command are you running when this error happens?

Hi,

Selenium version 2.40.0 and appium is 1.1.0 and it's failing when trying to connect to appium, her is the exception on selenium side.

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

[Isaac Murchie]

This does not look like an Appium log. Can you send the entire Appium server log?

This has been reported, and is being investigated.

Hi Isaac,

Thanks for your support.

 don't now if it will help or not, but for me everything works fine when I'm passing  package and launcher activity to appium

capabilities.setCapability("appPackage", "com.package");

capabilities.setCapability("appActivity",".RootActivity");
