What about the new release of Katalon? the release of 5.3.0 is not able to open the error org.openqa.selenium.SessionNotCreatedException.
And i have enabled Remote Automation in Safari browser and the Safari browser is also installed.
Safari browser version: 11.0.3

Have you installed the extension? Or maybe show me the full message of its. I’ve no problems here using Safari latest version

Hi Vinh,

I am using Win 10 and safari 5.1.7 however still facing issue in opening browser. Can you tell me whether any extension is required for Windows too and from where i can get it.
Below is the log when i tried with safari:

Unable to open browser with url: ‘’ (Root cause: org.openqa.selenium.WebDriverException: SafariDriver requires Safari 10 running on OSX El Capitan or greater.

The same test is running fine on Chrome and FF.
Also not able to open Microsoft Edge, Log:

(Root cause: org.openqa.selenium.WebDriverException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:38415 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect

Kindly Help.

Thank you,
Shruti
