Cannot launch SafariDriver on Mac Sierra

Have tried to run on Mac 10.13.6 on Safari Version 11.1.2 with Katalon 5.5. It complains…

Please provide more details how do you execute Safari from Katalon Studio

Hi Vinh,

do I need to install web driver extension into Safari first?
I noticed that I only see chrome and Firefox in Web Recorder when I run Katalon on Mac 10. Do I need to enable Safari somewhere?

I also have done this step, it still didn’t work.
I copied the /usr/bin/safaridriver into /Applications/Katalon
