Sent Katalon_Studio.dmg with version 4.8

Hi everybody, I’m having problem with Safari 11. Who has file Katalon_studio.dmg with version 4.8 or lower, please send to me through my email: sara18lucky@gmail.com
Thanks.

Please download 4.8 from this link: http://download.katalon.com/4.8.0/Katalon_Studio.dmg

And by the way for your current question: Katalon Studio only supports Safari 9, any Safari version beyond that is not supported yet
