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:

Please download 4.8 from this link:

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