Cannot use the toolbar of Katalon Studio


I started to use Katalon (ver 5.4.1, macOS High Sierra 10.13) recently, but I encounter a problem. (downloaded by this link Katalon Studio Free Download | Katalon )
I can create/run test case/ test suits, check test report smoothly. But I cannot use the tool bar of Katalon Studio. As shown in the picture, the buttons in tab “File”, “Edit”, “Project”, “Debug”, “Window”, “Help” cannot be pressed. Only the tab “Katalon Studio” can work. Could anyone tell me how can I solve this or what I miss? Thank you!

Hi Jessica,

We already noted this.
Btw, you can workaround by click on the main window first then try again.

I tried your workaround but still cannot work.
Do you know when will the bug be fixed?
Thank you for your reply!

Hi Jessica,
This issue is a bug on macOS High Sierra 10.13 that causes many JAVA based applications get menu bar disabled. There are 2 options to fix this:

  1. Update your macOS to a higher version (recommended)
  2. In case you don’t want to update your macOS, follow these manual steps:
  • Right click on Katalon
  • Select Show Package Contents
  • Open Contents folder
  • Open Info.plist file
  • If opened with XCode, remove the entry for ‘Localizations’
  • If open with a Text Editor, remove the complete entry for ‘CFBundleLocalizations’

Hope this help
