Hi Kevin,
One of the first things you can do is see if the device is recognized by command line tools outside of Xcode:
idevice_id -l
If that does show your device, then it could be that you don’t have permissions to run some of the other command line tools that Katalon (and Appium behind the scenes) require. You can reinstall those tools with:
brew uninstall ideviceinstallerbrew uninstall libimobiledevice uninstall libplist
brew install --HEAD libplist
brew install --HEAD libimobiledevice
brew link --overwrite libimobiledevice
brew install --HEAD ideviceinstaller
brew link --overwrite ideviceinstaller
sudo chmod -R 777 /var/db/lockdown/
Hope this helps,
Chris
[EDIT] Included reference to reinstall libplist, too, thanks to: Real iOS device shows up as <unrecognized device> . the execution fails because of a desired capabilities being blank
