Possible you need Glade, but you use macOS and won't change your OS or use any virtual machine. You can install Glade on your macOS using Homebrew. Three simple steps:
Open a Terminal.
Enter a first command: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
It will download and install Homebrew on your macOS.
Note, you should be enter your admin password two or three time during that process.
After end of Homebrew installing enter a second command: brew install glade.
So now you can start Glade with command glade in the Terminal.
