I've started to play around with the extremely versatile swiftDialog tool. One of the things that I'm finding most interesting is the ability to provide a progress bar based on contents of a command file. I've started to think through how this could be used for a scripted macOS upgrade. It should be easy enough to read from the startosinstall.log file into whatever command file is being used, and the text is fairly predictable throughout. That said, I'm still new to it and learning how to make best use of it.
Has anyone already built out a script to display the startosinstall progress via swiftDialog?
