I’m starting to try using HammerSpoon, which is driven by Lua, for automatically arranging my applications depending on application scenarios.
I have 3 screens, including a MacBook Pro at Retina native resolution and a Seiki 4K display. I grabbed the names of the monitors from Display Menu‘s menu bar menu.
I initially made the mistake of looking for “Outlook”, “OneNote”, and “Chrome”, but all three applications require their respective company’s names to be included in the application name.
