alt Hacker NewsI tried to set up a macOS VM recently so I could run an old version of iTunes to manage my iPods. I found it nearly impossible to even download an installer for older versions of the OS, and could never get it working. Where can one acquire an IPSW for, say, macOS Mojave? My understanding is this is not the same thing as the “Install macOS.app”?

For a version of macOS that old, you’d probably want a dmg, which you can create with createinstallmedia if you have the Install macOS.app. Not sure if it’s supported with Lume as it’s the first time I’ve heard of it.
I was trying to do something similar last year and gave up because it felt futile. That said, it was the push I needed to try Rockbox, and I haven't looked back. Managing things via the file system is really nice.
Mojave never was an IPSW, because it never ran on Apple Silicon. I imagine this tool might just not support that at all.
I like to use MIST (macOS Installer Super Tool) to grab old macOS versions: https://github.com/ninxsoft/Mist
Apple also provides instructions for downloading many older macOS versions via your terminal: https://support.apple.com/en-us/102662#terminal
