Hi all, The underlying problem with headless mode in OS X seem to be that we always create a window, even when we run in the background, as we do in headless mode*. Marking the process as background only will remove the icon, menu etc. but it will not stop us from creating that window. Maybe I don't know enough about how Squeak/Pharo works right now but it looks like quite a lot of work to change this. And the code isn't pretty ;). Anyway I'd like to keep working on this but I've hit a wall. I can handle the Cocoa side but don't know anything about the VM's setup process etc. Could someone clarify this? Or maybe there are some docs? Also â What do you guys think about building a headless VM without any of the UI stuff in it? It might be simpler/cleaner than what we have now. All the best, Mark * Creating the window is almost the first thing we do! We do it before we know if we're running headlessâ¦
