Hi @gad-imageinsight, can you clarify what you mean by the GUI does not open? Multipass does not have a full-blown GUI per say with a window that will appear. Instead, the GUI is a tray icon that should appear on the taskbar and will supply a few actions after single-clicking on it.

[gad-imageinsight]

Sure. I only had the icon in /Applications, not in my dock (if that's what you mean by "tray"), so I dragged it from /Applications and put it there too. But when I single-click it, nothing visibly happens. But I get a fresh crash report, so it was trying to do something, but failed. Nothing appears in the ,menu bar.

Are you able to utilize your instance, easygoing-owl? In the logs, it looks like the instance is failing to start. This looks like the likely cause of the GUI crashing.

[gad-imageinsight]

Well, I'm getting a start failed: cannot start VM without an image error on that, so, no. But I was seeing this behavior when it was working too. I've never gotten that icon to do anything. I deleted easygoing-owl and the crash still persists. I created a new image to be able to get some work done.

[sharder996]

Sorry, what I meant by the tray icon explanation is that after double-clicking on Multipass in /Applications is that an icon should appear in the upper right of your screen (in the place called the status menu, I believe). Then, single-clicking on this new icon should present a few Multipass commands.

However, I haven't been able to replicate the crash you're seeing. I only other idea I have on where it might be coming from is because your disk is formatted as case sensitive.

I seem to be having the same problem. Here is what I get when running multipass manually.

Other info / things on screen:

• The tray icon appears
• If I click it the context menu opens for a split second
• The crash mentioned above happens
• Interestingly: My Dock.app, which is set to "hidden" cannot be accessed anymore (when I move the mouse to the bottom of the screen the dock does not show), I think opening a different item in the tray makes everything work again.
