Hi, I saw an old thread about Undo not working on OS X, and it just happened to me on 3.7.94 Pro.
I don't think it's the hotkeys or keyboard layout, since I see the undo arrows blink when I press Cmd-Z or Shift-Cmd-Z. But even if I click the arrows, the undo is not working.
This was only a test I was trying out, but if it was a real project it would be pretty horrible if this happened. Check the video for what it looks like:

After restarting Spine, Undo works as it should, but why does it happen?
Thanks!
