I know this issue is supposed to be fixed, but I am running latest Spine (3.6.48 Professional ; Launcher 3.6.46) and Undo/Redo doesn't seem to work. (I tried CMD+Z, CTRL+Z etc...)
Running on macOS High Sierra 10.13.1 (17B48)
As additional information, I am using a French keyboard (AZERTY), but I don't think that's related since pressing CMD+Q will quit the software as expected, CMD+N create a new project etc... just like a QWERTY keyboard.
Can't say when it stopped to work as I didn't use it much on mac before ๐
