I have a MacMini (Mac OS Sonoma 14.2.1). I don't know what happened, X2go client worked perfectly but at some point it even fails to open. I launch it from my Dock, the window appears for a fraction of a second then disappears; I can still see the X2go client Menu toolbar but after I click on it once it disappears too. I tried to uninstall and re-install X2go client but this did not fix the problem.
