Tangra Posted August 5, 2020 Share Posted August 5, 2020 Hi all,I could install Catalina on my legacy Laptop MSI GX700, patched the Video with Quartz Extreme etc so the laptop runs perfectly with Catalina.I have a weird issue during Shut Down or Restart. The machine does not restart or shutdown hanging in back screen and I have to forceshut down it via the Power button. It works but after several bad shutdowns the computer does not boot into Catalina anymore.Obviously the restart problem destroys the catches or something like that.Is there any Shut Down/Restart patch I can try?Thanks Link to comment https://www.insanelymac.com/forum/topic/344764-restart-and-shut-down-problems/ Share on other sites More sharing options...
