d620osx Posted October 18, 2019 Share Posted October 18, 2019 Hi I have a HP8200 i5 with a GT210 GPU which has been working fine with on Sierra. I have managed to update to Mojave with the help form forum members. Now want to try an upgrade to Catalina, as I have had to go the unsupported route to upgrade to Mojave, what is the best way to upgrade to Catalina as part from the dosdude method. Thank you Link to comment https://www.insanelymac.com/forum/topic/340789-hp8200-upgrade-to-catalina/ Share on other sites More sharing options...
d620osx Posted October 18, 2019 Author Share Posted October 18, 2019 Thank you for replying. I presume I need to do something in the DSDT for Embedded Controller ACPI? Will search for what I need to do with the GPU as an alternative, what do I need to upgrade to please?
