Moderators Jake Lo Posted March 5, 2022 Moderators Share Posted March 5, 2022 Graphics issue. It doesn't look like you're using the same file as the OP attached. Your error shows you're using Macmini8,1 The OP attachment shows iMac17,1 Link to comment Share on other sites More sharing options...

Administrators Hervé Posted March 6, 2022 Administrators Share Posted March 6, 2022 Please check and post your system’s specs because: nVidia Quadro K620 is Maxwell and therefore unsupported beyond High Sierra (with which it requires the nVidia Web Driver). Intel HD500 graphics is a low-end mobile iGPU of low-end Apollo Lake SOC platforms and unsupported under macOS. It cannot be what’s fitted to a Skylake workstation such as the Precision Tower 3620. 'should be something more like Intel HD530 (i3/i5/i7 Skylake CPU) or HD P530 (Xeon E3-12xx v5 Skylake CPU).  Once you know what hardware you have, which is a pre-requisite, you may consult this thread: https://osxlatitude.com/forums/topic/8238-supportedunsupported-gpus-graphics-cards  Link to comment Share on other sites More sharing options...
