Hi I have Dell Optiplex 3050 I have followed numerous guide to install High Seirra. I have managed to get to the installer, Intel HD 530 showing with full acceleration, ethernet en0, imessage works, Power Management works fine. What does not work is 4k ( i have connected to 4k TV using display port 1.2 I have also tried high speed hdmi cable), HDMI Audio and Onboard Audio.
I believe lot of you got succeed on 3040 would someone here mind creating A to Z guide with requiring files to get me up and running. I guess 3040 is similar to 3050. I love to start from scratch once again as you guys have slightly diff setup to clover usb than mine. I hope some one shed some light on me.
Thanks
Shania
