Hello, i m having some issue with the video and USB. by using Jake Lo boot pack i was able to install Catalina 10.15.4. after the install i m getting [IGPU] Hash data from ME never returned, status = 1, doing retry#, to resolve this i had added boot args -disablegfxfirm
i have added dell PCIe wifi card with DW1820A at slot one, there is a cable connecting the PCIe card to the onboard USB port for bluetooth, but i m not able to detect any bluetooth device. i have tested with windows and it's working just fine. also when i dismount a USB drive. look like others USB port become un useable.
Bios: 1.15.5
Clover revision: r5115
Catalina 10.15.4
Whats working:
Speaker (Internal)
Internal USB port (HS12) it was disable from the bootpack
Wifi (DW1820A)
Bluetooth
Handoff
Whats NOT working:
Sleep (Screen stay black after wake) pending to add a video card
Hotspot from Iphone. i do see my phone listed under wifi icon, but i can't connect to it. not looking to resolve this
edit:
Want to upload my work for others too just incase someone building one, i used Jake Lo bootpack from this POST to make my USB boot drive. updated all the kext and USB port mapping for internal port for Wifi. all credit go to the site and Jake Lo
