<< Solved >> HD 620 problem in catalina - kernel panic

[diepeterpan]

Does sleep work?

My HD620 had a wake up problem on Catalina turns out to be a non clover Kext from /Library/Extentions and /Library/Application Support/VirtualBox to a backup folder and rebuilt the cache sudo kextcache -i, rebooted and now fixed.

I have same laptop Lenovo ideapad 320-14ikb I will share my working Hotpatch EFI folder
make sure install latest required kext in your system and clover bootloader
I uploaded VoodooI2C.kext no need Prevent Apple I2C kexts from attaching to I2C controllers, credit CoolStar patch
just install uploaded VoodoI2c.kext and put Hotpatch SSDT in ACPI/Ptached folder and use my config.plist
perfect working SSDT Hotpatch
or clean install macOS 10.14.6&macOS Catalina 10.15 with my EFI folder
enjoy

It works!!!! Thanks!!!!! You are a king!!

At first I saw your config and panicked because I saw that things were missing but I thought they were probably in SSDT ....
Only need to add the BrcmPatchRAM3 for the bluetooth

which one wifi card installed do you have?

I have a Dell 1560 BCM94352z

install these three kext on Catalina BrcmBluetoothInjector.kext+BrcmPatchRAM3.kext+BrcmFirmwareRepo.kext

do you have working my EFI Folder?
are you satisfy for my Hotpatch SSDT and config?
everything is working fine even micro sd card
I cleaned and optimized unnecessary file 10 days ago
worked perfectly

 

[Itay1778]

yes install VoodooTSCSync.kext

disable hibernatemode using terminal

sudo pmset -a hibernatemode 0 && sudo pmset proximitywake 0

How will sleep work if I cancel it from the terminal?

Hey @italy1778 ! Can you help me ?

I have the same issue on my Lenovo E470 (Intel HD 620) - the video is activated however, when I plug my HDMI cable a kernel panic happens.

What should I do?

Hi try to go over the solution they offered me here maybe it will work for you (because at the time it helped me) mainly while connecting HDMI.
