Replace Config and ACPI folder. Add attached kexts to /EFI/Clover/kexts/Other to enable your SDCard reader 3350-FixBlankScreen.zip

@rjjd Give this a try with latest Catalina Install following Clover guide, use attached files as bootpack. Goes into /EFI/Clover replacing the old LenovoP1.zip

Launch Disk Utility. Select Show all devices from top left dropdown. Format to GUID / External Journaled

Wifi only shows up under Network/Wifi in Sys Info, not Ethernet card, but Yes, strange that it works OOB on Catalina. I'll have to take a look at the "FixAirport" patch. Update: Hmm, perhaps 10.15.5 add back support for BCM4352 (14e4:43b1) aka DW1550. Only need to add FakePCIID and FakePCIID_Broadcom_Wifi. No need for FixAirport patch either for the WIFI.

ok, try this local version gen_debug_local.sh.zip

See here to enable 4K display, same settings and values for OC as Clover For OC, it's under DeviceProperties/Add/PciRoot(0x0)/Pci(0x2,0x0)

See update here Test to work with 2K display, but 4K should work too. I don't have 2K display to test. Confirm if 4K works for you.

Enabling 4K External Display I had been seeing some queries about enabling 4K display for E7440 lately so I decided to spend some time on the matter. Unfortunately I don't own or have access to a 4K display but I do have a 2K display to test with. As expected the default settings can only display as high as 1080p. I did some experiments following existing guides found here in the forum and was successful getting 2K to display, I believe it should work for 4K as well. So here are the steps required: 1) Raise the DVMT pre-alloc from 32mb(default on this model) to 128MB in the BIOS. Since you can't access this setting from Dell's BIOS, you'll need to use the EFI shell to accomplish this. See my guide here. Below are the locations found for DVMT Pre-allocated and CFG Lock Set DVMT @ 0x255 to 0x4 Set CFG Lock @ 0xC8B to 0x0 (not sure if this necessary, but it didn't break anything) Here are the commands from EFI Shell: setup_var 0x255 0x4 setup_var 0xC8B 0x0 2) Update Config.plist file from bootpack above under Devices/Properties/PciRoot(0x0)/Pci(0x2,0x0) the following: framebuffer-cursormem = 00000003 framebuffer-fbmem = 00000003 framebuffer-stolenmem = 00000008 uncomment #framebuffer-unifiedmem by removing the # in front (Optional) That's it. FYI, the DVMT & CFGLock value will restore to default if you ever select Load Default in the BIOS. You'll need to redo the steps in #1 Updating BIOS does not remove the settings.

1) Make sure you don't have other VoodooPS2* kext anywhere else.../L/E, /S/L/E, EFI/Clover/kexts/10.* 2) You can't find the /Library/Extensions folder? Try holding Shift+Alt+. (that's a period in case you don't see it, this will enable all hidden folders) 3) try adding to boot arg darkwake=0

Here, run this instead Might need to run this first if script won't start sudo chmod a+x gen_debug2.sh Pre-requisite, boot to Clover, Press F4 and F2 to generate some data Then the script will run successfully gen_debug2.sh.zip

best to post a screenshot. The last message might not be the issue

Make sure to follow the last post of the thread regarding Catalina.

post debug file while HDMI is connected

Try different USB ports. Update Clover to latest version. You might want to update all the kexts as well.

You can add your specs to a signature file by editing your profile or just post it in your 1st post. What keyboard do you have, did you select ISO or ANSI format? Post a pix of your keyboard

You never mention or add your system's full specs so not sure what you have. If it's an Intel (most likely), it's not really supported yet but there are a few in developement. Here's a link to some discussion. For now, you could try replacing it with a supported device, ie DW1560, DW1830 or DW1820A. See our list of supported/ unsupported devices in the R&D section. I would recommend not to go for any Atheros as Catalina had dropped support for them.

try adding to boot arg -disablegfxfirmware

USB issue. Try replacing USBPorts.kext with this one USBPorts.kext.zip

Here's the files if you got it booted Mojave _IO80211Family*.zip

You can remove the following kexts: AppleIGB AtherosE2200Ethernet RealtekRTL8111 AHCI_Intel_Generic_SATA FakePCIID As for touchpad, you currently using ApplePS2Controller.kext which is a generic mouse kext but it does give you some gestures. You can scroll with 2 fingers up and down. You can tap to drag, 2 fingers tap to right click. The only issue it has is that you'll have to tap twice to enable CapsLock and twice to release or thrice to enable and 1 to release. "No touchpad found" is find, there's nothing you can adjust to make it any better. This system has an Alps touchpad, so if you're using Rehabman or acidanthera's VoodooPS2Controller or Dinesh's ApplePS2Smarttouchpad, they are for Synaptics touchpad mainly. You need to go with Dr. Hurt's version of VoodooPS2Controller which is developed for Alps. With that said, you can try VoodooPS2ControllerR6.kext compiled by Bronxteck, but it's not fully supporting v7 of Alps. You might have to tweak the fingerZ a little to your liking. But even with this Alps kext, you'll still have the same basic gestures as ApplePS2Controller. The CapsLock is fixed and you'll have side scrolling as well and it'll show up in touchpad preference. Most the functions you see in the preference pane won't work, so don't expect anything more.

post your Clover folder

If you're installing Catalina, make you have Clover v5107 at minimum. When using the bootpack, make sure the contents of the zip are extracted into /EFI/Clover. Boot with -v debug=0x100 -igfxvesa If booted, continue using the same arg until installation is completed Back to your Windows format, check if it's MBR. If it is, you'll need to convert it to GUID. I'm not sure if it's possible. I never had to do it before I had always install MacOS, then Windows.

For 10.15.3, I think I only replace IO80211Family.kext But I had to replace also IO80211FamilyV2.kext for 10.15.4 and after.
