It shouldn't take that long, usually 20 -50 secs at most. Try resetting BIOS to default, apply and then go back to reset to enable UEFI/ AHCI/ Disable secure boot

You mean it doesn't auto switch from headphone to internal speakers? Try adding CodecCommander if you haven't already and install alc_fix See here

OSID rename must go before XOSI and your missing the rename of BRT6 Need to add patch BRT6 to BRTX or whatever letter you want to change it to as long as it's not already used in the DSDT

You need to determine which port is your HDMI. In the 1st patch, you have con1, 2, and 3 set to HDMI. If you could post an IOReg file with the 1st config file, we could help you patch it to your 2nd config Use IORegistryExplorer.app v2.1, export, compress and attach it here. By the way, it would help even further if you could post the full system specs so no guessing game needed.

Make sure you have UEFI and AHCI enabled in the BIOS. Raid is not supported.

Disable the wifi (airportitlwm) for now until you have it installed. Use the ethernet instead

Awesome job on the battery hot patch. Give this a try. You'll need to add a rename of _WAK to XWAK to your Config file SSDT-WiFi-LED.aml.zip

Can you post your Battery patch?

You can try generating SSDT-PM.aml from SSDT-Prgen.sh but remove SSDT-PLUG.aml.

I think you need to add it to _ini as well

here's 2 versions for RealtekRTL8111 2.2 and 2.4 As for Wireless, your card is not supported as Hervé mentioned, you'll need to get it physically replaced See here for a list of supported M.2 wireless device https://osxlatitude.com/forums/topic/12972-macos-compatible-m2-cards/ https://osxlatitude.com/forums/topic/11138-inventory-of-supportedunsupported-wireless-cards-2-sierra-big-sur/ realtekRTL8111.zip

FYI, you shouldn't be mixing different versions of OC files. Your OpenCore.efi, CleanNvram.efi, BOOTx64.efi, Bootstrap.efi, OpenCanopy.efi are all from different dates.

I didn't make any adjustment to the kext section but you could try disabling SMCDellSensors.kext. Known to disable touchpad for some reason.

Try this, completely hot patched without DSDT Add SDCard Reader Added Fn keys for Brightness Enable audio with IRQ fix Replace the Config and ACPI folder. I see your USB Ports have some discrepancy. You have USBPorts and USBInjectAll + SSDT-UIAC.aml and Port limit patch in the Config file under Kernel. USBPorts. kext won't work since it's hardcoded to MBP11,1, and your SMBIOS is set to MBP11,2, but not sure between SSDT-UIAC and port limit patch, which one is working. FixAudio.zip

Can you confirm RealtekRTL8111 is loaded ? Post IOReg file with IORegistryExplorer.app v2.1

Give this a try Inspiron 5559 OC0.6.8.zip

With the OOB bcm94360ng, make sure you disable / remove all patches and kexts related..ie BRCM* and Airport* If touchpad stops working, try disabling SMCDellSensors.kext

You could try this guide https://www.insanelymac.com/forum/topic/343172-guide-lenovo-thinkpad-p50-with-opencore/

Strange, you are part of a few that has issue with Brightness control on boot. I don't have this issue on my E7270. As for the Wifi, try turning it off and on or switch it to itlwm.kext + heliport.app (can't say it's better since I don't use it). If possible, replace with a more supported device..DW1830, DW1560, or DW1820A.

For Intel Wfi / BT, just replace config.plist with the attached and add the 3 kexts to the Kexts folder E7270_IntelWifi:BT.zip

Use files from here, but you'll need to make some edits for the Intel Wifi in the Config and add Intel kexts

Weird that you have to upgrade again, the bootpack I attached are all OC 0.6.8 files The buttons issue is due to the lack of support of VoodooI2C..

Did you make any changes to the USBPorts kext? Are all the USB ports tested and working? Does it have USB-C port? is it working? hot plug? HDMI port / DP port working? With audio? USB-C with adapter -> display working? Correct Fn keys work for Brightness? You don't need the Bootstrap folder. It's been removed since OC 0.6.6

@GotierLdl Can you post new IOReg file? Just want to see what's else is needed As for the CPU, that's just cosmetics.

Give this bootpack a try Pick the Config for your system depending on wireless device (Intel or Broadcom) Latitude_5590_OC_0.6.8.zip
