OpenCore for Dell Latitude e7240 updated for Big Sur with Azurewave AW-CE123H WiFi support

BigSur fork notes

UPDATED POST-INSTALLATION TO OPENCORE 0.6.4

I am just a tech enthusiast and explorer. I do not take responsibility for any damage made to your laptop.

Specs:

Intel i5-4310U (4) @ 2.00GHz
Intel HD Graphics 4400 (integrated GPU)
1366x768 display (LED paper, non-touch)
12GB DDR3 RAM
ALPs trackpad (built-in laptop)
Azurewave AW-CE123H (equivalent to dw1550)

Note: My original WiFi card was dw1601, which was not supported. If you have another WLAN card and no knowledge about Hackintosh-ing, don't update unless you are ready to use only LAN connection. See list of supported WiFi cards.

If you have Mojave and want to update to Big Sur first update your system to Catalina and then proceed

Before updating any kext, create a pendrive copy of the actual EFI so if something doesn't work, you can restore it. Backups always help.

What works

Built-in keyboard (backlit, with volume keys)
Built-in trackpad (multi gestures) - upto 4 finger gestures supported
HDMI video/audio with hotplug
Native WiFi (2.5GHz and 5GHz) via Azurewave AW-CE123H
Bluetooth (with AirDrop and Handoff) using Azurewave AW-CE123H
Native USB3.0 and USB2.0
Native audio with AppleHDA
Built-in mic
Built-in camera
Native power management
Battery status
Display backlight controls with smooth transitions, save/restore across restart
NVRAM
Integrated Graphics
Wired Ethernet
Harddrive, Battery, WiFi status lights
SD Card Reader

Note: The above is what I've tested. There may be things you're looking for which might not be listed. In that case, drop an Issue and get me to test it for you.

What doesn't work

WiFi manual on/off switch which is on the side of the laptop. It only works for the Bluetooth module but NOT WiFi. I found this an odd issue but I'm okay with it. Note: This could be because of my selection of WiFi card. The original had three pins, but this one has two. Good luck with yours.

Ending Note

Below you have info about installation from forked repo

OpenCore - post-installation: 0.6.1

What you need:

Lenovo Y50-70 (or Y70 Haswell) with either 1080p or UHD/4K display
macOS or OS X downloaded from the Mac App Store
8GB USB stick with EFI folder pre-installation on EFI Partition and MacOSX installation.
Broadcom BCM94352Z for native WiFi (Lenovo FRU: 04X6020, Lenovo PN: 20-200480) or MacOS Broadcom compatible model with BIOS unlock.

What works:

Expect to work:

built-in keyboard (with brightness keys)
built-in trackpad (multi gestures)
HDMI video/audio with hotplug
AirPlay mirroring to AppleTV
native WiFi via BCM94352Z
Bluetooth (with handoff) using BCM94352Z
native USB3
native audio with AppleHDA
built-in mic
built-in camera
native power management
battery status
backlight controls with smooth transitions, save/restore across restart
accelerated graphics for HD4600 including OpenCL
wired Ethernet
retina scaling (in the case of UHD screen)

Not working:

Nvidia GTX 860M 4GB (It doesn't work and it will never work)
card reader

BIOS settings:

To start, set BIOS to Windows 8 defaults.

Then insure:

UEFI boot is enabled
secure boot is disabled
enable Legacy Boot (but UEFI first) and you may experience less boot time glitches

For the UHD model, the DVMT-prealloc BIOS setting must be changed to 128MB. One of two methods can be used:

use a EFI shell to change the DVMT-prealloc from the shell.
use a patched BIOS which unlocks the advanced menu

What you have to do:

Install MacOS with pre-installation EFI
copy EFI post-installation folder on EFI partition of your HD.
Modify SMBIOS data with your information for imessage/facetime

(You have to import from your older configuration or generate a new one)

- Use MacSerial to generate your SMBIOS --[Macserial](https://github.com/acidanthera/OpenCorePkg/tree/master/Utilities/macserial)
- MacSerial Example in terminal macserial -a | grep -i iMac19,1
