Dell E7250 Hackintosh

This repo contains all the fixes for E7250 on macOS Monterey.

The EFI folder can also be used on older versions of macOS. However, the main support of this branch is based on Monterey. If you want an EFI made specifically for Big Sur, check the 11.0 branch.

Tested on:

What works?

Everything...

Download and Install

Go to the Releases page of this repo and download the latest release. Then, copy the EFI folder to your EFI partition... That's it.

Graphical glitches in macOS

There are three ways to fix the horizontal glitches (as seen here) in macOS.

1. (Recommended) Enable 'Enable Legacy Option ROMs' in the BIOS by clicking General>Advanced Boot Options. Here is a picture of that option.

2. If you want to use pure UEFI as a workaround, you can use one-key-hidpi. Download and run the code and select 'Enable HIDPI (with EDID)'. Then restart your computer and the glitches should be resolved.

3. Patching Display EDID [WIP]

First we need to download these three Applications: Hackintool, AWEDIDEditor and HexFiend

• Open Hackintool and go to the Displays tab and click the Export icon/button on the bottom-right side.
• On desktop, you will see some new files appeared, now open the EDID-***-****-orig.bin file with AWEDIDEditor
• Go to Detailed Data tab and change H. Sync Width: value to 100.
• Save the EDID as Patched-EDID or whatever name you like just to know which one is the patched one
• Open the Patched-EDID with HexFiend and make sure you expand it so it contains 8 columns of code bytes and copy the 128 bytes of it.
• Add child AAPL00,override-no-connect to EFI>OC>Config.plist>DeviceProperties>PciRoot(0x0)/Pci(0x2,0x0) with Data as the type and paste the 128 bytes of code in there
• Save the config.plist file and reboot, Enjoy pure UEFI without a garbled screen.

Intel WiFi

Starting with v2.3, AirportItlwm is included in the EFI but disabled to ensure stability. To enable Intel WiFi, enable it in the config. The EFI will only have stable versions of AirportItlwm. So if you want to experiment with Intel WiFi, you can do so by visiting the itlwm repo and downloading the latest alpha build. Stability can be much worse, so use with caution! Also, do not forget to enable IntelBluetoothFirmware and BlueToolFixup in the config to enable Bluetooth on Monterey!

If you experience no internet with AirportItlwm, I suggest switching to itlwm and see if it works there.

Since Monterey, the Bluetooth implementation has changed and therefore causes issues such as: Bluetooth will be broken after sleep. As a workaround, typing the following command in Terminal may fix this issue: sudo killall -9 bluetoothd BlueTool

If you want Continuity features: Buy a Broadcom card on eBay or your trusted website. You can check the Dortania buyers guide to see which card is the better option: Link

Touchscreen

For touchscreen models, I also added VoodooI2C to take advantage of the touchscreen display. However, it is disabled. If you want to use it, you have to activate all VoodooI2C-related kexts in the config! Since v3.0 there is a new touchpad kext that also uses VoodooInput. So you need to disable VoodooInput that comes with VoodooPS2 and enable VoodooInput that comes with VoodooI2C, otherwise the system will not boot.

How to Install macOS Monterey

There are two ways you can install Monterey:

1. If you have an already working macOS, download the Installer from the App Store and make a bootable Installer with createinstallmedia by using this command in Terminal: sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

2. If you are using Windows, use macrecovery.py from the offical OpenCore release package. Follow this guide to understand how it works.

After you have created a bootable Installer, copy the EFI folder to the EFI partition and install as usual. After the installation, mount the EFI partition of the installed OS and copy the EFI folder to its partition.
