I need a confirmation if the EFI is working on other models, so I can complete my list. Thanks!
I noticed that my E7250 has nearly the same specs as other Exx50 models, so this repo was created. This will NOT replace the E7250 repo.
Tested on:
| Model | Latitude E7250 |
|---|---|
| CPU | Intel Core i5-5300U |
| GPU | Intel HD Graphics 5500 |
| RAM | 16GB DDR3 1600Mhz |
| Storage | SK hynix SC210 mSATA 128GB |
| WiFi | Intel Dual Band Wireless-AC 7265 |
| GSM/LTE | Sierra Wireless AirPrime EM7305 (DW5809e) |
| Software | macOS 12.3 Monterey |
| Exx50 model | Supported? | Additional notes |
|---|---|---|
| 13 7350 | Yes | 2 |
| 3550 2015 | Yes | 3 |
| E7450 | Yes | -/- |
| E7250 | Yes | -/- |
| E5550 | Yes | 1 |
| E5450 | Yes | -/- |
| E5250 | Yes | -/- |
| E3450 | Yes | -/- |
Bold: confirmed working
Italic: not confirmed
1: disable your dGPU (if you have one) with a SSDT
2: MacBook8,1 is not supported anymore, so use SMBIOS that comes with this EFI
3: Follow this for full functionallity
Disclaimer: The list was created based on the specs. Please correct my mistakes
Everything...
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.
- Works really good
- no Verbose (Apple Logo)
- little glitches at boot (Graphics Driver loads)
- brightness control now works via F11/F12
- Apple's audio driver as main
- sleep works
- Bluetooth works and can be disabled
There are two ways to fix the horizontal glitches (as seen here) in macOS.
-
(Recommended) Enable 'Enable Legacy Option ROMs' in the BIOS by clicking General>Advanced Boot Options. Here is a picture of that option.
-
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.
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.
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
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 v2.0 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.
If you experience a USB port not working or you have issues with it, the result would be since this EFI uses a USBMap of E7250. You need to map your USB by following this issue. It would be very helpful to post a USBMap as pull request or on the issue page, so I can add it to the project.

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

All this was written on an E7250 with Monterey installed :D
