The EFI folder can also be used on older versions of macOS. However, the main support of this branch is based on Sonoma. If you want an EFI made specifically for Monterey, check the [12.0 branch](https://github.com/SkyrilHD/Dell-E7250-Hackintosh/tree/12.0). For Ventura, check the [13.0 branch](https://github.com/SkyrilHD/Dell-E7250-Hackintosh/tree/13.0).

With Apple dropping support for all pre-Kaby Lake machines on Ventura and newer, graphics support for Broadwell and other previously supported GPUs has been removed as well. To restore GPU acceleration, we have to both weaken SIP and modify the root volume. Modifying the root volume results in losing the ability to apply Delta OTA updates. The root patches must be re-applied after each macOS update. To add the required kexts back to the system, use a tool called OpenCore Legacy Patcher, which has an amazing team that adds back support for older Macs.

- Go to the latest OpenCore Legacy Patcher Release page: [Link](https://github.com/dortania/OpenCore-Legacy-Patcher/releases)
- Download 'OpenCore-Patcher-GUI.app.zip'
- After download, open the app and select 'Post Install Root Patch'.
- Download 'OpenCore-Patcher.pkg'

- Wait for a while and reboot the system after it finishes.

## OTA from Monterey to Sonoma
## OTA from Monterey to Sequoia

Since v5.0 installing Sonoma via OTA should be very easy. Replace your Monterey EFI with Sonoma and boot as usual. Open 'System Preferences' and go to 'Software Update'. Download macOS Sonoma and proceed with the installation as a normal update. After update, run OpenCore Legacy Patcher to fix GPU acceleration. Here's a little [guide](#GPU-acceleration-on-Ventura-and-newer) you can follow. Keep in mind that replacing Monterey EFI with Sonoma drops AirportItlwm support on Monterey! If you want to upgrade to Sonoma over WiFi, replace the Sonoma version of AirportItlwm with a Monterey version. After the update, you need to roll back the currently version of AirportItlwm to add WiFi support on Sonoma. The same applies to Ventura.

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.
