apple_set_os loader

Tiny EFI program for unlocking the Intel IGD on the MacBook for Linux and Windows. This loader will load bootx64_original.efi once apple_set_os is loaded and fix the issue which apple_set_os cannot be loaded sometimes.

Based on 0xbb's apple_set_os.efi https://github.com/0xbb/apple_set_os.efi

Usage

1. Set Security Boot to "No Security"

2. Mount EFI partition

3. Rename /EFI/Boot/bootx64.efi to /EFI/Boot/bootx64_original.efi

4. Copy bootx64.efi from this repository to /EFI/Boot

5. If you dont have Windows installed, you need to bless the efi so the efi will run at startup.

Update:
When you start up using the option command to select the OS drive, you'll be presented a 5 second countdown where you can turn on/plug in your egpu before it proceeds.
If it's already on, you'll see your device...possibly not existing.  If there's any issues, it will revert to bootx64_original.efi and you'll have a mix driver set which causes some odd issues.

I'm using an external display and if you do the same, you could just disconnect the display from a direct connection to the apple device...this will elimiate the need for this loader.

This is built via mac. Windows should work but using cmd or powershell instead. This requires docker to be installed and running

1. Download the files and expand to a folder
2. CD to the folder in terminal in MacOS

Build via docker (output file will be located in the same folder)

docker build --no-cache -t apple_set_os_loader .
docker run --rm -it -v "$(pwd):/build" apple_set_os_loader
rm -f bootx64.efi bootx64.so
docker run --rm -it -v "$(pwd):/build" -w /build apple_set_os_loader make -B V=1
