The EFI (Extensible Firmware Interface) folder is a set of “drivers” and “instructions” used by a computer to boot an OS. Our EFI-Library contains system-specific files and settings needed to start up the system properly. It’s basically drivers that help your hardware and the OS communicate with each other effectively.

To avoid your Apple account and/or services from being suspended, during your initial installation of a macOS on the computer, you MUST generate your own unique SMBIOS. This is a set of identifiers that help ensure compatibility and allows you to use various OS features. They have to be unique for each device. 

If the EFI folder is not working for you, it could be due to incompatible hardware, hardware mismatch, software conflicts, issues with the bootloader, or firmware limitations. To troubleshoot the problem, make sure the EFI folder is set up correctly for your hardware, check for conflicting software, and update your firmware. Don’t forget that you can always mix and match different EFI files to get the perfect set of files for your specific computer.

If certain features like WiFi or Bluetooth are not working after booting your system, it could be due to incorrect drivers, incompatible hardware, incorrect BIOS settings, or configuration errors. You may need to install the correct KEXTs, check hardware compatibility, adjust settings, or fix installation errors. It’s important to note that achieving full functionality can be challenging if your hardware doesn’t match the one mentioned in the folder.

It’s best to use an EFI folder specifically tailored to your own system’s hardware configuration. Using an EFI folder from a different system with slightly different specs may cause compatibility issues or not work correctly. It’s recommended to customize the EFI folder to match your hardware to ensure optimal performance and compatibility. You are always free to mix and match our EFI’s to meet your hardware needs.

Our technician can create a custom EFI folder and help you with every aspect of the installation process. We also provide warranty support to ensure the system keeps performing well after security updates, adding hardware and other changes you may want to make to your build.
