When you're setting up a Hackintosh, the single most important tool in your process will be the bootloader, which is the program that enables your computer to "boot" Mac OS X. Ever since the release of OS X El Capitan in 2015, the new Clover Bootloader has rapidly become the most popular bootloader within the Hackintoshing community, and for good reason: compared to the old Chameleon/Chimera bootloaders, Clover offers faster boot times, more features, and better hardware compatibility. However, Clover can also be a bit tricky to work with, due to its use of a feature called the "EFI partition" (also known as an EFI system partition, or ESP). Just what is the EFI Partition, and how do you use it? That's what this guide is here for.
