Clover EFI Bootloader is a boot manager for systems based on UEFI firmware and legacy BIOS, widely used in unofficial macOS-compatible computers (Hackintosh), as well as allowing the booting of other operating systems such as Windows and Linux distributions.
It works by loading the operating system from the EFI partition, offering support for ACPI, kext injection, SMBIOS adjustments, boot-time patches, and detailed configuration of boot parameters. Through these functions, you can adapt the boot process to the specific characteristics of the hardware, ensuring greater compatibility with macOS.
Clover EFI Bootloader allows you to select installed systems, set boot arguments, enable or disable devices, apply fixes to ACPI tables, and control resources such as graphics, audio, and power management directly at boot time. It also supports graphical themes, making it easier to visually identify available systems.
The project is based on open-source code and is often updated to keep up with changes in macOS and UEFI standards, being widely used by enthusiasts and technicians who perform custom installations of Apple's system on compatible hardware.
