Hackbgrt-1.5.1 offers the safest balance: it doesn’t flash your BIOS, works across all major OSes, and respects your display’s native resolution. Hackbgrt-1.5.1
The most common user base. macOS is particularly sensitive to BGRT quality. A pixelated Apple logo during boot ruins the "real Mac" illusion. Hackbgrt-1.5.1 lets Hackintosh users display a perfect, retina-quality Apple logo. | Tool | Approach | OS Support |
BGRT is a UEFI feature (introduced with ACPI 5.0) that stores a bitmap of the boot logo in memory. During early boot, the kernel or bootloader can display this logo, creating a seamless transition from firmware to OS. Hackbgrt avoids all of these by targeting the
The problem? Many UEFI implementations lock this table, and even when they don’t, changing the logo typically requires:
Hackbgrt avoids all of these by targeting the Linux kernel’s runtime memory after the BGRT has been loaded.
Hackbgrt-1.5.1 replaces the default, low-resolution logo data in the BGRT with a high-resolution image of your choice. Instead of a pixelated brand logo, you can boot into a crisp, custom image that fills the screen correctly at native display resolution (e.g., 1920x1080 or 3840x2160).
