Clover Bootloader vs Visor Boot Manager

Clover Bootloader starts macOS, Windows and Linux systems on Macs and PCs with UEFI or BIOS firmware. It can launch through UEFI directly or use CloverEFI to emulate UEFI, and supports UEFI and legacy boot modes. Its graphical interface can be customized with themes, icons, fonts, backgrounds, animations and mouse pointers. Users can create boot entries for other operating systems, while the interface can save preboot logs, screenshots and OEM ACPI tables for diagnostics. Settings are held in an XML config.plist file in EFI/CLOVER. When firmware Secure Boot is enabled, Clover’s Secure setting limits booting to signed binaries. The repository links to a separate theme manager and theme collection, and its README points users to AppleLife, InsanelyMac and macos86.it forums. Build procedures are provided for macOS and Ubuntu 19.10. Clover incorporates OpenCorePkg libraries for kext injection and patching. It is free under the BSD 2-Clause License, which permits source and binary redistribution. The releases page lists version 5175 as latest, with six assets.

Visor Boot Manager is a graphical UEFI boot manager for Linux and Windows EFI programs. It can start Linux EFI-stub kernels and Unified Kernel Images, or chainload other EFI executables, including Windows. With no configuration, it detects Windows, kernels, UKIs, and BLS or OSTree deployments, and can derive a root command line automatically. Its menu supports themes, icons, animations, wallpaper accent colors, mouse and touch input, and live USB hotplug. For alternate boot states, it supports Btrfs, Snapper, Timeshift, and plain snapshots, along with OSTree deployment browsing and automatic rollback. Visor also supports encrypted boot artifacts and a single-password LUKS handoff. Secure Boot verification works through shim, and the installer supports sbctl signing. The bootloader is one approximately 340 KB EFI binary, without external dependencies or a scripting language. It builds for x86_64 and AArch64 and can be built from source or installed from the Arch User Repository. It uses the BSD 2-Clause license and is free at free. Visor requires UEFI hardware and does not support legacy BIOS.
