Open Source Swift Boot Software

macUSB is a macOS utility that streamlines the creation of bootable USB installers for macOS and legacy OS X versions, taking the complexity out of preparing installation media on modern Apple Silicon or Intel Macs. It automates disk formatting, installer detection, and content writing so that you can revive or install operating systems on older hardware—something that has become more difficult since Apple’s transition to its own silicon. With support for handling various disk image formats and applying necessary fixes for installers with older certificates, macUSB demystifies what was once a command-line-intensive process. Its goal is to make preparing bootable media accessible to users of all skill levels by intelligently managing installer images and systems, giving Mac users a straightforward path to restore or reinstall macOS across generations.

MBR2 is a remote control for various Boot Loaders such as GRUB, Limine, etc. It is a series of programs that run on various Operating Systems such as Linux, BSD, MacOS, Windows, etc. These programs all do the same thing from WITHIN THAT OS: They set the values of GRUB, Limine, etc. then restart the computer effectively allowing you to restart in a different OS without waiting for GRUB, etc. to load and make your choice. No more 'missed' choice selection when you get distracted waiting for the computer to shut down then reboot into the Boot Loader! We all know the frustration of turning our head back to the screen and seeing the wait timer has expired and booted the default AND WRONG operating system! LOL! You must download the correct version for each OS you use and install it in that OS. Win for Windows, Lin for Linux, BSD for BSD, etc. All images provided by Bridgett Marlow and released under CC0.
