Enterprise
Tool intended to help the process of booting Linux on Intel Macs.
Enterprise is a custom UEFI bootloader designed to load Linux distributions directly from ISO files on Apple Mac computers (even those without UEFI booting support). It is designed to compliment Mac Linux USB Loader, though it can also be used separately (albeit with some setup work). The purpose of Enterprise is as the first stage in a two-stage booting process for Mac Linux USB Loader-created USB drives. Essentially, Enterprise loads GRUB, giving it configuration settings and the location of necessary files inside of the desired ISO, and then the distribution is booted.
Enterprise will soon support booting multiple distributions, so you can have more than one distribution per USB stick. This way, you can test out multiple distributions.
