A question and answers on the differences between BIOS and EFI booting on - This provides the basics of the preceding, but is more concise.

Adam Williamson's blog entry on how EFI works - This page describes the theory behind EFI-mode booting.

I recommend learning more about EFI booting before you start, though, so that you don't make some basic mistake like booting the installer in BIOS mode or setting up your partitions in the wrong way. You could try it, though, and then fix any problems you encounter after the fact. In practice, I'm not sure that will work - Apple does everything a little differently, and so few enough people do it this way that I can't promise it would work. In theory, if you install Ubuntu in EFI mode, it should install GRUB 2 in a way that will make it the default boot manager, and it should provide options for booting both Ubuntu and OS X. You could rely on GRUB 2's boot manager features, or you could install another tool, like gummiboot/systemd-boot. If you simply dislike rEFInd, you can certainly do without it. Given that most of these tools are more convenient to use than is Apple's built-in boot manager, most users leave them set in the boot order such that they're called before the OS X boot manager. You'd still need something (GRUB, rEFInd, or some other boot loader or boot manager) to launch a Linux kernel, though. You could rely on Apple's boot manager to control which OS to boot, and in that case no non-Apple tool would be involved when booting OS X. If you're dual-booting Ubuntu and OS X (or macOS, as it's been recently re-named) on a Mac, it's a practical necessity to add something to the boot process. Also, some boot loaders, such as the GRUB 2 boot loader that's popular with Linux distributions, function as boot managers as well as being boot loaders. Neither rEFIt nor rEFInd is technically a boot loader, although the Linux kernel creates a blurred line, because it includes a feature (the EFI stub loader) that enables it to function as its own EFI boot loader. A boot loader does not need to interact with the user directly (although it could). I was more motivated by boot issues on UEFI-based PCs, but rEFInd remains a way around the limitations of Apple's boot manager.ДЄ boot loader, by contrast, loads a kernel into memory and transfers control to it. I forked rEFIt into rEFInd after rEFIt fell into disrepair. I presume this is what motivated Christoph Pfisterer to create rEFIt. The Mac's built-in boot manager is awkward to access and limited in its capabilities. On a Mac, you launch the built-in boot manager by holding down the Option (or Alt) key as the computer starts up (when the startup chime sounds). Most EFIs, including Apple's, include their own boot managers however, these built-in boot managers are usually very primitive. A boot manager presents a menu or some other user interface tool to enable you to select which OS to boot.

Note: Starting with Ubuntu 18, the installer software should automatically create the files necessary to boot Ubuntu on a Mac.

The process of making the Ubuntu appear on the Startup Manager is a fairly trivial.

Normally, this is the first partition on a Mac computer. Ubuntu installs grub and other files in the first EFI System partition on a Mac computer.
