Since I did not currently have Mac OS X running on the old MacBook, installation was simple. Related: See which upgrades are compatible with your MacBook with My Upgrades Tool Sure, I could keep it on a previous release of Mac OS X, but where’s the fun in that? So what I’ve done is tried to install five different versions of Linux on the MacBook - Ubuntu 16.04.2 “Xenial Xerus”, Linux Mint 18.1 “Serena” with the Cinnamon UI, Antergos 17.4, KDE Neon, and Fedora 25 Workstation. I’ll talk about the installation process for each and about how they operated - or not - on a Intel Core Duo 2 2.4 GHz MacBook. Why would I want to do this? This MacBook is about nine years old and frankly, it just doesn’t have the ability to run newer versions of macOS. One of the more common themes in the comments was “Why run Linux in a virtual machine? Why not just install it as the only operating system on a Mac?” This week, I’m grabbed the old 13-inch white 2008 MacBook that I converted to a Chromebook last year and installed various Linux distributions on it just to see how well it operates. (Although in this case, the boot manager will operate silently.) Installing a rEFInd as a third boot manager is not necessary.A few weeks ago we ran an article about how to install Linux on a Mac, and it generated a lot of comments. Ubuntu will by default install Grub, which is also a boot loader and boot manager.

The firmware on the Mac logic board contains a boot loader and boot manager.

You can install the rEFInd boot manager if you wish, but consider this. If this is the case with your Mac, then you will need to install to an USB drive. Some releases of Ubuntu can not be installed on the internal drive of newer Intel Macs. If your Mac has the T2 chip, then you have to remove Secure Boot and allow External Boot. I also assume here your Mac does not have the T2 chip. If not, then you should update your question. I assume here your MacBook Pro is a newer model that would capable of 64 bit EFI booting Ubuntu and have at least 4 GB of memory.

After doing so, the Mac should boot Ubuntu by default. While the Mac should automatically boot Ubuntu, you can also select to always boot from Ubuntu by holding down the option key at startup, then selecting the icon label EFI Boot. The Grub boot files installed by Ubuntu are compatible with the Mac Startup Manager.
