From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've run Ubuntu on a Macbook Air 2012 and also on a Macbook Pro 2015 for about 5 years. Both have worked really well. I found early on that using Xorg made things seem faster (but that may be subjective). I've read that Debian (netinst) is meant to be really good on older macs and it's something I'll try at some point.
