These instructions work for me on the Big Sur developer beta, which doesn't really fit the second line: "It should work on all OS X versions before Mavericks (OS X 10.9). It does not work on OS X 10.10 (Yosemite), 10.11 (El Capitan), or 10.12 (Sierra)."

Is this old info?

Its incredibly old, probably written years ago. If you managed to make the guide work, cool --jacob1 13:56, 21 September 2020 (UTC)
