FMEO.TV – Build an OS X / macOS (up to 12.0!) Boot Disk

FMEO.TV Episode #023

UPDATED to include up to macOS Monterey!

In this episode of FMEO.TV, Mike shows how to build Mavericks USB boot media using OS X’s built-in createinstallmedia command.

Yosemite, El Capitan, Sierra, High Sierra, Mojave, Catalina, Big Sur & Monterey UPDATE: Great news! This command works just as well for versions of OS X and macOS up through Monterey! Simply substitute the correct file name in the Terminal command below and away you go!

Note the slight change with 10.13 – 10.15, 11.0 & 12.0. The –applicationpath switch has been deprecated (no longer needed).
