Yes in OS boot loaders. FreeBSD uses it, and I think Apple uses it for OSX. Possibly iOS.

  Sorry, I'm wrong regarding OSX and iOS. OpenFirmware is used at numerous places, but Apple is not one of them.

    Apple used it when they were still PowerPC-based. They sadly dropped it with the move to Intel.

      You used to be able to boot up with Command+O+F and get a Forth prompt. (Although I have a hazy recollection that on some models they didn't include a screen terminal, so you couldn't interact with it...)

    Apple used to use it in the PowerPC days as did Sun - https://en.wikipedia.org/wiki/Open_Firmware https://en.wikipedia.org/wiki/Open_Firmware http://www.brendangregg.com/Sun/obp.html http://www.brendangregg.com/Sun/obp.html
