Real boot loaders have embedded Forth interpreters!

  Do Macs still have this?

    No, it stopped for the Intel switch, I believe.

      Yeah, the Open Firmware preboot Forth console was a PowerPC only thing. Now Apple’s bootloader is actually a tiny macOS. As much as I don’t like the complexity this brings, I do strongly approve of a boot environment that supports proper input devices and video. My iMac Pro’s (intel, non-macOS-based bootloader) bootloader drops keyboard inputs when typing my long passphrase because I type too fast for it. The Mx macs no longer have this problem.

        And the nearly indestructible protection that DFU brings.
