PowerPC Macs (in the 2000s, before the switch to Intel) did indeed require a manual step to update Boot ROM/firmware - a different mechanism than resetting the PRAM. You'd run the installer, then either shut down or reboot the Mac. As it booted, you'd either hold down the power button or the interrupt button (depending on the model) to initiate the update. |
