Why wouldn’t these work for the PPC systems?

I am pretty sure these do work on PPC systems too, although I no longer have one around to test it out. I know the zapping NVRAM is the same - but it used to be called PRAM? What’s up with that?

You can use all of those commands except pushing D to start up the hardware test from the system disk.. Other than that they work

Does anyone know when exactly you are suppoed to hit these buttons at startup? Maybe I am doing it too late but I am only seeing a smiley logo and login?

You need to do it as soon as the machine starts, and you hear the chord. If you reach the login screen, you’ve waited too long…

These may all work on Intel systems, but they also work on every OSX Mac. I love a list though, and Eleven is my lucky number, so ..like..YEAH!

Well I just brought a second hand imac, and it has Leopard installed on it. I want to put my copy of tiger on it, but pressing c doesnt work.
Did you know that Leopard is like a virus? Once its on your computer, you can never get it off? Thats my situation. Its a shame Apple has always had absolutely shocking support for removal of things.(Can you uninstall apple applications as easy as you can on windows?-Hell no)

If anyone has any idea how I can format a leopard install and put on tiger I’d appreciate that. Thanks
AC

Mr Aaron cross you could simply open the terminal run the command “sudo rm -rf /” and enter your password and press enter. then boot the cd,

I was trying to use the boot commands on an imac running tiger. I had a leopard upgrade boot cd in the drive, and for 3 hours I was unable to get the computer to recognize any boot options whatsoever — it would just boot to the regular login screen no matter what.

I even tried to use the “menu” button on the apple remote as the computer was booting (as was suggested on another website) — no dice.

I finally tried pulling off the western digital external hard drive off another usb port (the only other equipment plugged into the mac) and the next time I tried to boot with the “c” key it booted right into the upgrade disk.

So it appears that having an external hard drive in another usb port can hose the boot options, FYI. I wasn’t getting anything that even looked like the boot option keys were being recognized, but it worked as soon as I removed the external hard drive.
