    My friend has a macbook g4 that starts up with rolling text(black screen). She wants it to start up and go straight to the apple logo screen. My mac pro starts up that way(apple logo), but because I am new to mac I am not sure how to make that change. Can anyone help?

    powerbook G4. :)

    Anyways, sounds like its in a verbose boot, I think you can change that in Xpostfacto.

    Has it ever started up correctly? Cause when the computer boots to the black screen something is pretty wrong. Ultimately the best way to troubleshoot this is to startup using the System DVD's (or CD's) and run Disk Utility.

    Most likely you're gonna have to reinstall OS X to get the computer running correctly again. And as for Mac bootup screens they should always boot to the Apple logo.

    And is this a G4 (old Mac)? Or a MacBook (new Mac)?

    Please forgive me, but I am unsure as to what you mean by that. I come from a DOS world and am not familure with UNIX yet (i just made the switch to mac about 3 months ago). Could you please elaborate on that a bit?

    verbose boot? xpostfacto?

    To be honest, I am not sure. The G4 is not mine, but I do know that once it gets past the black screen with rolling text it works just fine.

    Thanks for the help Daedalus256. Your keyword (verbose boot) allowed me to find the answer I was looking for. Below is what I found on another forum.

    Open up Terminal

    1. Enter: sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
    2. Enter password
    3. Make sure the Quiet Boot key is set to "yes." If its not there, add it.
    <key>Quiet Boot</key>

    4. Delete "-v" from the Kernel Flags key if it's there.
    5. Ctrl+O to save, Ctrl+X to exit

    nowhere fast
    What you found should work, or you can use a terminal command i show below.

    Verbose boot means exactly what it implies; everything the computer's doing during boot is shown in words on the screen. it's always been an option on most any operating system, windows can do it (at least in XP it was an option), linux sometimes does it by default.

    On a Mac, you can hold down cmd-v during startup to display all that text, or you can use a terminal command to set it to verbose boot every time. Apparently at some point your friend's computer was owned by a nerd who liked seeing the startup sequence (I use cmd-v sometimes just for kicks, but it's so fast on new macs that the grey apple is usually nicer).

    Anyway you could also open terminal and enter:

    sudo nvram boot-args=""

    it will probably ask you for password, then you're set.

    I wasn't so sure if this command would work, but I was backed up here:
