"DOS" like screen when Leopard starts?

[patthai]

Hello all,

I'm kind of new to Macs and all. I recently re-installed Leopard 10.5.5 and made the upgrade to 10.5.6 Everything works perfectly fine. The only thing is that when sarting up and also when shutting down, I get instead of the Apple logo and the little spinning wheel thingy, a black startup screen that looks like DOS.

The Mac starts fine, it's just the interface/screen that is not normal. My local mac shop told me to type into Terminal the following code but to no avail: nvram boot-args="" The command is not recognized.

They then advised me to reinstall Leopard again but as I have customized the mac already I wish to keep everything as it is and solve this problem without reinstalling. Does anyone have any ideas?

Thanks!

You can turn this off - it is turned on to help diagnose any hardware problems.

I've had a look around and I really can't find anything that details on it - there was a post here once upon a time that detailed it but I can't find it.

Duff-Man says....sounds like you are starting up in "verbose" mode. For those not used to fooling around with the terminal you should be able to toggle this on/off with any one of several utilities - many of them free too....try Onyx..it's handy to have around anyway....oh yeah!

Did you try it w/o the quotes? They gave you the right command. What happens if you type nvram and hit enter?

Re-installing the OS won't fix that one btw as the arguments for nvram are stored in nvram.

Zapping the PRAM will get your pretty spinning gear back.

Make sure you don't release the keys until you hear the 2nd chime.

Thanks for all your help but unfortunately none of the options did the trick. I downloaded Onyx but cannot find where to be able to disable/enable this option. Any more suggestions?

Thanks!!

Load up Terminal, then paste the following code in and hit enter.

sudo nvram boot-args=

Load up Terminal, then paste the following code in and hit enter.

sudo nvram boot-args=

would this also toggle it to turn on the diag mode?

No, to turn it on, use this code:

sudo nvram boot-args="-v"

No, to turn it on, use this code:

sudo nvram boot-args="-v"

thank you

This didn't work out either... The code worked as in it came back to me asking for my password. After I typed that it went back to the 'prompt' and the screen still appears when shutting down and starting up.

I also downloaded MacPilot which has a startup customization screen but I don't know if the answer is in there. Attached a print screen of the tab.

Hmm, it appears that the problem's not in nvram then. Try typing this:

cp /Library/Preferences/SystemConfiguration/com.apple.Boot.plist ~/Desktop/boot.txt

That should put a file called boot.txt on your desktop. Attach it to a post here so that we can take a look at it.

Attached. Thx again for all the help! Much appreciated.

Unfortunately, that all looks right.

Hi all,

Does this mean that there's nothing I can do about it?? Hmm... Let's see what the new year brings

I wish you all a very happy New Year 2009!
