I just got my beautiful 23" cinema display, now i am trying to have it as my main and only screen so i can close the macbook pro. (Of course i have external mouse and keyboard.) I know it is possible, i read a tutorial about it last year, just cant find it no more. Anyone knows how to do it? Thanks!
 
dont install any third party app, it's not necessary

Just make sure the macbook is plugged to the wall as it can't run in clamshell on battery.

boot the macbook completely into the OS,make sure your monitor is on and connected to the macbook, then close the macbook lid, then press any key on your external keyboard or mouse, voila... the external display will show your desktop.
 
I think you're mistaken... It can definitely run on battery in clamshell. Just make sure it can wake from bluetooth or usb, and it'll wake up.

That's not what :apple: says: http://support.apple.com/kb/HT3131?viewlocale=en_US
If you are using a wired keyboard and mouse:

1. Make sure the computer is plugged in to an outlet using the AC power adapter.

If you are using a Bluetooth keyboard and mouse on a Bluetooth enabled Apple portable:

1. Make sure the computer is plugged in to an outlet using the AC power adapter.
 
I'm definitely using my apple wireless keyboard and mouse in clamshell without my AC adapter

Hmm despite what :apple: says in the link I gave above, you are absolutely correct as this guy also notes in an earlier thread (and I was able to replicate just now):

At first the macbook would only work with the external display when the charger was plugged in but then i discovered that if you open the lid AFTER you are in clamshell mode, you can unplug the charger and the LCD will remain off and the external display works.

Thanks, learned something new :)
