I think its because its a fake mac or file is deleted i guess
Photo Booth is owned by the system and you are not able to delete it. If you had it in the Dock but removed the icon from the Dock you can still find it in the Applications folder.
If you have Mac OS 10.5 (Leopard) Photo Booth can be found in the Applications folder.
PhotoBooth can be installed from the Mac OS X (Leopard) installation discs.
You can't. You have to install it on your computer if you want it. If your friend wants photo booth then they have to install it on their Mac computer.
on the photo booth you can take pictures or videos of yourself with a bunch of different effects!
naaa
Try entering the installation CD. If you are lucky, you could copy the program to the applications folder. Did you already look for 3rd party apps that can do the same or better than Photo Booth? In case all of the above does not work out, reinstall Mac OSX and Photo booth will be restored. (Btw, it is recommended to reinstall OSX every now and then anyway so do not hesitate.)
well you nee mac osx lion so the new photo booth come with the update
if you mute the sound of your computer.
Only if he borrows somebody's Mac.
If you are recording a video in Photo Booth the internal Mic will pick up any sounds that come from other applications.
