For those of the few people on this forum that own a Mac: surprisingly, those are customizable too! Just a lot more hidden than a PC

So here are a few tricks for those of you that would like to customize your Mac!
How to change the background on the Mac Login Screen:
Code:
Since the first way is not foolproof, I'm not going to say how to do it here. This way however, is foolproof on all Tiger and Leopard machines, as long as you haven't done too many things to the login screen.
1. Search for Terminal in the finder and open it. /Applications/Utilities/Terminal.app
2. Paste in this code, and change the second part of the code (the second path) to the path that your picture is at:
sudo defaults write /Library/Preferences/com.apple.loginwindow DesktopPicture "/Path/to/picture/you/want/to/use/image.jpg"
Do NOT move the picture, because Tiger or Leopard will be looking for that picture every time your computer starts up.
Another trick is making Safari open all new windows in a tab instead of an actual new window:
Code:
1. Open the terminal the same way you did before.
2. Make sure Safari is closed and quit, and paste in this code:
defaults write com.apple.Safari TargetedClicksCreateTabs -bool true
3. Now open Safari and done!
If you would like to revert the code with Safari, just change the last part (true) to false and paste it into the terminal.
I'll be updating this thread sometimes, but for now, I have to go!
Use these tricks wisely~
