**I take no responsiblity if you mess up your mac**
Note you must be an adminstartor for most of these changes
Also more will be posted I'm feeling lazy.
Step 1: Geektool
Do a little research to fully understand Geektool.
After you read up try these different shells without quotations
"curl --silent "http://xml.weather.yahoo.com/forecastrss?p=02066&u=c" | grep -E '(Current Conditions:|C<BR)' | sed -e 's/Current Conditions://' -e 's/<br \/>//' -e 's/<b>//' -e 's/<\/b>//' -e 's/<BR \/>//' -e 's/<description>//' -e 's/<\/description>//'"
For more commands do a google search
another helpfull log to have is the crash log (Make sure you go to file not Shell) :
Step 2: Quicksilver
again do a little read up
its pretty simple just assign a hotkey to bring up the menu then type the name of whatever you want to find
kinda like spotlight but better
Step 3: Change the Dock Text
First go to /system/library/coreservices/dock.app <-- dont open dock.app but control click then show package contents
from there click contents/resources/english.iproj
Then drag dockmenu.strings to your desktop (it may ask you to authenticate type in your password)
once you have a copy of the dockmenu delete the one from the english.iproj folder.
open up the copy from the desktop and now you can change the text displayed from the dock.
there will be sort of like two columns the one on the left you dont wanna change, but teh one is qoutations you can change.
for example the first line reads:
TURN_HIDING_ON = "Turn Hiding On" ;
the part you can change is that
have some fun wit those and get creative.
When your done save it then drag it back into the english.iproj again authenticate
Now i believe all you have to do to see the changes is open up terminal then type
you may need to restart you computer I dont remeber.
Step 4: Open Up the Login Window While Logged In
go to /system/library/coreservices/loginwindow.app <--show package contents then click loginwindow
the terminal will run a command let it do its thing and in a second or two the login window will pop up. you cant move it but you can still click on it, to close it just close the terminal window
Step 5: Change the Finder Text
its best if you have photoshop or some photo editing program to do this step.
first go to /System/Library/Coreservices/loginwindow.app <--"Show package contents"
then go /System/Library/Coreservices/loginwindow.app/contents/resources
find the file 'MacOSX.tif"
Copy this file to your desktop then open it in your photo editing program.
next delete the old MacOSX.tif from the resources folder you may have to authenticate this just type in your password.
save your editing image and place it back into teh resources folder again your going to have to authenticate.
if you did this right restart you computer and log in agian then check the about this mac and your image should be changed to whatever you changed it to.
