Installation:
This item is an extension, drag it onto a closed System Folder, and it will automatically be placed into the Extensions folder, where it belongs. When the computer is restarted, the extensions should take effect. In some cases there is a PowerPC version of the program, which you should use on any Mac with a PowerPC processor in it. Use the regular version for older 68k Macs. In cases where there is only one version, it will work on just about any Mac. Additional requirements are listed with the files. Note: If the computer's sound is turned all the way down, extensions that play sounds won't be noticeable.

Removal:
Just remove it from the Extensions folder of your System folder, and restart your Mac. It is that simple!
