Installed GarageBand Jam Pack 2 Remix Tools but can't find it The installer installed it to my hard drive but I don't see an icon that I'm supposed to click on to access it.  Can anyone help me understand this
You access the instruments and loops from within the GarageBand application. Instruments will be added to the pane on the right, under the Software Instruments: Browse tab.

Loops will be in the Loop Browser. In GarageBand, pull down the Control menu and choose "Show Loop Browser".
