If you are using BIASFX, then you probably want to remove the existing plugins in this list that Apple already put into the track by default (click on each one and set to 'No Plug-in'), since they are likely redundant to BIASFX. It isn't exactly intuitive, but inside the 'Plug-Ins' section of 'Smart Controls', there is a smaller square box containing a list of current plugins. Note that GB uses the AU version of the plugin, not VST, although the same BIASFX install will install both AU and VST versions of the plugin, as per above. There is a 'Plug-Ins' section in the 'Smart Controls' (you can Show/Hide the 'Smart Controls' under the 'View' menu). Regarding GarageBand, it should already see the plugins, assuming you start GB after installing the plugins. User-level install or manual copy: /Users//Library/Audio/Plug-Ins System-level install by install program: /Library/Audio/Plug-Ins Keep in mind that the BIASFX installer will install both AU and VST versions of the plugin under the system-level path below (AU plugin under the 'Components' subfolder, and VST plugin under the 'VST' subfolder):

In general these are the two places that plug-ins go, depending on how they are installed.
