Apple Logic Pro 9 - Manual (Page 316)

Disabling Plug-ins
The Audio Units Manager also allows you to disable Audio Units plug-ins that you don’t
want to use in Logic Pro, even if they pass the validation scan. Simply deselect the
corresponding checkbox in the Logic or Nodes column to disable any plug-in. You can
store your choice of Audio Units plug-ins by clicking the Done button.
Click the Reset & Rescan Selection button to rescan a selection of plug-ins after installing
plug-ins/updaters or moving components in the Finder, while Logic Pro or the Audio Units
Manager is open. They will be activated automatically, if they pass the validation scan.
Note: If you press Control-Shift while opening Logic Pro, the Audio Units Safe mode will
be used. Only plug-ins that pass the validation test will be available; manually activated
plug-ins that failed the validation test will not be available.
