Use the Audio Units Manager
Logic Pro uses the Apple Audio Units Validation Tool to ensure that only plug-ins that fully
comply with the Audio Units specification are used in Logic Pro. This minimizes problems that
may be caused by third-party Audio Units plug-ins. The Audio Units validation process takes
place automatically when Logic Pro is first opened, when an updated version of Logic Pro is
installed, and when you install new Audio Units plug-ins, or update existing ones. The results of
the validation scan are shown in the Compatibility column of the Audio Units Manager window.
The Audio Units Manager is only available when Show Advanced Tools is selected in the
Advanced preferences pane.
Any Audio Units plug-ins that fail the validation test can be manually enabled in the Audio Units
Manager window. You can also disable Audio Units plug-ins that you don’t want to use, even if
they pass the validation scan.
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.
