AU migration guide

How to move Audio Units to a new Mac

If you use Logic Pro, MainStage, GarageBand, Ableton Live, or another Mac DAW, your Audio Unit plugins are a major part of your setup. Before moving to a new Mac, create a reliable inventory so you know what needs to be reinstalled.

Do not rely on memory during a studio rebuild.

A new computer is a good time to clean up your plugin library, but it is also easy to forget the tools your projects depend on. Start with a clear inventory, then rebuild intentionally.

Audio Units usually need proper installers

Audio Units often include more than a single component file. Presets, support files, license managers, content libraries, and system permissions can all matter. Reinstalling from official installers is usually cleaner than manually copying files.

Common AU location

Audio Unit component files are commonly found in /Library/Audio/Plug-Ins/Components on macOS. FX Locker helps you scan installed plugins and keep a record before you migrate.

Do not forget license managers

Many Mac plugins require iLok, vendor login apps, serial numbers, or account-based activation. Save these notes while you still have access to the old Mac.
