To load a newly installed plug-in within Ableton Live (Mac OS X), you can follow these steps:
- Go to Live menu > Preferences.
- Click the 'File Folder' tab.
- Under the 'Plug-In Sources' section, make sure that either the 'Use Audio Units' or the 'Use VST Plug-In Folders' option is enabled.
- Click 'Rescan' to rescan the plug-ins folder.
- Close this window.
You should now be able to access the plug-in from with the Plug-in Browser, and from within FX section of your audio tracks.
