Option 1: Use the uninstaller
Go to the "Antares Audio Technologies" folder within your Applications folder, open the specific Antares plugin folder, double-click on the included uninstaller utility, and follow the instructions in the Terminal screen prompt.

If you have an older Antares plugin that does not have an included uninstaller utility, please use option 2 below to uninstall the plugin.
