In order to uninstall ERA Bundle plugins from your macOS system, you will need to delete the plugin files from their folders.
After the product deactivation, close your DAW or NLE and,
a) Go to the Finder and click on the "Go" menu,
b) Click on "Go to folder..." and paste in one of these file paths:
- /Library/Application Support/Avid/Audio/Plug-Ins
- /Library/Application Support/Accusonus/ERA-Bundle 5/AudioCleanUpAssistant/VST3/
c) Then, in each folder, find the ERA Bundle plugin that you want to uninstall, and move it to the Trash.
