Even when its main interface is not open, part of Loopback is running in the background so that its virtual audio devices can be active. If you simply delete the Loopback application, you may find it hasn’t been completely removed from your Mac.
Luckily, removing Loopback is easy, by using the Uninstall option in the Loopback app itself. Just follow these steps:
- If necessary, download Loopback again through this link: https://rogueamoeba.com/loopback/download.php
- Launch Loopback, and choose the “Uninstall…” command from the Loopback menu.
- Follow the prompts to uninstall Loopback then quit the application when finished.
- Now, to finish removing Loopback, place the Loopback application in the Trash and empty it.
When you've completed those steps, all Loopback devices on your system will be removed and the software will be fully uninstalled.
