Removing AP Extended audio driver

I tried all the steps you will find with a simple google search. Couldn't find the file. Turns out the file was very hidden and not in the normal places. I worked with Gemini for a few hours to reach a solution. I asked Gemini to summarize it below. Big picture, I had to find the original package that was downloaded and installed. I used the Terminal to find the files that had been installed in order to identify the driver name. I couldn't find the driver file using a normal Find even after revealing hidden files. I ended up using the final step below to have the Terminal delete it wherever it was.

So annoying. But thankful for AI to solving this issue.

Solution: How to Find and Uninstall the Hidden APAudioDriver.driverfrom the AnyMP4 Installer

If you've run the audio-recording-plugin.pkg installer (associated with the developer AnyMP4) and can't find the audio driver in the standard /Library/Audio/Plug-Ins/HAL folder, it's because the installer places the driver in a hidden, non-standard location.

The driver name is APAudioDriver.driver, and it is often installed directly into the root directory of your hard drive (/), but hidden from view.

Here are the two steps needed to locate and delete the file:

Step 1: Use Terminal to Identify the Package ID

First, we need to find the receipt that the installer left behind to confirm the Package ID.

• Open Terminal (found in /Applications/Utilities/).
• Run this command to find the most recently installed package receipts:

Bash

ls -lt /var/db/receipts/

• Look at the top of the list for a file that contains the name of the software. In this case, the file was com.anymp4.recorder-audio-plugin.pkg.plist, which confirms the Package ID is com.anymp4.recorder-audio-plugin.pkg.
• Run the pkgutil command to list the files installed by that package:

Bash

pkgutil --files com.anymp4.recorder-audio-plugin.pkg

• The output confirmed the driver was installed at ./APAudioDriver.driver, which translates to the root directory of your Macintosh HD.

Step 2: Locate and Delete the Hidden File

Because the file is hidden, you cannot see it by simply browsing the root folder.

Method A: Reveal Hidden Files in Finder (Easiest)

1. Open Finder.
2. Click Go > Computer.
3. Double-click your main hard drive (Macintosh HD).
4. Press the keyboard shortcut: Command + Shift + . (the Period key). This reveals all hidden files, which will look greyed out.
5. Look for the folder/file named APAudioDriver.driver.
6. Drag APAudioDriver.driver to the Trash and empty it.

Method B: Delete Directly via Terminal (Guaranteed)

If Method A does not work, use this powerful command to force-delete the hidden file.

1. Open Terminal.
2. Copy and paste this command and press Enter:

Bash

sudo rm -rf /APAudioDriver.driver

1. Enter your administrator password (typing is invisible) and press Enter.

After deleting the file using either method, restart your Mac immediately to complete the uninstallation and remove the driver from the Core Audio system.
