How to stop Universal Audio (UA Audio) mini application manger from launching at startup

Problem with Application Manager

When you install UA Audio, it will automatically install a package manager that sits on the upper right-hand menu on your finder.

Disable Auto Launch

Open up Terminal on macOS and open this file. Note, you may need to use sudo to ensure you have the necessary permissions.

sudo nano /Library/LaunchAgents/com.uaudio.ua_mixer_engine.plist

Step 2 - Edit .plist file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<!-- LaunchAgent -->
<plist version="1.0">
        <dict>
                <key>Label</key>
                <string>com.uaudio.ua_mixer_engine</string>
                <key>Program</key>
                <string>/Library/Application Support/Universal Audio/Apollo/UA Mixer Engine.app/Contents$
                <key>RunAtLoad</key>
                <false/>
                <key>ProgramArguments</key>
                <array>
                        <string>/Library/Application Support/Universal Audio/Apollo/UA Mixer Engine.app/$
                        <string>-silent</string>
                </array>
        </dict>
</plist>

Repeat This Process Again

sudo nano /Library/LaunchAgents/com.uaudio.uad-meter.plist 
  GNU nano 2.0.6         File: /Library/LaunchAgents/com.uaudio.uad-meter.plist                          

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
        <dict>
                <key>Label</key>
                <string>com.uaudio.uad-meter</string>
                <key>Program</key>
                <string>/Applications/Universal Audio/UAD Meter & Control Panel.app/Contents/MacOS/UAD M$
                <key>RunAtLoad</key>
                <false/>
                <key>ProgramArguments</key>
                <array>
                        <string>/Applications/Universal Audio/UAD Meter & Control Panel.app/Contents/Mac$
                        <string>-h</string>
                </array>
        </dict>
</plist>

Step 3 - Reboot

Restart your computer and you're done.

sudo reboot
