How do I completely remove Studio 192 software on Mac OS X?

Studio 192 does not use a device driver on Mac OS X, it operates as a class-compliant interface with UC Surface as control for routing and effects. Should you need to remove Studio 192 software, for 99% of the time, the simplest way to uninstall the software is to drag the UC Surface application to the trash.

However should you feel the need to completely uninstall all software on your system, you can do a "Complete Uninstall"

This article is not to be confused with a similar knowledge base article for StudioLive FireStudio Products from which this article is derived. As of UC Ai (UC Surface) (version 1.4.1 build 35113) now contains both the 1394 driver for the FireStudio Series and the USB Audio software for the Studio 192. For previous versions of UC Surface, an uninstaller is available. With the addition of the Studio 192, the uninstaller will not work, for a complete uninstall, it must be done manually. 

This tutorial is going to remove both because some of the software is shared between the two product lines.

Studio 192 - Mac OS X - Complete Uninstall

If you do need to do the manual uninstall by hand, the instructions are as follows:

Manually removing Firestudio, StudioLive, StudioLive-AI Drivers and UC Surface / Studio 192 Software

1. Disconnect your FireStudio Family / Studio 192 interface and make sure neither Universal Control or Universal Control-AI are running in the dock. Quit them if necessary.

2. Double click on MacHD to launch a new finder window. The following list includes every possible Firestudio related file that may have been installed on your Mac, depending on which driver versions you have installed previously. If you do not see some of these files, it's not a problem. The files are listed by location tree.

For example, to locate the MacHD/Library/Preferences/PaeFireStudio.startup file, you will double click on MacHD and Open the Library folder. In the Library folder, you will open the Preferences folder where you will find the PaeFireStudio.startup file. This is the file you will move to the Trash.

3. Delete the following from your computer (note: some files will require that you type in your administrative password):

  • MacHD/Applications/Universal Control AI
  • MacHD/Applications/Universal Control
  • MacHD/Applications/FireStudio Control Console
  • MacHD/Applications/FireControl
  • MacHD/Applications/FireStudio Lightpipe Mixer
  • MacHD/Applications/StudioLive

 ---

  • MacHD/Library/Application Support/PaeFireStudio
  • MacHD/Library/Application Support/PreSonus/Devices
  • MacHD/Library/Audio/MIDIDrivers/PAEFireStudioMIDIdriver.plugin
  • MacHD/Library/LaunchDaemons/tc.tctechnologies.PaeFireStudio.plist
  • MacHD/Library/Preferences/PaeFireStudio.startup
  • MacHD/Library/Preferences/PreSonus/Universal Control
  • MacHD/Library/Preferences/PreSonus/Universal Control (x64)
  • MacHD/Library/Receipts/PreSonusUniversalControl.pkg
  • MacHD/Library/Startup Items/PaeFireStudio
  • MacHD/Library/StartupItems/PaeFireStudio

---

  • MacHD/System/Library/Extensions/PaeFireStudio.kext

 ---

In OS X version 10.8 or later for Studio 192 the User Library folder is hidden. To get to it, with Finder open click the GO menu at the top, or control-click on Finder in the Dock, then select "Go To Folder" and enter: ~/Library

This is necessary for deleting the following files. Again, if you do not see some of these files, it's ok:

  • *MacHD/Users/YOUR USERNAME/Library/Application Support/Presonus/Studio 192
  • MacHD/Users/YOUR USERNAME/Library/Application Support/Presonus/Universal Control AI
  • MacHD/Users/YOUR USERNAME /Library/Caches/Juce/jucAppLock_Universal Control
  • MacHD/Users/YOUR USERNAME/Library/Caches/Juce/Universal Control
  • MacHD/Users/YOUR USERNAME/Library/Caches/com.presonus.ucapp
  • MacHD/Users/YOUR USERNAME/Library/Preferences/FireControlSettings.settings
  • MacHD/Users/YOUR USERNAME/Library/Preferences/PreSonus/Universal Control
  • MacHD/Users/YOUR USERNAME/Library/Preferences/PreSonus/Universal Control (x64)
  • MacHD/Users/YOUR USERNAME/Library/Preferences/PreSonus/FireStudio
  • MacHD/Users/YOUR USERNAME/Library/PreSonus/Firestudio

*******************************************************************

Removing .bom and .plist files

  1. With Finder open click the GO menu at the top, or control-click on Finder in the Dock
  2. Select "Go To Folder"
  3. Paste or type in this file path and press enter:       /private/var/db/receipts
  4. In the folder that opens, find the files that have Universal Control in the label and move them to the Trash.

The potential files you are looking for are:

  • com.PreSonus.pkg.Universal Control (.bom and .plist)
  • presonus.pkg.Universal.Control.AI.audio_driver (.bom and .plist)
  • presonus.pkg.Universal.Control.AI.controlpanel (.bom and .plist)
  • presonus.pkg.Universal.Control.AI.midi_driver (.bom and .plist)
  • presonus.pkg.Universal.Control.AI.presets (.bom and plist)

And again, if you do not see some of these files, it's not a problem. What files show up will depend on which versions of Universal Control you may have installed previously.
