How do I Uninstall and Reinstall my device drivers for the StudioLive on a Mac?

Why would I need to Uninstall & Reinstall my FireStudio drivers?

  • My Universal Control crashes when I launch it
  • My device Device window is not opening properly or not opening at all
  • My Universal Control launch window displays driver version "0.0.0.0"
  • My OSX just updated and my StudioLive no longer connects over FireWire

 

Answer:

Sometimes drivers do not install properly and can cause numerous issues with the functionality of your device. This is usually caused by certain files not being overwritten properly, older files from previous installs causing conflicts, or updates to your OS System 'breaking' the driver communication. These issues can normally be resolved by simply manually uninstalling the driver and software before installing the new version.

Uninstalling Universal Control ('Classic' Mixer version) using the Uninstaller application

 NOTE: Since the release of Universal Control 1.7.4, we now have an uninstaller for OSX (10.6.8 and later ONLY) which will remove all Universal Control and Firestudio related files (just as a manual uninstall would). Download Universal Control 1.7.x or above for Mac, double click on the Presonus_Universal_Control_17.dmg that you downloaded, and run the Un-installer first., then continue with the uninstall and re-install process starting with the section Removing .bom and .plist files below, and making sure to do the Disk Permissions Repair and PRAM reset steps.

NOTE: On OSX 10.8 and later, you may need to temporarily disable Gatekeeper to allow the uninstaller to open and run. See here for info: http://support.apple.com/en-us/HT5290

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

Manually Removing StudioLive / FireStudio family Drivers and Software

1. Disconnect your StudioLive / FireStudio Family interface

2. Double click on MacHD to launch a new finder window. The following list includes every possible file that may have been installed on your Mac, depending on which driver versions you have installed. If you do not see one of these files, do not be alarmed. 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
  • 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
  • MacHD/Library/Audio/MIDIDrivers/PAEFireStudioMIDIdriver.plugin
  • MacHD/Library/Preferences/PaeFireStudio.startup
  • MacHD/Library/Receipts/PreSonusUniversalControl.pkg
  • MacHD/Library/Startup Items/PaeFireStudio
  • MacHD/System/Library/Extensions/PaeFireStudio.kext

(If you are using OSX 10.7 Lion or 10.8 Mountain Lion, 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 next 4 files)

  • MacHD/Users/YOUR USERNAME /Library/Caches/Juce/jucAppLock_Universal Control
  • MacHD/Users/YOUR USERNAME/Library/Caches/Juce/Universal Control
  • MacHD/Users/YOUR USERNAME /Library/Preferences/FireControlSettings.settings
  • MacHD/Users/YOUR USERNAME/Library/PreSonus

Removing .bom and .plist files

For example, you are looking for:
