FireStudio Family - How do I Uninstall & Reinstall my FireStudio drivers on a Mac computer?

Why would I need to uninstall & reinstall my FireStudio drivers?

  • I have a Red Exclamation Mark on Universal Control Icon
  • My Universal Control crashes when I launch it
  • My device window is not opening properly or not opening at all
  • My Universal Control launch window displays driver version 0.0.0
  • I have updated my OSX to 10.7 and need to Install FIreControl for the FireStudio 2626
  • I have installed an outdated Universal Control driver on OSX 10.7+ and StudioOne is crashing

 

Answer:

There is a known issue that prevents the FireStudio family driver from properly overwriting earlier versions of its files on some systems. This can create a driver conflict that prevents the control panel from working properly. A complete manual uninstall of the driver can resolve this issue.

 

Please note: Your FireStudio family interface should have a solid blue sync light and will be recognized within the AudioMIDI setup utility as an available audio and MIDI device if a driver conflict is the cause of the errors listed above. This FAQ will guide you through the complete uninstall process and well as downloading the latest driver from the PreSonus website and installing in on your Mac.

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

 NOTE: Since the release of Universal Control 1.7, 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 for Mac here, find your device and download the .dmg file.  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. * If you are installing the FireControl for the FireStudio 2626 and removing an older version of Universal Control please continue at number 1 below.

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

Remove FireStudio family Driver Files

 

1. Disconnect your FireStudio Family interface.

2. 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 /Library/Preferences/PaeFireStudio.startup file, you will double click on MacHD and then Open the Library folder.

 

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

/Applications/Universal Control

/Applications/FireStudio Control Console

/Applications/FireControl

/Applications/FireStudio Lightpipe Mixer

/Applications/StudioLive

/Library/Application Support/PaeFireStudio

/Library/Application Support/PreSonus

/Library/Audio/MIDIDrivers/PAEFireStudioMIDIdriver.plugin

/Library/LaunchDaemons/tc.tctechnologies.PaeFireStudio.plist"

/Library/Preferences/PaeFireStudio.startup

/Library/Receipts/PreSonusUniversalControl.pkg

/Library/Startup Items/PaeFireStudio

/System/Library/Extensions/PaeFireStudio.kext

(If you are using OSX 10.11 El Capitan, 10.10 Yosemite, 10.9 Mavericks, 10.8 Mountain Lion or 10.7 Lion, the User Library folder is hidden.

Locating hidden Library folder on Mac

 

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)

/Users/YOUR USERNAME /Library/Caches/Juce/jucAppLock_Universal Control

/Users/YOUR USERNAME/Library/Caches/Juce/Universal Control

/Users/YOUR USERNAME /Library/Preferences/FireControlSettings.settings

/Users/YOUR USERNAME/Library/PreSonus

If you have other PreSonus products installed they may be shown in this folder. For the purpose of removing FireStudio you'll want to delete the following folders found inside the /Users/YOUR USERNAME/Library/PreSonus folder. 

/Users/YOUR USERNAME/Library/PreSonus/FireStudio

/Users/YOUR USERNAME/Library/PreSonus/Universal Control (x64)

/Users/YOUR USERNAME/Library/PreSonus/Universal Control (note this folder may not show up on Mac OS X 10.9, 10.10 or 10.11 or later, that's ok)

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

Remove .bom and .plist files

*If you've done the UC 1.7 uninstall script method above, and these files are not there, you can proceed with the next section.

Note: if you use OSX 10.11 El Capitan, 10.10 Yosemite, 10.9 Mavericks, 10.8 Mountain Lion, 10.7 Lion or 10.6 Snow Leopard, you also need to do the following:

a) Right Click the Finder

b) From the pop-up window select Go To Folder

c) Paste or type in this string:       /private/var/db/receipts

d) In the folder that opens, find the files that have Universal Control in the label and move them to the Trash.
