asked Jan 6, 2017 in Classic Mixers by davidej123 (120 points)
Hello,

I have a Presonus StudioLive 16.4.2 (non-AI) mixer. I purchased it in 2013 and love it dearly. I have always used it with the same MacBook Air, detailed below. Unfortunately, after updating the Mac OS to Sierra last month, my 16.4.2 no longer appears in Universal Control or Capture. Could you please help me get my interface working again - anxious to record again!

Thank you,

Jeff

MacBook Air (13-inch, Mid 2012)

Processor: 1.8GHz Intel Core i5

Memory 8 GB 1600MHz DDR3

OS: Sierra Version 10.12.1

StudioLive 16.4.2 Classic

Firmware: 1.50a

Build 190

This is the fix: 
first: Unplug your Presonus from the Mac Computer firewire port:

Check your mixer in "System" to make sure it is on Device I.D. #0 !!!

Follow Procedures to" UNINSTALL universal control" 
Remove files as explained,( I followed all procedures) 

Remove all entities of Universal Control, EMPTY THE TRASH
SHUT down, (Not Restart).

Start Up MAC, 
goto : Applications / UTILITIES 
Open "Disk Utility" 
run "First Aid" or click on "Repair Permissions".

SHUT DOWN.

Restart Mac, 
while holding these keys down on the keyboard: 
"Command + Option + R + P" 
wait until you hear the 2nd Start Chime from your Mac, 
then release the keys. 
This "Resets"/ Zaps Your PRAM.

SHUT DOWN.

Restart Mac, 

Turn off your "FIRE VAULT" in Sys Prefs
Open latest dmg package of Universal Control from Presonus ((1.7.4.2)) 
INSTALL the package to your Computer. 
do NOT shut down at this point:

This is the part that is NOT in some instructions: 
GOTO : System Prefs/ Security+Privacy,/ General, 
There will be a note that says something like 
"T.C. Electronics was blocked while install......" with a button.: "ALLOW" ?

Yes ALLOW this !!!  Click on ALLOW,
That completes the install !!!!

( New Mac OS has protection with Kernels being installed,"KEXT", its a security issue)

RE plug your Firewire into the Mac computer, and wait a minute.

Check your System Prefs / SOUND, 
You should see the Presonus as a choice again.

Upon restart or Shut down and starting up again you run into the same problem: 
(not seeing the mixer on the Mac) 
go through the procedure AGAIN meticulously.

It worked for me after many restarts/shut downs/ and fuse box switched off, then on before start up.

Presonus Studio Live 16.4.2 (Classic) firmware 1.50a build 190 
Universal Control 1.7.4.2 
Mac mini OSX 10.13 High Sierra 
Studio ONE 3.5.4.45392
