Question

I have a StudiLive 16.4.2 and I've changed computers.  It won't link to my iMac but will link perfectly to my Macbook Pro.  I am running Yosemite 10.10.5 on a 2012 3.06GHz iMac i3 with 16gb of RAM.  I've downloaded 1.72 and 1.74 Universal Control but no interface comes up.  I hear it click in the speakers when I plug the firewire in but the interactive display doesn't come up.  What am I missing.  It was plug and play with my Macbook Pro and the old Mac Mini I had before.  

The board says "No Driver - Unlinked" but it always says that. Firmware is 1.50a on the console.  I scroll through firewire link ID and still nothing.  U.C. says Driver Version 0.0.0.0 5773.  I check the firmware and it says up to date.

I'm at a loss.  I've searched through Knowledge Base but the search option is a little sloppy and too broad.  

HELP!!

See the article below.  It should take you through how to recognize your mixer is working correctly and including driver troubleshooting methods:

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) 
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, 
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 !!! 
That completes the install !!!!

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.
