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".
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.
Open latest dmg package of Universal Control from Presonus ((188.8.131.52))
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.
