Question

After doing today's 3.5.0 update and the firmware update -- my 2-month old Quantum 2626 is not found.... 

Now my new iMac running Big Sur 11.3.1 will not see the Quantum 2626 that was working perfectly for months...  
I've uninstalled and reinstalled 3-times - no change. 
** MY STUDIO IS DEAD UNTIL SOMEONE HELPS ME. CALL PLEASE. 

I may have misunderstood, but the Baton Rouge office said they don't help studios like this... "whaaaaa" 

Answer 1

I figured it out    Security lockouts on MAC OS Big SUR 11.13.1   (a newer feature) - all okay now

* old studio guys could use a warning on that MAC feature, makes PreSonus update instructions look a bit foolish...
