Lost Audio iMac
This started when I was running Mojave on my Late 2013 iMac, The audio just went away. I reset the Pram and the smc but none of them were successful. Hoping that installing Catalina might help I installed it. Still no audio but I did lose some older programs that I frequently used. Any further suggestions as to what actions might help?
