mac pro mid 2012 startup chime missing
Hi All,
I have just realised that my start-up chime is missing.
I have done some research & tried to get it back using Terminal & typing in the following :
sudo nvram StartupMute=%00.
However, this made no difference.
I also tried resetting the PRAM - but again, no sound.
Mac Pro Mid 2012
MacOS Mojave 10.14.6
Processor: 2 x 3.46 GHz 6-core Inter Xeon
Memory: 128GB 1333 Mhz DDR3
Startup disk : SSD
Graphics: Radeon RX 580 8 GB
Any ideas?
Many thanks in advance
