Hi my Pegasus R4 wont mount with Mojave on Macbook mid 2015.
I have downloaded latest driver and Promise utility. It shows in system report in firewire tab as conected. The Promise utility just has tabs and dropdown menu but no window and won't open a window or recognise drive.
The R4 mounts fine on my son's Macbook Air running High Sierra. Some software I use requires me to use Mojave.
Can anyone help?
