mac cubase won't start

I can’t get cubase to start on a mac. People suggest deleting the preferences, but I don’t know where they are, and this looks like a solution for PC’s, I don’t know if it applies to mac.

aNy ideas please ?

btw, I found and deleted the preferences, no difference

hello Steinberg, can somebody please help me with this ?!?

anyone else getting zero response from steinberg support ? useless !!
