Error with display

I’m trying to run root on my computer, and I receive this error message, “can’t figure out DISPLAY, set it manually”. What can I do to fix this?


Which OS?

Cheers, Bertrand.

Hi Bertrand,

Os X Yosemite 10.10.5

I think you should install XQuartz.
Alternatively, you can try to search this forum (or even Google) for the error message you have, I’m sure you will find a solution (it is one of the reason why the Forum is useful…)

Cheers, Bertrand.
