Hello There,

I hope you are well!

I am reposting in this category after not recieving any assitance and realising it may be because it was in the wrong section.

Anyway, I am trying to get Autopsy to scan an old Mac. I have managed to get Autopsy setup and working - to a point. When I try to add a data source, nothing comes up. Refreshing does nothing.

I did find this for Linux:

I don’t know how to execute Autopsy with admin privileges. I’m using Linux (Debian). This is probably a rookie question, but I really don’t know how. Any pointers? Additional information: when I try to run from root, I get this: ./…/platform/lib/nbexec: WARNING: environment variable DISPLAY is not set I set my u…

But of course this relates to Linux. But I wonder if I can add something similar to the Shell Script in Automator that will give me root access or the MacOS equivalent - I suspect it must be a permissions issue?

I tried adding sudo -s to the command line in Automator to no effect. I have just tried adding Autopsy into the Security & Privacy but that hasn’t helped either.

Can anybody help?

Thank you in advance,

For anybody else in this situation, using **Logical Mode** allows the user to select whatever disk they desire.
