Hello There,

I hope you are well!

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

I did find this:

> [@Local drives were not detected](https://sleuthkit.discourse.group/t/local-drives-were-not-detected/2372):
>
> When I’m on the “Add Data Source” screen, I try to select a disk but it says “Local drives were not detected. Auto-detection not supported on this OS or admin privileges required”. 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 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? It is saying somethging about Lastpassin the error message and I found something to that effect on Github, but not sure if its right or what to do with it.

Can anybody help?

Thank you in advance,
