Select Local Disk nothing Detected | Mac Catalina

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:

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,
