Install Autopsy in Mac Studio 2022

Autopsy Help
1

Hello,

I’m trying to finish installing Autopsy on my Mac Studio 2022 and on the step where you have to lunch the script (sh unix_setup.sh) I get following error:

Checking prerequisites and preparing Autopsy:
---------------------------------------------
-n Checking for PhotoRec…
ERROR: PhotoRec not found, please install the testdisk package.

The steps I’m following os from the Cyber Social Hub: Installing Autopsy on macOS Big Sur – Cyber Social Hub

Anyone who could help me with this?

Many thanks in advance.

Did you install test disk/photrec as the preeeq in the install docs state? You need brew to install it.

Hi Mark,

thanks for the feedback. I actually followed all steps specified in the link I posted.
% brew install testdisk

As I’m working on a new machine I had to install all from ZERO (brew included) :slight_smile:
But it seems that I still cannot proceed from the step I mentioned, it’s still NOT FOUNDING PhotoRec from any reason… :frowning:

Cheers!!

Hi again Mark,

this is the output when I chekc the installed versions of PHOTREC and TESDISK:

So I ran into this problem with my M1 Max Macbook Pro. Not sure if you still need help, but thought I’d leave my solution here for anyone else.

I took a look at ./unix_setup.sh and worked out it was failing due to checking for a specific simlink. It seems homebrew only sets up its own simlink. I just went and created the required simlink pointing to the homebrew simlink, which required sudo. After that, autopsy managed to configure.

Here’s the exact command I used. First path is the homebrew simlink on my device and the second path is the simlink the script expected to find that will be created.

sudo ln -s /opt/homebrew/bin/photorec /usr/local/bin/photorec

Your photorec may be installed somewhere else, but you can check that like this.

% which photorec
/opt/homebrew/bin/photorec

I then had some trouble running the executable, but that seemed to be unrelated to this issue.
