Version 4 is a good Investigator Tool for using it with Mac OSx i gibe 3 and a half Stars for that.
If Forensic Lab get Mac Script Support and better Windows Investigating Tools i will give full 5 Stars.
Reporting system is nice and clean, like hole Application.
If you are a Investigator that use Sleuth kit and Autopsy do not await same Feature Set here in Forensic Lab you can do same Things but something you must do others.
This Tool is made for doing some Tasks very Simple but without a Script Engine you can only use what forensic Lab can do inside the App go first reading the manual or ask for a Demo
