Hello,  
I followed the excellent documentation provided by John\_lehr for installing on a MacBook with Catalina. I built the sleuth kit 4.11.1 and then Autopsy 4.19.2. However, when launching autopsy, I get an error linked to a mismatch in the JNI schema. It seems that the sleuthkit builds with a Java Runtime class file version 61.0, whereas my liberica bell jdk only recognises versions up to 52.0.  
Has anyone had this issue?  
Regards,

Hello,  
I rechecked thread from question from Jeff "Unable to get autopsy to start on MAC v 10.14.6 and found the answer to my problem: I had not uninstalled the openjdk.  
I did this from brew (with the --force option), reset the symbolic link in /usr/local/opt/openjdk to point to the liberica jdk, rebuilt the sleuthkit, and finally reinstalled autopsy 4.19.2 with “sh unix\_setup.sh”.  
I now have a full menu to create new cases on my macbook pro under Catalina 😃  
Thanks to the community !
