Hi, this is my first time using a digital forensics tool and am encountering an error while running autopsy: org.netbeans.InvalidException: StandardModule:org.sleuthkit.autopsy.core jarFile: /Users/Autopsy/autopsy-4.14.0/autopsy/modules/org-sleuthkit-autopsy-core.jar: java.lang.IllegalArgumentException: java.lang.reflect.InvocationTargetException The docs say to check the version in the messages.log file (which I cannot find) but with a java -version command, this is my output: openjdk version “1.8.0\_252” OpenJDK Runtime Environment (build 1.8.0\_252-b09) OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode) It seems my version differs where “252-b09” should be “232-b10” and am unsure as to how to change versions. Again, I’m very new to digital forensics and any help is appreciated. ---

The InvocationTargetException is usually an indication that a later version of Java is being used. You should be able to find the messages.log file in ~/Library/Application Support/autopsy/dev/var/log. The first 20 lines or so of that log will tell you which version of Java is being used. ---

Thanks for your response! Although I found that autopsy is not located in ‘Application Support’. Assuming the version is newer (252), how would I go about downgrading to the required version (232)? Again thank you, as I am a newbie to this. ---

There should be no need to downgrade to 232. I’m running 252 on a Linux box just fine. What do the first ~20 lines of your messages.log file look like? ---

I do not see a folder named ‘autopsy’ under ‘Application Support’ and therefore cannot find messages.log. ---

If you try to use the brew sleuthkit package, you will receive the error. Despite the installation instructions for Mac, you need to build sleuthkit from source. ---

Ok, I believe I read that from another thread but am unsure **how to build sleuthkit from source vs using brew**. I’m on Mac OS **Catalina** 10.15.4 using **zsh** shell (can change to **bash** if it helps). Thanks for response, I am new to this. ---

I solved the issue by using the new docs you posted for Mac found in another thread: [https://slo-sleuth.github.io/tools/InstallingAutopsyOnMacOS.html](https://slo-sleuth.github.io/tools/InstallingAutopsyOnMacOS.html) Thanks!!!
