Hey there,
so currently i'm facing problem in using Volatility 3 to analyse the ram dump file from MacOS Monterey 12.6 build 21G115, I had successfully created the symbol table for that OS version:
./dwarf2json mac --macho /Library/Developer/KDKs/KDK_12.6_21G115.kdk/System/Library/Kernels/kernel.dSYM/Contents/Resources/DWARF/kernel --macho-symbols /Library/Developer/KDKs/KDK_12.6_21G115.kdk/System/Library/Kernels/kernel > 12.6.json

After that I copied 12.6.json to /path_to_volatility3/symbols/mac/ directory.

ISFinfo shows:
python3 ./volatility3/vol.py isfinfo

It looks like ok, but any operations with image (mac.bash/mac.lsof/mac.pstree and etc.) don't work:

So it did identify the correct banner, but we then immediately try to use a structure that wasn't present:

It's not clear if this structure's name has changed, or it was removed (or possibly if the symbol table was generated incorrectly, but it doesn't look like it). We'll need to do some investigation to figure out what the problem is. The vm_map_object type is one that we override with a custom handler, and it appears the custom handler isn't finding the original definition in the JSON. I've asked @atcuno to see whether the vm_map_object structure was renamed or removed from recent mac kernels...

Ping @atcuno, before this times out in a couple months, could you please check about the vm_map_object in the mac symbol tables?

@atcuno The stale ticket just got added, which means it's been a couple of months since I asked. Have you had a chance to check out what's going on with the symbol tables and the vm_map_object symbol?

This structure was removed from the kernel, as well as many related vm_map ones.

The old/new versions are here :

Here is an article brieflly talking about it :

I was planning to update the framework, but It's gonna need more time and analysis to fix it. It mostly impacts mac.malfind.

@Abyss-W4tcher thanks for the analysis! Perhaps @atcuno or @gcmoreira can help out now we know what it is?

Hi, I will propose a patch in a PR soon, it's only in my fork right now.

I inform any dev here, to avoid potentially duplicating the same work 😃
