Error message while trying to extract system volume from IPSW

[alreadyconfused]

Tried extracting it on a iMac 12,2 running sequoia 15.2

Traceback (most recent call last): File "/Users/ye/MetallibSupportPkg/metallib.py", line 8, in <module> metal_libraries.main() ~~~~~~~~~~~~~~~~~~~~^^ File "/Users/ye/MetallibSupportPkg/metal_libraries/cli.py", line 154, in main result = extract(args.extract) File "/Users/ye/MetallibSupportPkg/metal_libraries/cli.py", line 52, in extract return IPSWExtract(input).extract() ~~~~~~~~~~~~~~~~~~~~~~~~~~^^ File "/Users/ye/MetallibSupportPkg/metal_libraries/ipsw/extract.py", line 85, in extract return self._extract_system_volume() ~~~~~~~~~~~~~~~~~~~~~~~~~~~^^ File "/Users/ye/MetallibSupportPkg/metal_libraries/ipsw/extract.py", line 69, in _extract_system_volume system_image_path = self._decrypt_aea(system_image_path) File "/Users/ye/MetallibSupportPkg/metal_libraries/ipsw/extract.py", line 30, in _decrypt_aea result = subprocess.run( [ ...<6 lines>... capture_output=True, text=True ) File "/usr/local/Cellar/[email protected]/3.13.1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/subprocess.py", line 554, in run with Popen(*popenargs, **kwargs) as process: ~~~~~^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/Cellar/[email protected]/3.13.1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/subprocess.py", line 1036, in __init__ self._execute_child(args, executable, preexec_fn, close_fds, ~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ pass_fds, cwd, env, ^^^^^^^^^^^^^^^^^^^ ...<5 lines>... gid, gids, uid, umask, ^^^^^^^^^^^^^^^^^^^^^^ start_new_session, process_group) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/Cellar/[email protected]/3.13.1/Frameworks/Python.framework/Versions/3.13/lib/python3.13/subprocess.py", line 1966, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) OSError: [Errno 86] Bad CPU type in executable: PosixPath('/Users/ye/MetallibSupportPkg/metal_libraries/ipsw/bins/aastuff')

There's the error log.
