AutoMacTC is a modular forensic triage collection framework designed to access various forensic artifacts on macOS, parse them, and present them in formats viable for analysis.

The output may provide valuable insights for incident response in a macOS environment. Automactc can be run against a live system or dead disk (as a mounted volume.)


  • Python 2.7 (Mac systems ship natively with Python 2.7. Python 3 support will be included in a future update)
  • MacOS target systems, for live collection (successfully tested on macOS major releases 10.11 through 10.14)
  • MacOS analysis systems, for triage against a mounted disk image

Basic Usage

At its simplest, you can run automactc with the following invocation. Note: automactc requires sudo privileges to run, and should be called specifically from /usr/bin/python2.7 to ensure full functionality.

sudo /usr/bin/python2.7 -m all

This will run all modules (-m) with default settings, i.e. – default input directory will be /, or the root of the current volume – default output directory will be ./, or the working directory from which automactc is run (NOT the location of the script) – default prefix for output filenames will be automactc-output – default behavior is to populate a runtime.log for debugging and info – default format for individual artifacts output files is CSV – default CPU priority is set to low – default behavior on completion is to compress all output files to tar.gz

In order to list all available modules and do nothing else, simply run: -l

The inputdir and outputdir can be specified with the -i and -o flags, respectively. -i / -o /automactc_output -m all

Modules can be specified for inclusion or exclusion on a per-module basis. In other words, you can INCLUDE specific modules, such as pslist, bash, and profiler: -m pslist bash profiler

Or, you can exclude specific modules, to run all EXCEPT those specified, such as dirlist and autoruns: -x dirlist autoruns

Output Control

For every module, automactc will generate an output file and populate it with data. The output file format defaults to CSV, but can be toggled to JSON with the -fmt flag. It is not currently possible to specify output format on a per-module basis. -m all -fmt json

Upon successfully populating the output file with data, the file is rolled into a .tar archive that is generated when automactc completes its first module. Upon completion of the last module, automactc will GZIP the .tar archive to .tar.gz.

The name of the tar archive follows the following naming convention:


The first field, prefix, can be specified at runtime with -p. If unspecified, the prefix is set to automactc-output. The other fields are populated from data gathered at runtime. This is useful when running automactc on several systems for a single incident. -m all -p granny-smith

While the default behavior is to generate a tarball, use of the -nt flag will prevent the creation of a tar archive and will leave the output files as-is in the output directory. -m all -p granny-smith -nt

Advanced usage

By default, automactc populates verbose debug logging into a file named prefix,hostname,ip,runtime.log. You can disable the generation of this log with: -m all -nl

By default, automactc will print the INFO and ERROR log messages to the console. To run automactc in quiet mode and write NO messages to the console, use -q. INFO messages include program startup messages, one message per module start, and completion/cleanup messages. -m all -q

To print DEBUG messages to the console along with INFO and ERROR messages, use the -d flag. -m all -d

Automactc runs with the lowest CPU priority (niceness) possible by default. It is possible to disable niceness and run at a normal priority with the -r flag. -m all -r

Automactc can also be run against a dead disk, if the disk is mounted as a volume on the analysis system. Once mounted, run automactc with the appropriate inputdir (pointing to the Volume mount point) and -f to toggle forensic mode ON.

NOTE: for a live system, if you wish to collect dirlist on mounted peripheral devices, you can use -f with -i /, else dirlist will not recurse further into mounted /Volumes. -i /Volumes/mounted_IMAGE/ -o /path/to/output -f -m all

Dirlist Arguments

Directory Inclusion/Exclusion

It is possible to limit dirlist recursion to specific directories with the -K flag. By default, dirlist will attempt to recurse from the root of the inputdir volume unless otherwise specified with this flag. Multiple directories can be specified in a space separated list. -m dirlist -K /Users/ /Applications/ /tmp

It is also possible to exclude specific directories from dirlist recursion with the -E flag. -m dirlist -E /path/to/KnownDevDirectory

By default, the following directories and file are excluded on live systems:

/.fseventsd (to reduce output verbosity)
/.DocumentRevisions-V100 (to reduce output verbosity)
/.Spotlight-V100 (to reduce output verbosity)
/Users/*/Pictures (to avoid permissions errors)
/Users/*/Library/Application Support/AddressBook (to avoid permissions errors)
/Users/*/Calendar (to avoid permissions errors)
/Users/*/Library/Calendars (to avoid permissions errors) /Users/*/Library/Preferences/ (to avoid permissions errors)

By default, the following directories are excluded when running forensic mode against a mounted image:

/.fseventsd (to reduce output verbosity)
/.DocumentRevisions-V100 (to reduce output verbosity)
/.Spotlight-V100 (to reduce output verbosity)

Any additional directories to exclude will be appended to this default list, unless you provide the -E no-defaults argument first, in which case only your specified directories will be excluded. -m dirlist -E no-defaults /path/to/KnownDevDirectory


The hashing arguments below can be used for BOTH dirlist and the autoruns modules.

By default, the dirlist module will hash files only with the sha256 algorithm. If you wish to use both the SHA256 and MD5 algorithms, use -H sha256 md5. If you wish to use only md5, use -H md5. If you wish to use neither, use -H none. NOTE: If you run the dirlist module against a dead disk with hashing enabled, this currently takes a LONG time to run. -m dirlist -H sha256 md5

By default, the dirlist module will only hash files with sizes under 10mb. To override this setting and hash files under a different size threshold, the threshold can be changed with the -S flag in number of megabytes. NOTE: increasing the size threshold will likely increase the amount of time it takes to run the dirlist module. For example, to hash files up to 15MB: -m dirlist -S 15

Bundles, Signatures, Multithreading

By default, the dirlist module will NOT recurse into bundle directories, including the following:

‘.app’, ‘.framework’,’.lproj’,’.plugin’,’.kext’,’.osax’,’.bundle’,’.driver’,’.wdgt’

To override this setting, use the -R flag. NOTE: this produces a far higher volume of output and takes significantly more time. These bundle directories will be configurable in a future update.

By default, the dirlist module will check codesignatures for all .app, .kext, and .osax files found. To prevent the dirlist module from checking any code signatures, use the -NC flag. This argument can be used for BOTH dirlist and the autoruns modules. -m dirlist -NC

By default, the dirlist module has been multithreaded to increase processing speed. Multithreading can be disabled with the -NM flag. -m dirlist -NM
