pymdm 0.4.2

Cross-platform utility package for MDM deployment scripts (Jamf Pro, Intune).

pymdm

A Python utility package for macOS MDM deployment scripts, built for MacAdmins Python (#!/usr/local/bin/managed_python3) and Jamf Pro workflows. Windows/Intune support is also available for teams managing mixed-platform fleets.

Features

• ParamParser: Safe parsing of Jamf Pro script parameters 4-11 (macOS)
• Dialog: swiftDialog integration for user-facing dialogs and notifications (macOS)
• CommandRunner: Secure subprocess execution with credential sanitization and platform-aware run-as-user
• SystemInfo: System information helpers — serial number, console user, hostname
• MdmLogger: Structured logging with file output, rotation, and multiple log levels
• WebhookSender: Send logs and metadata to webhooks
• IntuneParamProvider: Env var and argv parameter parsing for Intune scripts (Windows)

Installation

From Source

uv pip install -e .

Development

make install     # Install with dev dependencies
make test        # Run tests
make format      # Format code with ruff

Quick Start

Logging

from pymdm import MdmLogger

logger = MdmLogger(
    debug=True,
    output_path="/var/log/my_script.log"
)

logger.info("Script started")
logger.debug("Detailed information")
logger.warn("Warning message")
logger.error("Error occurred", exit_code=1)

Jamf Parameters (macOS)

from pymdm import ParamParser

# Get string parameter
webhook_url = ParamParser.get(4)  # $4 in Jamf policy

# Get boolean parameter
debug_mode = ParamParser.get_bool(5)  # "true", "1", "yes" -> True

# Get integer parameter
timeout = ParamParser.get_int(6, default=30)

Intune Parameters (Windows)

from pymdm.mdm import IntuneParamProvider

provider = IntuneParamProvider()

# Get from sys.argv
value = provider.get(1)

# Get from environment variable
webhook_url = provider.get("WEBHOOK_URL")

# Boolean from env var
debug = provider.get_bool("DEBUG_MODE")

Auto-Detect MDM Provider

from pymdm.mdm import get_provider

# Automatically selects Jamf on macOS, Intune on Windows
# Override with PYMDM_MDM_PROVIDER env var
provider = get_provider()

value = provider.get(4)  # Jamf: sys.argv[4], Intune: sys.argv[4]
debug = provider.get_bool("DEBUG")  # Intune: env var lookup

Command Execution

from pymdm import CommandRunner

runner = CommandRunner(logger=logger)

# Safe execution (list form)
output = runner.run(["/usr/bin/id", "-u", username])

# Shell execution (for pipes, etc.)
output = runner.run("ps aux | grep python", timeout=10)

# Run as logged-in user (platform-aware)
# macOS: uses launchctl asuser
# Windows: uses PowerShell Start-Process
runner = CommandRunner(logger=logger, username="jsmith", uid=501)
output = runner.run_as_user(["/usr/bin/open", "-a", "Safari"])

System Information

from pymdm import SystemInfo

# Get serial number
# macOS: system_profiler | Windows: PowerShell/wmic
serial = SystemInfo.get_serial_number()

# Get console user info
user_info = SystemInfo.get_console_user()
if user_info:
    username, uid, home_path = user_info

# Get hostname
hostname = SystemInfo.get_hostname()

# Get full name
full_name = SystemInfo.get_user_full_name("jsmith")

Webhook Integration

from pymdm import WebhookSender, MdmLogger

logger = MdmLogger(output_path="/var/log/script.log")
webhook = WebhookSender(
    url="https://hooks.tray.io/...",
    logger=logger
)

# Send log with metadata
webhook.send(
    hostname=SystemInfo.get_hostname(),
    serial=SystemInfo.get_serial_number(),
    script_name="my_deployment_script",
    status="success"
)

Complete Example (macOS / Jamf Pro)

#!/usr/local/bin/managed_python3
"""Example Jamf Pro policy script."""

from pymdm import (
    MdmLogger,
    ParamParser,
    CommandRunner,
    SystemInfo,
    WebhookSender,

# Setup
logger = MdmLogger(
    debug=ParamParser.get_bool(4),
    output_path="/var/log/my_script.log"

try:
    # Get system info
    serial = SystemInfo.get_serial_number()
    hostname = SystemInfo.get_hostname()

    logger.info(f"Running on {hostname} ({serial})")

    # Execute command
    output = runner.run(["/usr/bin/sw_vers", "-productVersion"])
    logger.info(f"macOS version: {output}")

    # Send results
    webhook = WebhookSender(
        url=ParamParser.get(5),
        logger=logger
    )

        hostname=hostname,
        serial=serial,
        status="success"
    )

except Exception as e:
    logger.log_exception("Script failed", e, exit_code=1)

Complete Example (Windows / Intune)

"""Example Intune deployment script."""

from pymdm import MdmLogger, CommandRunner, SystemInfo, WebhookSender
from pymdm.mdm import IntuneParamProvider

# Setup
params = IntuneParamProvider()
logger = MdmLogger(
    debug=params.get_bool("DEBUG"),

Platform Configuration

Environment Variables

Variable	Purpose	Values
PYMDM_PLATFORM	Override platform auto-detection	darwin, win32
PYMDM_MDM_PROVIDER	Override MDM provider auto-detection	jamf, intune

Task Mapping: Jamf vs Intune

Jamf Pro	Intune Equivalent	pymdm API
ParamParser.get(4)	IntuneParamProvider().get("PARAM_NAME")	get_provider().get(...)
ParamParser.get_bool(5)	IntuneParamProvider().get_bool("FLAG")	get_provider().get_bool(...)
Script params via sys.argv[4-11]	Env vars or sys.argv	Provider-specific
jamf recon	Microsoft Graph API	Not in pymdm (use provider SDK)
swiftDialog	Windows toast/WPF	Dialog (macOS only)

Migration Notes

From pymdm < 0.4.0

All existing imports and APIs are fully backward compatible. No changes required for macOS/Jamf scripts:

# These all work exactly as before
from pymdm import SystemInfo, CommandRunner, ParamParser, MdmLogger

For new Windows/Intune scripts, use the new provider APIs:

from pymdm.mdm import IntuneParamProvider, get_provider
from pymdm.platforms import get_platform
