Mac patch management: How to update macOS and apps

You’ve probably spent years getting Windows patching down to a science. Patch Tuesday has a familiar rhythm, your rings are tuned, and your reports give you visibility. But when the C-suite gets MacBooks, or the design team wants Mac Studios, you find yourself confronted with a platform that has no Patch Tuesday, no WSUS, and its own opinions about restarts.

The reality is that Macs aren’t really that hard to patch; the process is just different. Mac software updates find their way to user devices through multiple channels, and each one needs its own owner. In PDQ’s State of Sysadmin report, 51% of sysadmins already say timely security patching takes too much time. If you’re managing Macs in a Windows shop, the fix comes down to habits that you already have. You just need to apply them to the right layer.

What does Mac patch management include?

Mac patch management covers three types of updates, each with its own delivery channel:

• macOS updates: Point releases with security fixes. On Macs, Apple also ships non-OS updates for Safari, XProtect, printer drivers, and the Xcode command-line tools.

• macOS upgrades: Think of major releases like macOS 27 Golden Gate. They’re bigger and more likely to break things, so they need their own testing track before rollout.

• Application updates: Everything else, which is where your systems may be most exposed.

Apps diverge again based on how they arrived. App Store apps update through the App Store or through your MDM when you deploy them as managed apps with licenses from Apple Business.

Apps that are installed from a vendor PKG or DMG might update themselves through a framework like Sparkle or get updated by Homebrew, and some apps might not update at all until someone pushes a new installer.

You need to know which path each app uses for third-party application patching, and then pick one owner per app so that two systems aren’t fighting over the same version.

How do you build a reliable Mac patching workflow?

Reliable macOS patch management uses the same five stages that you already run on Windows.

1. Inventory: Record the macOS version and chip architecture, as well as installed app versions for every Mac. Flag any Intel Macs, because macOS 27 runs only on Apple silicon, so those machines are stuck on macOS 26 Tahoe or earlier.

2. Prioritize: Rank issues by exposure. Browsers and collaboration tools, or anything with an actively exploited vulnerability, usually go first.

3. Pilot: Test on Macs that already have some history, not just on clean installs. Older OS versions and developer machines are good test candidates.

4. Deploy in rings: Move from IT devices to pilot users, then on to the rest of the fleet. For macOS, Apple’s deferrals hold back updates on supervised Macs for 1–90 days, where there are separate timers for updates, upgrades, and non-OS updates.

5. Verify: Confirm the installed version, not just the deployment logs. Installers can report successful installations even when the new version didn’t completely install.

The Windows and macOS patching playbook goes into more detail about each stage. On Macs, two issues need extra planning.

User prompts and restarts: When apps are left open they can block updates from completing, so it’s a good idea to ask users to save their work and close the app for a few minutes. For enforced OS updates, Macs send notifications more often as the deadline looms closer, and those notifications ignore Do Not Disturb in the final 24 hours. 

When time runs out, macOS force quits open apps, unsaved documents included, and restarts if necessary. So warn users early, unless you enjoy helpdesk tickets about spreadsheets that vanished mid-edit.

Offline devices: Laptops travel, sleep, and occasionally miss maintenance windows. If a Mac misses an enforced OS update, it picks up where it left off once it reconnects. App deployments depend on the tool, so plan retries or a cleanup ring for stragglers. PDQ queues app deployments for offline devices and retries them when those devices come back online.

Where do MDM and endpoint patching tools fit?

An Apple MDM owns macOS update enforcement. With the OS 27 releases, Apple removed the legacy MDM software update commands, so deadlines, deferrals, and automatic install settings now run through declarative device management.

An endpoint management tool can own the app layer, especially software from outside the App Store. That’s where PDQ fits into the equation. The PDQ macOS agent provides real-time inventory, deploys prebuilt or custom Mac packages, patches vulnerable apps, and runs Bash or Zsh scripts from the same console you use for Windows. PDQ uses an agent instead of Apple’s MDM framework, so it complements your MDM and doesn’t replace it.

To find coverage gaps, give every update type a single owner:

Let MDM enforce macOS, give every app one owner, and verify versions. Want to patch Mac apps from the same console as your Windows fleet? Start a free trial.
