Keeping Jamf Security Cloud Sharp for O365
When I first wrote about troubleshooting Standard Routing Policies in Jamf Security Cloud, the goal was simple: help admins keep Microsoft Teams and Microsoft 365 traffic flowing smoothly through Jamf Trust + App-Based VPN.
Fast-forward, Microsoft has added additional IP ranges and hostnames — and if you’re relying solely on Jamf’s built-in policy, you’re eventually going to feel the pain when Teams, Outlook, or SharePoint suddenly stop behaving.
This post updates the original allow-list to ensure full functionality with Microsoft 365 services, including Teams calling, media, authentication, and content delivery.
As before — we don’t remove anything. We only add what’s required and label what’s New.

What Changed?
Microsoft is rapidly expanding delivery and authentication networks to support:
- Teams AV media & recording services
- CDN-accelerated Office 365 content
- Exchange and Outlook authentication shifts
- Azure AD / Entra traffic delivery upgrades
- Regional cloud & edge expansion
Jamf’s default routing list still doesn’t always catch everything — so the safest path is periodic manual validation against the Microsoft service endpoint list.

Conclusion
Once again — the minute these new entries were added, end-user friction disappeared. Teams behaved, Outlook synced, and Microsoft 365 returned to the smooth experience we expect.
Key takeaway:
Even with platform vendors automating routing intelligence, cloud environments evolve faster than policy libraries. Review, validate, test, and stay ahead — or your users will alert you the hard way.

Automating JAMF Pro Email Notifications with SendGrid (Smart Group Driven Workflows)
Modern device management isn't just about enforcing policies—it's about communicating effectively with users at the right time. In JAMF Pro, Smart Groups give you powerful visibility into device state, but they don't natively solve the problem of proactive, automated user communication. Whether you're trying to prompt users to restart their machines, complete updates, or take action on compliance issues, bridging that gap requires a flexible and scalable notification system.
The Day I Unmanaged a Mac Into a Corner
There are a few kinds of mistakes you make as a Mac admin. There are the ones that cost you time, the ones that cost you sleep, and then there are the ones that leave you staring at a perfectly good laptop thinking, “How did I possibly make this *less* manageable by touching it?” These mistakes often stem from a lack of understanding or experience with macOS, but they can also be the result of rushing through tasks or not taking the time to properly plan and test.
Updating Safari on macOS with Jamf Pro: Three Practical Strategies
Keeping Safari updated is one of the simplest ways to harden a macOS fleet. Apple ships security fixes for Safari frequently, and those patches often land before a full macOS point release. This means that by keeping Safari up-to-date, you can ensure your users have access to the latest security protections without having to wait for a major operating system update. If Safari is lagging behind, your users are browsing the web with a larger attack surface than necessary.
Hunting Down Jamf Profile Payloads with Python
If you've spent enough time living inside Jamf Pro, you eventually run into the same problem: someone set a configuration somewhere, sometime, and nobody remembers where. It might be something obscure – a certificate payload, a conditional SSO predicate, or that one security preference quietly misbehaving on three machines in accounting. And when you have dozens of configuration profiles, each with multiple payloads, nested keys, and XML-wrapped values, finding that setting can feel like forensic archaeology.
Cleaning House in Jamf Pro: A Friendly Auditor Script for Real-World Hygiene
There’s a tipping point in every Jamf Pro environment where the policy list begins to feel like a junk drawer. Everyone means well. Nobody deletes anything. And then, months later, you’re trying to answer simple questions like: *Which policies are actually scoped? What’s no longer referenced? Why are there five versions of the same script?* This post covers a small, practical script I wrote to help you **see** what’s stale, **explain** why it’s stale, and (optionally) **park** it safely out of the way—without deleting a thing.
Turn Jamf Compliance Output into Real Audit Evidence
Most teams use Apple’s macOS Security Compliance Project (mSCP) baselines because they scale and they’re repeatable. Jamf’s tooling makes deployment straightforward and the Extension Attribute (EA) output is a convenient place to capture drift. What you don’t automatically get is the artifact an auditor will accept on a specific date—an actual document you can file that shows which endpoints are failing which items, plus a concise roll-up of failure counts you can act on. Smart Groups answer scope; they don’t produce evidence.
The Power of Scripting App Updates Without Deploying Packages
Keeping macOS environments up-to-date in a seamless, efficient, and low-maintenance way has always been a challenge for IT admins. Traditional package deployment workflows can be time-consuming, prone to versioning issues, and require extensive testing and repackaging. This can lead to frustration and wasted resources as IT teams struggle to keep pace with the latest updates and patches. But there's another way—a more elegant, nimble approach: scripting.
Detecting Invalid Characters and Long Paths in OneDrive on macOS
Microsoft OneDrive is widely used for syncing documents across devices, but on macOS, it can silently fail to sync certain files if they violate Windows filesystem rules — like overly long paths or invalid characters. This creates frustrating experiences for end users who don’t know why files aren’t syncing.
Using a script to Enable FileVault via JAMF: A Word of Caution
Enabling FileVault is a critical step in securing macOS devices, particularly in managed environments like schools, enterprises, and remote teams. For administrators using **Jamf Pro**, automating this process can simplify device onboarding and ensure compliance with disk encryption policies. This automation also helps reduce the administrative burden associated with manually configuring each device, allowing IT staff to focus on other tasks while maintaining a secure environment.
