On macOS, you can access and read which managed preference settings are currently being applied to a particular Mac.

Every so often when working with the unified logging system, you need to know how far back the current logging goes.

Earlier this year, I had written a post about a problem I observed with manually copied login keychains not working when moved to another Mac.

One of the less documented changes to macOS Golden Gate is the removal of Apple Filing Protocol (AFP) as a supported network protocol.

One of the new management options available for Apple devices running OS 27 is the App Settings declaration.

As part of testing macOS Golden Gate, it was discovered by myself and others that MDM enrollment does not appear to completely work.

As part of Apple’s ongoing transition from Intel processor support, Apple announced a transition timeline for macOS’s Rosetta 2 translation environment in 2026.

Over the years, Apple has introduced a number of screens which appear the first time you log into a Mac.

I recently encountered an issue with the login keychain on macOS.

I recently needed to determine whether communication between an MDM server and a managed Mac was working, entirely from the Mac’s side.

A while back, I wrote a script which uses Jamf Pro’s Classic and Jamf Pro API to retrieve FileVault recovery keys.

As part of reporting on Jamf Pro API clients and assigned API roles, I had previously written a script to report on the following information: The current list of the enabled and disabled API clients on a Jamf Pro server.

As part of a recent discussion in the Mac Admins Slack, it was asked if it was possible to validate a FileVault personal recovery key (PRK) without having to interactively enter it.

To follow up on my earlier post about creating API roles with all available privileges, I’ve developed a script which will create API Roles with API privileges that are roughly equivalent to the API privileges for Jamf Pro accounts which have been assigned

I’ve been doing some work with API clients on Jamf Pro, which use API Roles to assign API privileges to the API client.

As part of an earlier project, I had set up a status board using MagicMirror on Ubuntu LTS.

The good folks at Penn State have posted the session videos from Penn State MacAdmins Conference 2026.

I recently gave a talk on how FileVault works on Apple Silicon Macs running macOS Tahoe.
