Because of TCC/PPPC, which Apple introduced in macOS 10.14, scripts and applications have to ask for permissions to do certain things, especially things like reading user home directory files. If you have an Outset login script that tries to access something in the home directory, you may find in the ~/Library/Logs/outset.log that you get a… Continue reading Allowing Outset-run scripts to have access to user folders
If Jamf inventory (jamf recon) causes an extended CPU spike specifically related to the du command, you can fix that by going, in the Jamf settings, to Computer Management > Computer Management – Management Framework > Inventory Collection, and then uncheck the Include home directory sizes checkbox. That is a system-wide setting, but especially if… Continue reading If Jamf recon is launching a du process that causes a CPU spike
Starting with El Capitan (OS X 10.11), Apple started using System Integrity Protection (SIP) in macOS, so that certain directories would be not writable, even by root. Here’s a quick reference for a couple of commands you can use to see if a directory or file is SIP-protected, as that may change from macOS version… Continue reading Terminal command to tell if a macOS directory is SIP-protected
Background I was looking for time-based project similar to Outset (which runs boot and login scripts stored in various directories), and apparently there’s one already baked into macOS that will run daily, weekly, and monthly scripts. Shoutout to @elios on the MacAdmins Slack for letting me know about periodic Launch Daemons If you run sudo… Continue reading Running daily, weekly, and monthly scripts in macOS using periodic
Three years ago, Rich Trouton wrote Adding password protection to manually installed management profiles, which gives step-by-step instructions for how to make a manually-installed profile prompt for a custom password (in addition to the local admin password) when being removed. I’ve tested this on Catalina, and it still works! That said, it worked only from… Continue reading The limits of password-protecting a .mobileconfig profile
If you’ve deployed a PPPC/TCC profile from your user-approved MDM to a Mac, and you see the profile in System Preferences > Profiles, you can also verify all the details of the deployed profile on the Mac itself by going to /Library/Application Support/com.apple.TCC/MDMOverrides.plist (which is an SIP-protected directory, by the way).
Now that Apple has removed the –ignore flag from softwareupdate, it’s recommending you use the forceDelayedSoftwareUpdates and enforcedSoftwareUpdateDelay flags (more details in Device Management Profile: Restrictions), which are supposed to, in theory, delay an updates user visibility a certain number of days after the update’s release. The number of days delayed may not be precise… Continue reading Things to keep in mind if using a profile to delay macOS updates
If you’ve been doing Munki admin’ing for a short while, you’ve probably heard people talk about DEPNotify, whose README says is “a small light weight notification app that was designed to let your users know what’s going on during a DEP enrollment.” Aforementioned DEPNotify README is fairly comprehensive in terms of going over all the… Continue reading Some basics of DEPNotify and a sample script
If you haven’t changed any settings, and suddenly the Internet connection on your VMWare guest macOS installation goes out, and shutting down the VM or rebooting the VM doesn’t help, try rebooting the host Mac. That will likely fix the problem (not sure why that problem comes up in the first place.
Note about Silicon Macs This will not work with Apple Silicon Macs, as Apple now requires you to enter the password of a secure token user account in order to run startosinstall. Shoutout Shoutout to Rod Christiansen on the MacAdmins Slack for putting this strange (but still working for now) method of patching on my… Continue reading Using a full macOS installer with Munki to patch macOS
