WWDC
We did get the "sleek peak" of the "26" versions of all the Apple platforms. They will have a new, very transparent interface style called "Liquid Glass."
After the Keynote and the Platforms State of the Union session on Monday, all sessions dropped at once, including the essential "What's new in Apple device management and identity", which every Apple Admin should watch.
There will be quite a few features and updates for management in the "26" platforms. You should check the 'What's new for IT" document in AppleSeed for IT for the details. There are already a few community posts about some of these. I expect more posts over the next few weeks, and a lot more when the upgrades are released later this year.
Tom Bridge reminds us all that developers, vendors and open source project maintainers learned about the new features and frameworks the same time as all of us. While it is important to start testing the new versions in your environment as soon as possible, and reporting issues to Apple and third-parties, it is also a good strategy to be patient and give third-party developers the time to adjust, plan, and react.
In other news, I will be participating and presenting at both European Jamf Nation Live events in Munich (June 24) and London (July 1). The Jamf team will be presenting many things that are new across the Jamf platforms. These are also great days to meet up with fellow admins and do some networking.
I will also be presenting at the Berlin Mac Admins Meetup on July 9. I'll be talking about MacAdmins Tools and how you can contribute to the community, even when you cannot write code. The presentation will be in English, but the Q&A and discussion afterwards will be bilingual. We thought that would be the most inclusive option.
Later in the year, I will be at MacSysAdmin in Göteborg. There are of course more conferences coming up, you can see a list on my conferences page.
Hope to see you there!

WWDC25 Recap and Thoughts
Tony Young on Patch Notes and Progress
Apple’s WWDC 2025 dropped some big changes—macOS Tahoe, a slick new design called Liquid Glass, and major updates for Mac admins and IT teams. Here’s what you need to know (and start testing) before fall hits.
Virtualising macOS 26 Tahoe
Rather than compromise and run Tahoe from a bootable external disk, which only reduces the risk, why not run it in a VM, where it should be safely isolated from the rest of your Mac?

Munki manifests are essentially XML, so you can write comments in the manifests to explain why you might have put something in (say, serial numbers in conditions). If you, however, edit and save a manifest using MunkiAdmin, MunkiAdmin doesn’t know about those comments

This falls on the "extremely prudent to the point of paranoia" side of the preparation scale, but if you wanted to archive a Rosetta installer...
With Rosetta 2 support winding down, time to revisit offline installer backups (Apple’s legacy software availability notwithstanding).
