Update season has started. After the event on Tuesday, where Apple announced new Watches and iPads, iOS 14 shipped on Wednesday, giving developers and admins less than 24 hours advance warning and probably the shortest lived GM ever.

We also got macOS Big Sur beta 7 and new betas for iOS 14.2 and siblings.

The future releases of hardware and software this year shou

If you need something to distract from the wait, I can recommend the MacDevOps YVR videos.

macOS Version Big Sur Update
Versioning software is a surprisingly difficult task. The version number conveys technical information: how much change can you expect and might it break existing workflows and data? Users will be more willing to pay for a major upgrade with new features, so the version number is used as a marketing tool. But for developers and MacAdmins, the version number has to be as granular as possible, idea

How can it be September already!? Where did the summer go?

Apple’s beta phase is heating up with a new beta release for iOS and macOS. We also got iOS and iPadOS 13.7.

Since Fall is here, so are some more virtual conferences. I will have sessions prepared for Virtual JNUC and MacSysAdmin Online.

Virtual JNUC 2020 is happening September 29 through October 1. You ca

Some great posts from fellow MacAdmins this week. New betas for iOS 14 and iOS 13.7(!) dropped, but none for macOS so far.

Remember that you can still register for Virtual JNUC 2020 for free. you won't just get to see my great talk, but there are many other amazing talks from amazing MacAdmins.

Running a Command as another User
This post is an update to an older post on the same topic. macOS has changed and I had a few things to add. Rather than keep modifying the older post, I decided to make this new one.

As MacAdmins, most of the scripts we write will use tools that require administrator or super user/root privileges. The good news here that many of the management tools we can use to run scripts on clients

Welcome back! I get the impression I was the only one to take a while off this summer. So many post to sort through and link to…

I will be presenting at Virtual JNUC2020 this year. My session is “Scripting Jamf: Best Practices” (JNUC307) and is scheduled for Oct 1 at 11am CT (18:00 Central European time). The entire session schedule can be reviewed on their site and

You can’t really tell it from the weather here in the Netherlands, but summer is here!

Summer brings more beta testing: the third beta of the new Apple systems dropped this week. It also brings vacation. This newsletter will be on vacation until late August. As usual, I will keep gathering interesting posts and links and return with a big August summary.

Hope you g

Installomator Updated: v0.3
It’s been more than a month since the last update, and while there has been work on the dev branch, I was quite distracted with other things (like this). The good news is, that there have been quite a few contributions from others! A huge thanks to all who helped make this a better script.

All it took was for me to find some time to put all the contributions together, which I finally found some tim

No summer break yet for MacAdmins. As expected, the updates for macOS Catalina 10.15.6 and iOS 13.6 and siblings were published.

As a big reprieve for MacAdmins, the functionality of softwareupdate --ignore has been re-instated for system software updates, but only when the Mac is supervised (i.e. enrolled in MDM with Automated Deployment or user-approved MDM). This

This week brought more reactions to WWDC news regarding macOS 11 Big Sur, iOS 14, and the Apple Silicon transition. Apple released beta 2 for all the above (excluding the DTK), which were later released as the first public beta. We also got GM betas for macOS Catalina 10.15.6 and iOS 13.6. And a new ransomware named EvilQuest, later changed to ThiefQuest.

Busy week.

The week after WWDC: time for opinion and reaction pieces. And time to dig into the betas and find the first bugs and annoying changes.

But Apple hasn’t forgotten the Catalina/iOS 13 updates either. We got new betas for 10.15.6 and iOS 13.6.

macOS 11
Last week at WWDC, Apple had two big announcements for the Mac platform.

The first one was a new user interface design, much closer to iPadOS and iOS. Apple considers this the “biggest design upgrade since the introduction of Mac OS X.” Because of this, Apple also gives this version of macOS the long-withheld ‘11’ as the major version number.

You can take a look at the new UI on Apple’s Big Sur preview page or you can download the be

Phew, it’s really summer here in NL, hot and humid. And it’s been a ‘hot’ week for many other reasons, too.

This news summary took a while and is a bit later than usual… you will see why…

If I missed anything, let me know and I will catch up next week.

About bash, zsh, sh, and dash in macOS Catalina and beyond
This is an excerpt from my book: “Moving to zsh.” At the MacAdmins Conference Campfire session I received quite a few questions regarding this, so I thought it would be helpful information. You can get a lot more detailed information on “Moving to zsh” in the book!

Calls to the POSIX sh /bin/sh in macOS are handled by /bin/bash in sh compa

WWDC is looming! We got a bit more detail on the schedule for the first day (June 22). over the following week, Apple will release recorded sessions each day at 10am Pacific Time. Talk about an ‘info dump!’ There will also be ‘1–1 Developer labs’ which you can sign up for and new Developer forums (fora?) which go online June 18.

The rumors are running hot with Mark

Installomator updated: v0.2
It’s been nearly a month since I introduced Installomator.

Since then, it has gotten lots of feedback from others and many contributions. As the changes, fixes and additional apps have accumulated, I have created a 0.2 release to get a stable new version. If you like living on the edge you can also use the dev branch for the latest update.

Changes in this version:

“So, do you think one day robots will have human rights?”

“Perhaps,” the robot said, “but first I want to see all humans have human rights.”

“What do you mean? All humans do have human rights. It’s in the name.”

“Then I first want to see all humans considered human.”

“Oh. Yeah.”

Using Installomator with Jamf Pro
I introduced the Installomator script a while back. We have been using the script with our own Jamf Pro server and some of our customers.

Since I built the script, you’d think I’d have pretty good idea on how it should be deployed. But then Mischa van der Bent showed me a better way of using Installomater with Jamf Pro and I asked him to write it up for a blog post. Since he doesn’t ha
