MacSysAdmin 2017 Conference Open for Registration

You can now register for the MacSysAdmin Conference in Göteborg (Sweden) which will go from October 3-6.

It is a great conference and I have wanted to go for years, but never managed to make it. The list of speaker has been and is really very impressive.

So I am very proud to announce that not only will I be attending but also presenting a session on macOS bash scripting this year! (so literally a session on ‘Scripting OS X… macOS’)

Looking forward to seeing you all there!

Mac Pro: Signs of Life

This week’s big surprise is that Apple has let out some early news that they are working on a new Mac Pro. Even more interesting than new hardware is (for me) that Apple is trying to re-assure the pro and prosumer market that Apple cares about them.

Micheal Tsai has a great summary post.

On Viewing `man` Pages

When you frequently use Terminal, you will use man pages. They contain tons of useful information on most of the tools and commands you use on the shell.

However, the man command’s user interface was designed for terminal output decades ago and does not really integrate well with the modern macOS UI. When you run the man command the output will take over your current Terminal window and scrolling through long man pages can be tedious.

Normal man page in Terminal


However, on macOS you do not have to man like it’s 1989.

First solution is to use

$ open x-man-page://ls

instead of man. This will open the man page in a new yellow Terminal window, so you can still see what you are actually doing, while reading the man page. If the yellow is just too annoying for you, you can change the look of the window by changing the ‘Man Page’ window profile in the Terminal Preferences. Since this window shows the entire man page, you can scroll and even use ‘Find’ (Command-F) in this window.

The beautiful yellow x-man-page window

Since typing this open command is a bit awkward, you can add a function to your bash profile or bashrc file:

function xmanpage() { open x-man-page://$@ ; }

Note: You could use xman here. However, that will conflict with another command when you have X11/XQuartz installed.

You can also put ‘x-man-page:’ URLs in other applications, such as emails or chat applications. However, not all applications will recognize URLs starting with x-man-page: as URLs, so your results may be mixed. It does work in Slack, even though Slack is skeptic of the links:

Slack will warn you about unusual links

Taken from Context

In Terminal, you can open a man page from the context menu. Simply do a secondary (ctrl/right/two-finger) click on a word in a Terminal window and choose ‘Open man Page’ from the context menu. This will open the man page in a separate window, like opening x-man-page URLs.

Open man Page in the Terminal context menu

man Page with a (Pre)view

Back in the early days of computing you could (or had to) convert man pages into postscript output, so they would look nicer when printing. These options are still present and we can (ab)use them to show a man page in Preview. (Please don’t waste paper printing man pages.) The command for this is:

$ man -t ls | open -f -a "Preview"
Preview showing a man page

The -t options pipes the man page into another tool (groff) to reformat it into pdf which we then pipe into open and send to the Preview application. (More on the open command.) If you use this more frequently, you want to create a function for this in your bash profile or .bashrc:

function preman() { man -t "$@" | open -f -a "Preview" ;}

Text Editors

You can also send a man page to a tex editor. Before you pipe the output into a text editor, you have to clean it up a bit:

$ MANWIDTH=80 MANPAGER='col -bx' man $@ | open -f

This will open in TextEdit. If your favored text editor can receive data from stdin, then replace the open -f with its command. For BBEdit, this will work great:

$ MANWIDTH=80 MANPAGER='col -bx' man $@ | bbedit --clean --view-top -t "man $@"

And again, if want to use this method frequently, create a bash function for it.


The ManOpen application has been around for a long, long time, but amazingly, it still works on macOS Sierra. It will also display man pages in a separate window. The main advantage MacOpen has over the other solutions here is that it will automatically detect other commands and highlight them as hyperlinks to their man pages. There is also a command line tool, confusingly called openman to open the app directly from the Terminal.


You can also create an Automator Service for this. Then you can open man pages from (nearly) any application with a keystroke or from the context menu. I described this in an older post on man pages.

Upgrade to the latest macOS that is compatible with your Mac.2
Requires macOS Sierra 10.12.4 or later. Reinstall the macOS that came with your Mac, or the version closest to it that is still available.

News Summary: Week of 2017-03-24

Back when I was a Server Sales Engineer I would make a weekly summary for other Field Engineers and customers on server and admin related news.

Thought I might try this tradition, again. Welcome to the first Scripting OS X Weekly News roundup!

On this Blog

I published my second book ‘Property Lists, Preferences and Profiles for Apple Adminstrators’! (PR3 for short) Get the details in the pre-sales announcement and download the book here!

I also posted an update to the Packaging book last week. It got a new cover to fit with PR3 and some internal changes and corrections. I also added an extra page with the version history for all the update details. If you have purchased the book already, iBooks should have notified you of the update. If you have been ignoring that red batch on the iBooks app, go check it out!

If you have the books and like them, please leave a review on iBooks store!

And then I continued with the articles on the Terminal and command line with a new post: [Terminal – the ’’ marks the spot.

If I missed anything, let me know in the comments, twitter or the MacAdmin Slack forum!

Apple acquires Workflow app

You’ve probable heard it already: Apple has bought the Workflow application. The developers will keep working at Apple and the Workflow app is now offered for free on the AppStore, although with a few interesting changes.

Workflow has always been one of those apps that would have liked to get into. However, as an admin, my workflows center on macOS and Unix. You cannot build packages on iOS. Even iBooks Author only exists on macOS. As much as I like the iPad and iOS it has been relegated to secondary device because of the focus of my work.

Still it will be interesting to see how Apple will integrate Workflow with iOS and the Apple applications. I am looking forward to it.

If you now want to catch up with what Workflow is all about, you can’t do much better than Frederico Viticci’s articles on MacStories.

Sierra update 10.12.4: Disable iCloud Desktop and Documents Sync

Babo D: Disable iCloud Desktop and Documents Sync

Very useful discovery. When you search Apple’s profile documentation page for ‘10.12.4’ you also find a new key to disable Touch ID login on the new MacBooks and an entire new payload type for SmartCard setup.

BTW: you can of course learn more about configuration profiles in my new book: ‘Property Lists, Preferences and Profiles for Apple Administrators’ available in the iBooks Store now!

New Book — Property Lists, Preferences and Profiles

As it happens so often, the plan changed.

The plan was to go from ‘Packaging’ right to the obvious sequel ‘Automated Packaging’. And I am working on that book. However, since AutoPkg uses property list files for the recipes, I needed to introduce property list file formats and all the tools, quirks and caveats.

So the sidenote on property lists grew into an appendix. And it kept growing. Then I thought it would be a waste to explain property list files but not talk about preference files. And once you explained preference files, you should also introduce configuration profiles, especially custom profiles. Profiles are property lists after all.

So I moved the chapter on property lists into a new iBook. And I added chapters on preferences and configuration profiles, leading to a cumbersome, but memorable title. (‘PR3’ for short.)

So, here we are, not a sequel, but a ‘sidequel’. I will of course continue writing ‘Automated Packaging’ once this book is published.

PR3 is not quite done yet. I am still getting great feedback from the proofreaders. (Thank you!) But all the small pieces that are still missing or need refinement should fall in to place next week and I aim to release on March 20. (Deep breaths!)

And there will be updates to the iBook (like with ‘Packaging’) as I find more typos and learn more in future.

As with ‘Packaging’ the main target audience is either an administrator who is new to the Mac platform or a Mac user who is new to Mac administration and management. However, the proofreaders have all told me, there are many nuggets and pieces of new information for experienced admins as well.

Until then you can download the first chapter on property list file formats from the iBooks Store!

You can also pre-order and get the book automatically, as as soon as I press the ‘Publish’ button!

Get it on iBooks

Overall, writing these books is a great experience. It is a great chance to dive deeply into a topic. It is also a great chance to give back to the community that is amazingly generous in sharing knowledge and experience. There are many more topics on my list that I would like to write books on.
