Determining Adobe Creative Cloud sign-in status on a Mac

Adobe Creative Cloud app can get in weird state that blocks users from seeing their apps.

The official solution from Adobe is to delete the file /Library/Application Support/Adobe/OOBE/Configs/ServiceConfig.xml and “restart” Adobe CC, however in the real world you need to sign out and sign back in for the fix to take effect. The folks in the Adobe forums also found that you can change the value of the AppsPanel key from false to true and that does the trick too. Either way it still requires the user to sign-out of Adobe CC and back in.

Now, if you are a MacAdmin with a script that either deletes or modifies ServiceConfig.xml, you will ideally tell the user to Sign Out of Creative Cloud for the fix to take effect. Wouldn’t it be nice to be able to check they’ve done so and prompt them appropriately (or not)? For sure, right!?

There’s a per-user file with ideal behavior, that gets created upon sign-in and removed upon sign out: ~/Library/Application Support/Adobe/Creative Cloud\ Libraries/LIBS/librarylookupfile While its presence shouldn’t be taken as absolute proof that the sign-In is valid, it can be helpful when you need to alert the user what their next steps are. Here’s a simple example that just echoes out the status:

#consoleHasAdobeCCSignIn - Copyright (c) 2022 Joel Bruner - MIT License

function consoleHasAdobeCCSignIn()(
	consoleUser=$(stat -f %Su /dev/console)

	#if root grab the last console user
	if [ "${consoleUser}" = "root" ]; then
		consoleUser=$(/usr/bin/last -1 -t console | awk '{print $1}')
	sudo -u ${consoleUser} sh -c 'ls ~/Library/Application\ Support/Adobe/Creative\ Cloud\ Libraries/LIBS/librarylookupfile &>/dev/null'
	return $?

if consoleHasAdobeCCSignIn; then
	result="Signed In"
	result="Signed Out"

echo "Adobe CC status ($(stat -f %Su /dev/console)): $result"
Example output

In a fully fleshed out script you could use my shell function shui to pop-up a sharp looking AppleScript alert to your user if they need to sign out or just sign in. You can even use the icon in your pop-up.

You could also use the consoleHasAdobeCCSignIn function in a Jamf Extension Attribute for tracking which Macs have actually signed into Adobe CC and possibly reclaim unused licenses. I’ll leave the uses and script cobbling to you the reader, as an exercise. Thanks for reading!

brunerd tools summer 2022 updates

Hey there, it’s summer 2022 and I wanted to share some updates on my shell tools for Mac admins.

No breaking changes or anything huge, but some nice incremental improvements all the same. When the JSONPath spec is finalized I’ll give jpt a more considerable under the hood improvement. For now though, I’m pretty happy with tweaking their behaviors to act like you’d expect (print help and exit if no input detected), to get out of your way when you need to debug your scripts (xtrace is now disabled inside them) and to try to understand what you mean when you ask them a question (key path queries now accepted). Because the tools and technologies we make should serve us, not the other way around. I hope these tools can save you time, energy, sanity or all the above!

β€’ jpt the “JSON Power Tool” has been updated to v1.0.2 with all the nice additions mentioned. If you don’t know already jpt can parse, query, and modify JSON every which way. It can be used as both a standalone utility as well as a function to be embedded into your shell scripts, without any other dependencies.

β€’ ljt the “little JSON tool” is jpt‘s smaller sibling weighing in at only 2k. While it lacks the transformational powers of jpt it can easily pluck a value out of JSON up to 2GB big and output results up to 720MB. It has been updated to v1.0.7 because dang it, even a small script can have just as many bugs as the big ones. Sometimes more if you’re not careful!

Both jpt and ljt now accept ye olde NextStep “keypath” expressions to help win over masochists who might still use plutil to work with JSON! 😁 (I kid, I kid!)

β€’ jse, the “JSON string encoder” does this one thing and does it well. It can be used in conjunction with jpt when taking in arbitrary data that needs encoding only. It’s a svelte 1.4k (in minified form) and runs considerably faster that jpt, so it’s ideal for multiple invocations, such as when preparing input data for a JSON Patch document. v1.0.2 is available here

β€’ shui lets you interact with your users with AppleScript but in the comfort of familiar shell syntax! You don’t need to know a line of AppleScript, although it does have the option to output it if you want to learn. Save time, brain cells and hair with shui, while you keep on trucking in shell script. It has been updated to v20220704.

P.S. All these tools still work in the macOS Ventura beta πŸ˜…

New Projects: jpt and shui, Now Available

Between March and October 2020 I had some great ideas for command line Mac utilities the MacAdmin could apprecite and I had the time to devote to their realization. I’m excited to present these two open source projects, available on GitHub: jpt and shui. I hope they can add richness to your shell scripts’ presentation and capabilities without requiring additional external dependancies.

jpt – the “JSON Power Tool” is a Javascript and shell script polyglot that leverages jsc, the JavascriptCore binary that is standard on every Mac since 10.4 and since the jpt is purposefully written in ES5 to maintain maximum compatibility, why yes, this tool does run on both PPC and Intel Macs all the way back to OS X Tiger and then all the way forward to the latest 11.0 macOS Big Sur! Many Linux distros like CentOS and Ubuntu come with jsc pre-installed also, even Windows with the Linux Subsystem installed can run jsc and therefore can run the jpt!

What you can do with the jpt? Query JSON documents using either the simple yet expressive JSONPath syntax or the singular and precise JSON Pointer (RFC6901) syntax. The output mode is JSON but additional creative output modes can render JSONPaths, JSON Pointer paths, or even just the property names with their “constructor” types (try -KC with -J or -R) Textual output can be encoded in a variety of formats (hex/octal/URI encoding, Unicode code points, etc…), data can be modified using both JSON Patch (RFC6902) operations (add, replace, remove, copy, move, test) and also JSON Merge Patch (RFC7386) operations. JSON can be worked with in new ways, try -L for “JSONPath Object Literal” output to see what I mean. Or you simply feed jsc a file to pretty-print (stringify) to /dev/stdout. I’ll be writing more about this one for sure.

shui – first-class Applescript dialog boxes in your shell scripts without needing to remember esoteric Applescript phrasings! If you think it’s odd for code to have possessive nouns and are more comfortable in shell, you’re not alone. shui can be embedded in either bash or zsh scripts but it can also output Applescript if you really want to know how the sausage is made or want to embed in your script without shui. Hopefully shui will let you forget those awkward Applescript phrasing and focus on your shell script’s features and functionality. It uses osascript to execute the Applescript and launchctl to invoke osascript in the correct user context so user keyboard layouts are respected (vs. root runs). Check out the project page for demo videos and then give shui a try.
