The amount of free space required to upgrade a Mac has increased drastically in the run-up to and since the introduction of apfs-based snapshots in 2016. The amount of required free space had been growing steadily in the HFS+-era of file systems, but as more elements of iOS (like a modern file system) came to the Mac, and as the Mac transitioned to a fully 64-bit operating system, that number escalated and never returned now that the transition away from things like 32-bit apps and kexts is finished. Sierra (Mac OS X 10.12) had a minimum drive capacity of 8.8 GB but really needed more like 12 GB; however there…

Notes from the Underground: Apple WWDC and You
Apple kicked off the annual WWDC conference yesterday and boy there was a flurry of information. There always is, but for people charged with managing Apple devices and vendors that support Apple devices there were some important releases. Some general themes to think about as you read through this list: Privacy is a thing. This includes securing files in the directories of a user by having the user accept a request to touch them (e.g. My Documents, er, I mean, Documents). This also means apps harvesting user data are doomed. The restrictions continue to flow in from iOS to the Mac. And that’s probably a good thing – as it…

Transfer Text In And Out Of The iOS Simulator Using xcrun
In a previous article, I covered creating, starting, and stopping iOS simulations. macOS comes with a handy tool to interact with the clipboard (aka pasteboard) on a Mac called pbcopy. You can redirect information from a file into your clipboard using the pbcopy command. Here, we’ll simply call pbcopy and then a file path pbcopy ~/Desktop/transfer.txt You can then redirect your text into simctl by doing a pbpaste into xcrun simctl pbpaste booted Once you’ve copied your data, clean up the transfer file: rm ~/Desktop/transfer.txt You can also pull text out. If you write data into the clipboard (e.g. during instrumentation) then you can extract it from that pasteboard using…

Screen Time And Setting Limits For Ourselves And Our Families
Do you know how much time you spend in various apps and on your device?

Using Managed App Config with Jamf Pro
Hey look, there’s a new category on the Jamf Marketplace, available at https://marketplace.jamf.com/apps/#category=AppConfig,selecting the AppConfig category. The new AppConfig category gives administrators of any MDM that supports AppConfig access to a set of apps that support AppConfig. If you have an app that isn’t listed here, feel free to let me know. What does this mean? Well, AppConfig is a way of sending data into an app. App config allows a customer to deploy settings into applications on iOS devices in much the same way that settings can be sent into a Mac app via the defaults command. This means an end user could get an app installed on their device…

Ways to work together with your employees to help keep their skills sharp
My latest inc.com piece is available at https://www.inc.com/charles-edge/your-employees-want-extra-training-but-youre-going-to-have-to-help-them-get-star.html. It starts off like this, if it’s your kinda’ thing: Employee engagement is dipping, according to a new study by human resources consultancy Aon Hewitt, but as an manager, you can make the workplace more appealing through positive initiatives such as employee training and development. Indeed, I’ve often had people I manage ask for more training. My answer is always an emphatic “yes.” But then something funny often happens: nothing. Giving staff approval for trainingdoesn’t necessarily mean that they’ll do it unless you follow up methodically and even micromanage the process. Why does this happen and what does it show about how employers…

Use DNS To Improve Caching Service Discoverability
Clients discover the Apple Caching service bundled with macOS Server (and in the future macOS) automatically. You can create a text recored for _aaplcache._tcp on your DNS server. That would look _aaplcache._tcp 518400 IN TXT “prs=192.168.50.100” Name: _aaplcache._tcp with a type of TXT and a TTL of 518400 seconds. The prs is the address to be used and is set to a value using prs=192.168.50.100.
