diskspace Tool to Report APFS Free Space

Armin Briegel:

With the recent versions of macOS, getting a value of the available disk space is not as strightforward as it used to be. There are a lot of files and data on the system, which will be cleared out when some process requires more disk space. Most of this is cache data or data that can be restored from cloud storage. But this ‘flexible’ available disk space will not be reported by the traditional tools, such as df or diskutil. The available disk space these tools report will be woefully low.

The available disk space which Finder reports will usually be much higher. There is functionality in the macOS system frameworks where apps can get the values for available that takes the ‘flexible’ files into account.


I built a command line tool that reports the different levels of ‘available’ disk space. When you run diskspace it will list them all. There are raw and ‘human-readable’ formats.

It’s open source and available here.


ThinkTank Review From 1983

Dave Winer:

[Way] back in 1983, Infoworld reviewed ThinkTank, my first outliner.

This review, along with the one in the NYT, launched the company. Early the next year we shipped our Macintosh product at the Mac rollout in Flint Center.

John Gruber:

This review is amazing. But what the heck were they talking about with “the Pascal operating system”?

Dave Winer:

It was the UCSD P-system. Without it I would not have wanted to make Apple II software, nor would I have been able to build an app as rich as ThinkTank. UCSD was an orders of magnitude more memory-efficient than BASIC or assembly language. And it had overlays. Which meant if something didn’t have to be in memory all the time, it could be swapped in when needed. Most Apple IIs only had floppy drives in those days, so it was slow and a pain in the ass, but a lot faster than quitting the program, inserting another disk and launching another app just to edit the text of a headline. What I learned as a result of Gruber’s inquiry is that the P-system was one James Gosling’s inspirations for Java.

High Power Mode for Mac


Your MacBook Pro has multiple energy modes you can switch between. By default, your Mac is set to Automatic mode to balance energy use and performance. Low Power Mode reduces energy use to increase battery life. On the 16-inch MacBook Pro with M1 Max, High Power Mode allows the fans to run at higher speeds. The additional cooling capacity may allow the system to deliver higher performance in very intensive workloads.

You can use High Power Mode to improve performance in graphics-intensive workflows such as color grading 8K ProRes 4444 and 8K DNxHR video. In video editing and 3D applications, you may experience smoother playback and faster exports when High Power Mode is on.


High Power Mode can be used whether your Mac is connected to power or not.


Netflix Games for iOS

Ash Parrish:

Users will be able to choose from one of five games: Stranger Things: 1984, Stranger Things 3: The Game, Shooting Hoops, Card Blast, and Teeter Up. Starting today, users can download Netflix games from the Google Play store, requiring a Netflix subscription to play. Then on November 3rd, Netflix will begin rolling out games to the app itself. When on a mobile device, Netflix Games will come packaged in its own dedicated row and have a dedicated tab.

Steve Troughton-Smith:

It sounds like these will be individual games on the App Store, but accessed through your Netflix subscription. Abiding by the rules Apple came up with on the spot to push Microsoft’s Xcloud away from iOS

Jason Snell:

If Netflix wants to be on iOS, it will almost certainly submit every game to the App Store on its own, and then you’ll connect them to your Netflix subscription in order to play them. (I imagine the Netflix app itself will gain links to those apps, but that the apps themselves will be delievered via the App Store.)

That all would seem to be within the letter of the App Store guidelines, but of course, there’s nothing stopping Apple (except publicity and regulatory scrutiny!) from amending its rules or its interpretation of those rules in order to make things harder for Netflix.
