Let the great Homebrew migration begin. Yes, Homebrew now has native support for Apple’s ARM64-based M1 chip. The latest version, 3.0.0, released 5 February, will run nicely on your Apple Silicon Mac. There’s a catch, of course. Well, several catches: first, not all of the tools you can install using Homebrew are M1 native yet and, second, Homebrew doesn’t offer explicit migration instructions, that I could find at least.

A first look at a MicroPython marvel: the Raspberry Pi Pico, in partnership with a Mac
On Thursday morning I awoke to the news that the Raspberry Pi people have entered the microcontroller board market with a new product, the Raspberry Pi Pico. Before I’d even got out of bed, I ordered a couple. Well, at £3.60 a pop, why not? I’ve now had a chance for a quick play, and here are my findings.
Continue readingOi, app makers, no! Enough Markdown monkey business!
PreviewMarkdown, my modern QuickLook plug-in for Markdown files, was recently updated to version 1.1.4. It was a minor change, which is why it wasn’t announced here, but the reason for the update may interest to anyone keen to understand the workings of macOS. It also highlights some inconsiderate behaviour on the part of some Mac software developers.

imageprep, my command line tool for batch-processing picture files, had a big update a week or so back — and now it has another one. With the second update imminent, I didn’t announce the first, 6.1.0, which I released to coincide with my post on writing command line utilities in Swift. That done, it’s time to shout about imageprep 6.2.0.

How To Write macOS Command Line Tools with Swift
I’ve spent a lot of time of late working on several macOS command line tools written in Swift. So I’ve gathered together the key points I’ve learned while creating and updating pdfmaker and imageprep: some best practices and ways to deliver many of the features common to programs the run at the command line.

I’ve just posted updates to a couple of applications. Both can be grabbed from my website or installed using Homebrew.

I’ve just released version 6.0.0 of imageprep, my macOS command line tool for processing batches of images. Born a shell script, imageprep has now not only finished school and graduated from college, but also has gained employment as a fully compiled application. It’s written in Swift so it’s quicker these days.

Apple Silicon survival notes — day one with an ARM Mac
You have to take your hat off to Apple: it knows how to transition from one processor architecture to another, completely incompatible one. It did it in the mid-1990s with the switch from the Motorola 680×0 series to PowerPC, then again a decade or so later when it put Intel inside new Macs. Now we get ARM.
Continue readingTap Homebrew to easily install and upgrade your own apps
The package manager I use on macOS is Homebrew, Brew for short. This is a great open source tool for installing command-line apps and utilities, and keeping them up to date. It’s essentially the Mac version of the Raspberry Pi’s apt. So much of the software I use on a regular basis — the nano text editor, Node.js, Python 3, the shellcheck shell script linter, the hugo website builder, the sass CSS wrangler and a whole load more — were added and are maintained using Brew.
