Using FireWire on a Raspberry Pi

2026-03-25 00:00:00

After learning Apple killed off FireWire (IEEE 1394) support in macOS 26 Tahoe, I started looking at alternatives for old FireWire equipment like hard drives, DV cameras, and A/V gear.

I own an old Canon GL1 camera, with a 'DV' port. I could plug that into an old Mac (like the dual G4 MDD above) with FireWire—or even a modern Mac running macOS < 26, with some dongles—and transfer digital video footage between the camera and an application like Final Cut Pro.

The best laptop Apple ever made

2026-03-20 22:00:00

Today I posted a video titled The best laptop Apple ever made, and tl;dw1 it's the 11" MacBook Air.

I acknowledge in the video my pick is slightly subjective, and I also asked a number of other YouTubers which Mac laptop they consider the best (or at least most influential). If you don't want to watch the video, I'll summarize their choices here:

Restoring an Xserve G5: When Apple built real servers

2026-03-13 22:00:00

Recently I came into posession of a few Apple Xserves. The one in question today is an Xserve G5, RackMac3,1, which was built when Apple at the top—and bottom—of it's PowerPC era.

This isn't the first Xserve—that honor belongs to the G41. And it wasn't the last—there were a few generations of Intel Xeon-powered RackMacs that followed. But in my opinion, it was the most interesting.

Unfortunately, being manufactured in 2004, this Mac's Delta power supply suffers from the Capacitor Plague. The PSU tends to run hot, and some of the capacitors weren't even 105°C-rated, so they tend to wear out, especially if the Xserve was running high-end workloads.

Can the MacBook Neo replace my M4 Air?

Many of us wonder if the MacBook Neo is 'the one'.

Because I have a faster desktop (currently a M4 Max Mac Studio), I've always used a lower-end Mac laptop, like the iBook or MacBook Air, for travel. I've used MacBook Pros in the past, but I like the portability of smaller, cheaper models.

In fact, my favorite Mac laptop ever was the 11" Air.

A PTP Wall Clock is impractical and a little too precise

2026-03-06 23:00:00

After seeing Oliver Ettlin's 39C3 presentation Excuse me, what precise time is It?, I wanted to replicate the PTP (Precision Time Protocol) clock he used live to demonstrate PTP clock sync:

I pinged him on LinkedIn inquiring about the build (I wasn't the only one!), and shortly thereafter, he published Gemini2350/ptp-wallclock, a repository with rough instructions for the build, and his C++ application to display PTP time (if available on the network) on a set of two LED matrix displays, using a Raspberry Pi.

I built a pint-sized Macintosh

2026-03-03 05:15:00

To kick off MARCHintosh, I built this tiny pint-sized Macintosh with a Raspberry Pi Pico:

Pico Micro Mac running System 5.3

This is not my own doing—I just assembled the parts to run Matt Evans' Pico Micro Mac firmware on a Raspberry Pi Pico (with an RP2040).

The version I built outputs to a 640x480 VGA display at 60 Hz, and allows you to plug in a USB keyboard and mouse.

Since the original Pico's RAM is fairly constrained, you get a maximum of 208 KB of RAM with this setup—which is 63% more RAM than you got on the original '128K' Macintosh!
