A macOS bug that causes TCP networking to stop working after 49.7 days
At Photon, we are developing the world’s most complete iMessage API (with RCS and SMS fallback) for agents: infrastructure that lets Agents reliably communicate through one of the most native messaging interfaces people already use. While building it, we run Mac-backed systems continuously and care a lot about making…

Using FireWire on a Raspberry Pi
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…
