I kind of figured this day would eventually come, especially since Apple pretty much replaced FireWire with Thunderbolt by 2012, complete with Thunderbolt now being able to support Target Disk Mode (rather than limit it to FireWire), not to mention virtually all digital audio and video devices no longer using it (when it comes to video, in addition to tape-based DV having also become obsolete in the early 2010s, some higher-end hard drive or flash memory camcorders would even include a built-in Thunderbolt port in addition to some form of USB for an even faster file transfer!). Additionally, Adobe Premiere Pro and Elements dropped support for FireWire-based DV capture for a few years now.
Besides, I almost never used FireWire with my M1 MacBook Air anyway except for digitizing some analog videotapes via my Sony Digital8 camcorder, especially since most of my videos are shot either on my Canon VIXIA HF-R600 camcorder (records onto SD card) or my iPhone 14, and importing the video from them into iMovie or Final Cut Pro or Premiere Pro or whatever is a lot easier (especially when using an SD card reader with footage from the Canon camcorder), compared to the real-time shuttling and capture of MiniDV/HDV and Digital8 cassettes. But sometimes I do use some of those camcorders for throwback-style videos, and if I do, I would generally import and edit them on an older FireWire-enabled Mac anyways as part of the throwback.
Heck, I even did so in a recent vlog talking about the 30th anniversary of MiniDV...
Complete with being shot on the MiniDV format, but for even more of a fun throwback I edited it on the Windows XP version of Adobe Premiere 6.5, on my early 2008 15" MacBook Pro's Windows XP Boot Camp partition!
So yeah, I'm all covered when it comes to legacy FireWire devices. But if I want to digitize any analog footage into my M1 MacBook Air (like a YTP sourced from one of my VHS tapes), I may then look into getting a decent USB-based analog-to-video capture device for the Mac, such as Elgato's.
