Technology is always moving forward, which often means old technology gets left behind. For example, NekoMichiUBC on X has discovered that the macOS Tahoe beta lacks support for FireWire. That means that legacy devices, such as the original and 2nd-generation iPod, storage devices. cameras, and more won’t work with Macs running Tahoe.

It’s actually impressive that Apple has supported FireWire for so long, since Apple tends to drop old tech in a few years. Known by the standard name of IEEE 1394 (FireWire is Apple’s branding), Apple led its development in the late 1980s as a solution for devices that needed high-speed connectivity. In the 2000s, USB became popular and FireWire ports on Macs were eventually dropped, but support had been kept in macOS until Tahoe.

What to do if you have a FireWire device you want to use? Well, you don’t have to upgrade to Tahoe; your Mac is just fine running that older version of macOS. It means, though, that you can’t use Tahoe’s features. It also means that any features that operate between iOS 26, iPadOS 26, and Tahoe won’t be available to you, such as Call Screening. If you have a spare Mac, you can not install Tahoe on it and use it when you need to use FireWire devices, like an iPod.

If you depend on those old FireWire devices daily, it’s a good idea to upgrade, especially if it’s a storage device. That FireWire hard drive has a lot of miles on it, so its chances of failure are relatively high and increasing every day. You can probably get a faster drive with a lot more storage for a lower price than what you paid for that FireWire drive (storage was much more expensive back then).

If it’s a camera, your iPhone 15 probably produces better quality photos, though we get it, using old cameras for stylistic purposes is a thing.

There’s always a chance Apple could reinstate FireWire support in Tahoe–it’s in beta and changes always happen during the cycle. There doesn’t seem to be any technical consequence to it, but Apple likes to drop old tech as part of its proper housekeeping practice. Chances are, it’s gone, so take the time to prepare yourself before Tahoe is officially released in the fall. Learn more about macOS Tahoe.
