<ul data-eligibleForWebStory="true">macOS Tahoe 26 Developer Preview 1 released after WWDC 2025 seems to have removed support for FireWire I/O connection standard.Affected devices include FireWire 400 and FireWire 800-supported devices such as old hard drives, MiniDV capture devices, and early iPod models.Users reported that macOS Tahoe 26 does not recognize FireWire devices when plugged in.In the System Information app on macOS Tahoe 26, FireWire is not present in the Hardware tree, indicating intentional removal by Apple.Apple's first-generation iPod from 2001 utilized FireWire for data transfer and charging before transitioning to other connection standards.FireWire, introduced in 1995, offered data transfer speeds of 400mb/s and 800mb/s for FireWire 400 and FireWire 800, respectively.The USB standard now commonly surpasses FireWire speeds, with USB 2.0 at 480mb/s and USB 3.0 at 5gb/s.Although most modern users won't miss FireWire, a small percentage still rely on FireWire devices.Unless Apple reintroduces FireWire in future macOS Tahoe 26 updates, users may need to upgrade their legacy FireWire devices.The move to phase out FireWire may inconvenience some users, given its long history and remaining user base.
