The generic external drive icon in macOS 26.1 beta 1 still hasn’t been updated. Beta 2, maybe? Either way, inexplicable and worrying lack of attention to detail from Apple.

Three drive icons on the macOS 26.1 beta 1 desktop: Macintosh HD, External Data, and OrbStack. Macintosh HD and OrbStack have updated icons to fit the Tahoe look and feel, while the external data drive continues to display an icon from previous versions of macOS.
