Apple has pushed the second macOS Tahoe 26.3 beta to its developer community, arriving roughly four weeks after the first test build. To install, developers open System Settings, select General, then tap Software Update and enable the beta channel with a free developer account. No new features have been confirmed; the initial beta revealed only minor tweaks, and the latest build appears to be a polish pass.

Historically, Apple releases a public version of a macOS update near the end‑January, so a late‑January launch is plausible. Enterprise IT departments often mirror the developer seed to certify internal hardware fleets, so the beta’s stability directly influences corporate upgrade schedules. Developers can report issues through Apple’s Feedback Assistant, which aggregates data to prioritize fixes before the public launch.
