Apple has released macOS Tahoe 26.3 public beta 2, the latest test build ahead of a wider 26.3 rollout later this month. The first 26.3 beta arrived in mid-December, and this second public beta follows Apple’s fresh round of January beta releases after the holiday break.
Public beta 2 carries build number 25D5101c. For reference, beta 1 was 25D5087f, so this update looks like a standard iteration focused on polish rather than big additions.
