Apple's fourth developer beta of macOS Tahoe 26.4 makes the vibrant MacBook Neo wallpapers — featuring stylized bubble-line "Mac" designs in purple, blue, pink, and yellow — available to all supported Macs, not just the new $599 laptop. The move is part of a broader macOS 26.4 update that also includes Rosetta 2 deprecation warnings, a new battery charge limit feature, Safari's compact tab layout return, and new Unicode 17 emoji.
