macOS 15.1 and iOS 18.1 beta certainly took the spotlight today as these updates bring the first preview of Apple Intelligence features. However, Apple has also released macOS Sonoma 14.6 to the public, which brings an important change for owners of the M3 MacBook Pro. With the update, this particular Mac now has multi-display support – a long-awaited feature.
Multi-display support now available for all M3 MacBooks
Most Apple Silicon Macs in their base configuration only support one external display connected. However, with the M3 MacBook Air, Apple has finally enabled multi-display support, allowing users to connect two external displays at the same time.
Despite sharing the same chip, the M3 MacBook Pro lacked this feature. The company confirmed to 9to5Mac in March that a future software update would also allow M3 MacBook Pro owners to use two external displays at the same time, and that promise was fulfilled today.
