Nine months after its debut, Apple has finally introduced twin external display support for the M3 MacBook Pro. The latest macOS version, Sonoma 14.6, introduces this feature.
Following the upgrade, M3 MacBook Pro users can simultaneously display two external screens when the laptop is closed.
The M3 MacBook Pro can now support up to two external displays.
Apple unveiled the M3-powered MacBook Pro in late October 2023, introducing a refreshed design and significantly upgraded internal specifications. In March 2024, the corporation introduced a new model with enhanced features and showcased it with two separate exterior displays. The company has officially announced plans to deploy a software update that will enable seamless performance on the new M3 MacBook Pro.
Four months after committing to this feature, Apple is indeed following through on its pledge by introducing twin external monitor support on its most affordable Pro MacBook running macOS Sonoma 14.6. This is primarily a bug-fixing launch, marking a significant milestone in the company’s effort to resolve outstanding issues and improve overall system stability.
The M3 MacBook Air allows for simultaneous external display usage when the lid is closed, just like its bigger sibling, the M3 MacBook Pro. In most cases, when a laptop computer’s graphics card is fully utilized, it can typically support only one external monitor. The M3-powered MacBook Pro, when its lid is closed, can support up to two external 5K displays with a refresh rate of 60Hz. While the lid is open, it is capable of powering a single 6K display effectively.
While this limitation does not currently apply to the M3 Professional/Max or older M2/M1 Professional/Max MacBook models, these devices are capable of simultaneously driving up to three external displays. Older models of MacBook Pros equipped with M1 and M2 processors are limited to connecting a single external monitor.
macOS Monterey 14.6
macOS Sonoma 14.6 delivers twin monitor support in tandem with addressing several critical security flaws through patch updates. This patch addresses a security vulnerability that allowed malicious code to gain unauthorized access to sensitive personal information. You will uncover additional information regarding that.
It is essential to promptly update your Mac to the latest Sonoma edition, despite its minor nature.
