Apple’s new MacBook Neo includes two USB C ports, but they do not offer the same capabilities. The port on the left side supports faster USB 3 speeds of up to 10 Gb/s, while the port on the right side closer to the trackpad supports much slower USB 2 speeds of 480 Mb/s. This difference affects how users connect certain accessories, especially external displays.
Because Apple did not label the two ports differently, some users may plug accessories into the wrong port at first. That situation becomes more noticeable when connecting an external monitor, since only the left USB C port supports external display connectivity on the MacBook Neo.
According to Daring Fireball’s John Gruber, macOS handles this situation with a simple alert. If a user connects an external display to the slower USB 2 port, macOS shows a notification that tells the user to plug the display into the other USB C port that supports display output.
Only one port supports external displays
Apple says the MacBook Neo supports one external monitor with up to 4K resolution at 60Hz. However, users must connect that display through the left USB C port because the right port does not provide the required bandwidth for video output.
That limitation comes directly from the hardware configuration. The faster USB 3 port handles both high speed data transfer and external display support, while the second port remains limited to slower USB 2 speeds.
Even though the ports look identical on the outside, macOS reduces confusion by notifying users when they connect a display to the wrong port.
MacBook Neo is currently available for pre order, with pricing starting at $599 in the United States and $499 for college students. Apple plans to release the laptop on Wednesday, March 11.
