Apple's new 140W USB-C Power Adapter included with 16-inch MacBook Pro models featuring M5 Pro or M5 Max chips has a compatibility issue affecting some customers. The adapter's subtle design change breaks compatibility with Apple's Power Adapter Extension Cable, despite the product page claiming otherwise.

The redesigned male connector features a slimmer pill-like shape instead of the previous modified C7 design, rendering it incompatible with both the extension cable and Apple's discontinued World Travel Adapter Kit. The issue creates a frustrating situation for users expecting seamless accessory compatibility with their premium laptops.

Customers in Australia and China have reported encountering the new design, while others in different regions still receive the previous version. Apple has not yet commented on the compatibility issue or provided clarification on which countries receive which version of the power adapter.
