Apple plans to release new MacBook Pro and MacBook Air models with scissor keyboards in the second quarter of 2020, according to a new research note today from analyst Ming-Chi Kuo, obtained by MacRumors.

Kuo did not comment on the size of the new MacBook Pro, but he is possibly referring to the 14-inch model that he has previously mentioned given that the 16-inch MacBook Pro was only released four months ago. The new 14-inch model would likely replace the 13-inch MacBook Pro, which would be discontinued.

Kuo expects the new MacBook Pro and MacBook Air models to have various cost optimizations, but he said users will not notice any difference.

The current 13-inch MacBook Pro and MacBook Air are still equipped with butterfly keyboards that can suffer from issues such as sticky or unresponsive keys after prolonged use, which prompted Apple to initiate a free repair program worldwide in 2018. Apple finally solved this problem by reverting back to a scissor mechanism with the new Magic Keyboard on the 16-inch MacBook Pro, which has proven far more reliable.

Kuo himself offered praise for the 16-inch MacBook Pro, noting that customer response to the notebook has been better than expected.

As for the COVID-19 coronavirus pandemic, Kuo believes that operations at MacBook-related suppliers will improve significantly starting in late March, paving the way for mass production of the new MacBook Pro and MacBook Air models.

If this information proves to be accurate, then Apple's entire notebook lineup should feature scissor keyboards by the end of 2020.
