Top insider revealed a big M4 MacBook Pro upgrade that Apple kept secret

Unlike the previous MacBook Pro updates, Apple really revamped the new M4 series. Even though it might look the same from the outside, this laptop has several new perks—and I'm not even talking about the faster processor.

However, one of the most interesting changes went unnoticed until display analyst Ross Young revealed that Apple is using a new panel for the M4 MacBook Pro. According to Young, Apple adopted Quantum Dot technology for the first time in a Mac's display. Previous iterations used a red KSF phosphor film.
