an SD card reader, MagSafe charging, and a higher base memory. Other additions include a Liquid Retina XDR display with thinner bezels and an iPhone-like notch, ProMotion variable refresh rate, a 1080p webcam, Wi-Fi 6, 3 Thunderbolt ports, a 6-speaker sound system supporting Dolby Atmos, and support of multiple external displays. These new models feature a thicker and more-squared design than their Intel-based predecessors. The keyboard features full-sized function keys, with the keyboard set in a "double anodized" black well. The MacBook Pro branding has been removed from the bottom of the display bezel and is engraved on the underside of the chassis instead. The models' appearance has been compared to the Titanium PowerBook G4 produced from 2001 to 2003. In January 2023, the 14-inch and 16-inch models were updated. The new models come with the Apple M2 Pro and M2 Max, can be configured with up to 96 GB of RAM (up from 64 GB), support HDMI 2.1 that can drive an 8K external display (the 2021 models supported HDMI 2.0), and support faster Wi-Fi 6E. Apple advertises the new 16-inch model with "up to 22 hours" of battery life, which it says is the "longest battery life ever" in a Mac.
