With less than 24 hours away until Apple's “Hello again” Mac event, images of an unreleased MacBook Pro found in the latest macOS Sierra 10.12.1 update have all but confirmed a rumored OLED touch bar replacing the row with hardware function keys.
The Internet immediately complained about the apparent loss of the hardware Escape key that seems to have fallen victim to these programmable OLED keys. While the OLED Bar could display a soft-Escape key in the left corner, users can now assign its function to one of the hardware modifier keys.
As Jeff Geerling first noted yesterday, the latest macOS 10.12.1 Sierra update now conveniently lets you remap an Escape action to a Caps Lock, Control, Option or Command modifier key—which wasn't possible in earlier macOS editions.
