On every MacBook Air (and all newer MacBook Pros), if you hit the “Caps Lock” key, nothing will happen. In order to prevent accidental keystrokes, Apple only turns on Caps Lock if you hold the key for a bit longer.
Apple products have always been known for their quality design and attention to detail. Many of these details go unnoticed by the average Apple user, or are only useful to a relative handful of people using the product. Some features are handy while others are purely cosmetic, but Apple included them anyway.
Here are some examples of the best of these little design flourishes.
Apple has a patent dating back to 2002 for a “Breathing Status LED Indicator.” The patent describes a “blinking effect of the sleep-mode indicator that mimics the rhythm of breathing which is psychologically appealing.”
When engaging the voice dictation feature on newer Mac laptops, Apple automatically slows the internal fan speed to better hear your voice.
When you turn on “Do Not Disturb” mode, a tiny crescent moon appears at the top of your screen. Not too impressive by itself, but when you toggle the setting on and off, you’ll notice that a tiny eclipse animation happens right before your eyes.
The next time you adjust the brightness or volume on your iPhone using the control center, give the dials a hard flick and watch as they continue to move even after your finger stops. If you flick hard enough, they’ll even bounce back a bit.
