Research suggests that exposure to blue light fools your body into thinking it’s daytime, making it harder to fall asleep if you work late on a Mac with a bright white (which has a lot of blue light) screen. To help, a macOS feature called Night Shift subtly changes the screen’s colors as the sun…

When your team or family shares access to a single account (such as for banking or social media, which seldom offer multi-user access), using two-factor authentication via SMS is awkward—whose phone receives the 2FA codes? One solution is to use an authentication app. Authentication apps are more secure, and multiple people can add 2FA support…

Spam filters work pretty well—99% of the messages in your spam mailbox are probably spam. But it’s frustrating to miss an important message that was caught by an overeager spam filter. Here’s an easy way to find many good messages, also known as “ham,” amidst all the spam. Think of keywords that might appear in…

We all make mistakes, which is why Undo exists. Immediately choose Edit > Undo or press Command-Z to undo your last change. Most Mac apps support multiple levels of Undo, so you can keep pressing Command-Z to revert change after change. However, suppose you delete a table in your Pages document, but 30 minutes and…

By default, the battery icon in your Mac laptop’s menu bar shows how full your battery is. Clicking it reveals the exact percentage, but you can also set macOS to display the battery percentage next to the icon. The setting isn’t where you might expect in System Settings > Battery. Instead, you’ll find it in…

The latest versions of the Mac and iPad apps in Apple’s iWork suite—Pages 14, Keynote 14, and Numbers 14—have gained a helpful feature: non-contiguous text selection. By holding down the Command key, you can select chunks of text that aren’t next to each other. For example, imagine you want to make the first part of…

You may be used to Mac apps using red underlines to mark misspelled words, but did you know that macOS has also long included a fully featured Dictionary app?
