Under the hood, macOS relies on Unix, which is a multi-user operating system. That’s why a Mac can host multiple users who, as long as they don’t know each other’s passwords, cannot see each other’s files. To maintain each user’s privacy, macOS relies on permissions that specify who can do what with any given file […]

A side effect of the pandemic is that online videoconferencing improved drastically. Video calls happened before 2020, but videoconferencing wasn’t an everyday activity for most people. Now, with many people working remotely or in a hybrid model, it’s a fact of business life. To support videoconferencing tools, Apple has extended macOS’s basic webcam and microphone […]

Apple’s prices for Thunderbolt, USB-C, and Lightning cables often seem unnecessarily high. $69 for a Thunderbolt 4 cable or $19 for a simple USB-C to Lightning cable? Unfortunately, when it comes to cables, you often get what you pay for. Happily, other reputable hardware manufacturers like Anker, Belkin, and OWC sell quality cables for less […]

We Apple users tend to believe that our devices usually last longer—both physically and functionally—than Windows PCs and Android smartphones. For instance, Apple’s current operating systems work on nearly all Macs, iPhones, and iPads introduced in 2018 and later, albeit with some feature loss on the oldest devices. In a white paper entitled “Longevity, by […]

Let’s say you’re writing documentation to help colleagues use Preview to edit images, sign PDFs, and convert graphics. (A worthy task for which they will thank you!) For this documentation, you want to include the Preview app’s icon so they know what to look for in the Applications folder and Dock. To copy a high-resolution […]

Is your child heading off to college soon? They’ve undoubtedly been using a computer throughout high school, though now is a good time to look at getting them a new one, especially if theirs is old or unreliable, is shared with other family members, or was a school loaner. If you haven’t been keeping up […]

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 colors of the screen as […]

If you have trouble finding particular items across multiple shelves of books, labeled boxes, or anything else that’s clearly identified with a text name, take carefully composed photos that capture all the titles without glare. Later, you can search for any text in those photos to find them—tap the Search button in Photos on the […]

Most people like smart quotes and dashes, at least most of the time. Your Mac is probably set up to turn the single (') and double (") hash marks and double hyphens (--) that you type into the apostrophes (’) and single smart quotes (‘’), double smart quotes (“”), and em dashes (—) used in […]

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 […]

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 […]

You can change the resolution of your Mac’s screen—how many pixels appear—to make text and graphics larger and easier to see or smaller to fit more content onscreen. In System Settings > Displays, Apple shows thumbnails for five likely possibilities. Hover the pointer over a thumbnail to see its numeric resolution underneath. If you prefer […]

Although many of us think of Messages as an iPhone app, Apple’s platform integration lets you read and reply to conversations in Messages on other Apple devices, including the Mac and iPad. All your devices must have the correct settings to make this work reliably. We regularly hear from users who don’t see all their […]

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? It provides quick access to definitions and synonyms in the New Oxford American Dictionary and the Oxford American Writer’s Thesaurus, along with definitions of Apple-specific words […]
