Between apps, photos, videos, music, and downloads, it’s easy to fill up your Mac’s drive, particularly one with just 128 or 256 GB of drive space. macOS warns you when you get too low on space, but those warnings may come late—for optimum Mac performance, we recommend you keep at least 10–20% of your drive free for new downloads and …

We’ve helped some clients recently with networking problems that seemed to be related to Internet connections. Most notable was intermittently slow Internet performance, causing the client to call their ISP to upgrade to a higher bandwidth connection with guaranteed throughput. But that extra monthly expense turned out to be unnecessary once we tracked the problem to a malfunctioning cable modem. …

The European Union has for many years required that websites—at least those serving European users—gain informed consent before storing the personal data of those users. That data includes cookies, which are bits of information stored in Web browsers that websites can read and write. Cookies are widely used for remembering login information, saving user account information, maintaining a shopping cart, …

We periodically field questions about password-protecting a PDF to prevent the wrong people from reading it. Lawyers want to ensure that drafts of legal documents don’t fall into the wrong hands, financial advisers want to keep confidential financial information private, and authors want to prevent their writing from being shared broadly on the Internet. Others don’t worry so much about …

September is here, and with it, Apple’s latest iPhones and Apple Watches. At its Wonderlust event on September 12, Apple threw back the curtains on the new iPhone 15 lineup, Apple Watch Series 9, and Apple Watch Ultra 2.

Apple’s Preview is a surprisingly capable graphics editor for making quick changes to screenshots and other illustrations, but it lacks a built-in way to delete content while leaving the background. Here’s the workaround—select a rectangle of the background color, copy it, paste it, and then move it over the undesirable content—as shown in the After screenshot below, where blue selection …

In macOS 13 Ventura, Apple replaced the creaky System Preferences with System Settings, which uses a more iOS-like interface. Many people find System Settings overwhelming, partly because they had memorized where to look in System Preferences (but System Settings has many other design flaws as well—it’s not your fault). We have two recommendations to make it more easily navigable. First, …

We’re hearing about new hires who receive an email or text from someone claiming to be the CEO of their new company, asking the employee to carry out some small task like sharing personal information, purchasing a gift card for a client, or wiring funds to another business. The new employee, eager to make a good impression and lacking the …

Keyboard shortcuts are a productivity win, but they can cause confusion if something unexpected happens when you inadvertently press some system-wide key combination. For instance, you might be taken aback if you accidentally press Control-Option-Command-8 and all the colors on your Mac screen suddenly invert. Although Apple has pages listing shortcuts and the KeyCue utility can list them all for …

It has been a tough year for extreme weather events. While the connection between weather and technology may seem tenuous, heat waves, high winds, and lightning strikes can play havoc with all sorts of powered and networked electronic devices. Anything that causes power fluctuations—spikes, surges, sags, brownouts, and blackouts—can hurt your tech gear. Protecting your most vulnerable devices doesn’t have …
