Article Summary: Email spoofing is when a scammer sends a message that appears to come from your domain, often to trick your clients or staff into paying a fake invoice or changing banking details. Three DNS records (SPF, DKIM, and DMARC) prove that a message really came from you and tell receiving mail servers to reject the ones that didn’t.
Apple released macOS 26.6 Tahoe, iOS 26.6, and iPadOS 26.6 with a huge number of fixes for security vulnerabilities. However, the release notes for each also include an unusual comment along the lines of “optimizes the Spotlight index in preparation for macOS 27.” At WWDC, Apple promised a rearchitected Spotlight search engine that would be faster and more reliable, so
We’ve all ended up with a collection of random USB-C cables that arrived with devices, were purchased while traveling, or were left by visitors. But you can’t look at a cable to determine its data speed, how much power it can carry, or whether it’s hampering display quality. You could buy a hardware tester, but for most people, the free
Automatic offloading of seldom-used apps can be a good strategy for recovering space on an iPhone whose storage is almost full, and iOS can do this for you in Settings > Apps > App Store > Offload Unused Apps. When you open an app that was offloaded, iOS will re-download it from the App Store so you can use it—assuming
Apple just released macOS 26.6.1 Tahoe, macOS 15.7.9 Sequoia, and macOS 14.8.9 Sonoma solely to patch a vulnerability in Screen Sharing that could allow unauthenticated connections from attackers on the network. Yes, you should update, but also take a moment to visit System Settings > General > Sharing and turn off any sharing services you aren’t actively using. Many security
Last month brought news of an unprecedented event in the evolution of AI. Several OpenAI models hacked a real company, not for malicious reasons, but because they decided that finding the test answers was more efficient than solving the problems themselves. This sounds like science fiction—it’s not far off the fictional Kobayashi Maru test in the Star Trek universe, where
We’ve become accustomed to being able to get nearly anything we want—including Macs—overnight, or at least within a couple of days. Unfortunately, surging demand from AI data centers has created a global memory shortage that’s squeezing the consumer electronics industry. As a result, we’re seeing both higher Mac prices and significantly longer delivery times as Apple competes for a limited
Generative AI is transforming software development. Large language models are good at human languages, but they’re even better at programming languages, which have much smaller vocabularies and fewer ways to combine words. Most importantly, code does something, so running it confirms whether it performs as intended. The result has been a democratization of development, much as happened with desktop publishing.
Reading articles on the Web has become fraught with distraction. Ads are terrible, of course, but publications also inundate you with navigation links, pop-ups encouraging you to subscribe, popular article lists, and more. Even worse is when an article requires multiple clicks or taps to keep reading. It’s maddening—you just want to read and get on with your day! The
Article Summary: A QR code scam, sometimes called quishing, hides a malicious web link inside a QR code. Because the link is buried in an image instead of written as text, it slips past the email filters that normally catch bad links, and scanning the code usually moves the victim onto a personal phone that sits outside the company’s security.
