These clever features paved the way for Universal Control

Universal Control is one of the best things about Apple’s ecosystem. It allows you to seamlessly use two or more Apple products with a single input device, whether that means dragging files across devices or typing on both with one keyboard. It works like magic, but as a recent interview suggests, Apple was secretly laying the groundwork for years.

Speaking to AppStories, Apple’s Vivek Bhardwaj described how Universal Control is a natural progression of some other key Apple features, including AirDrop, Handoff, and Sidecar. These tools were the “building blocks” of Universal Control, said Bhardwaj, providing a foundation for Apple to extend their capabilities.

“When you think of technologies like Bluetooth low-energy, know where devices are, all of these low-level technologies, as well as kind of this Handoff experience, Universal Control is really just the next step for continuity,” Bhardwaj explained.

If you’re unfamiliar, AirDrop lets you quickly share files between two Apple devices without resorting to email or messaging apps. With Handoff, meanwhile, you can start work on one device and instantly pick it up on another by simply opening the relevant app, while Sidecar essentially turns an iPad into a second screen for a Mac (or into a drawing pad if you have an Apple Pencil).

Once Apple had those technologies nailed down, it was able to move on to something even better — in this case, Universal Control. It’s an apt demonstration of how Apple builds its devices to work together in pretty seamless ways.

Bhardwaj went on to outline Apple’s thinking when creating the Universal Control system: “We designed Universal Control with Mac and iPad in mind. So think of it more of pairing these two devices together and then taking full advantage. Lots of Mac users have an iPad, so extending this capability to them is a really powerful experience.”

While that may be the case, you can actually use Universal Control between up to three Macs at once if you like, without requiring an iPad to be present. In that instance, it works like a built-in KVM switch, except one that doesn’t require any fiddly setup. You can’t use it to control an iPhone, though.

Still, it’s easily one of our favorite features in MacOS Monterey and iPadOS 15, and it shows how Apple’s tight-knit ecosystem can create some pretty amazing experiences.

This critical macOS flaw may leave your Mac defenseless

Apple’s macOS operating system has such a strong reputation for security that many people mistakenly believe Macs simply aren’t affected by malware. Well, Microsoft has served up a reminder that that’s not true, as the company has identified a serious vulnerability that affects one of macOS’s most important lines of defense.

According to Bleeping Computer, the bug was first reported by Jonathan Bar Or, Microsoft’s principal security researcher, who named the flaw Achilles. It is now tracked as CVE-2022-42821.

Beware — even Mac open-source apps can contain malware
A pair of glasses rests on a desk in front of multiple computer monitors filled with code.

Installing apps on a Mac is generally considered to be safer than doing so on Windows and open-source software is usually benign but there are exceptions to both of these assumptions that can do untold damage to your privacy and security.

A recent discovery by Trend Micro provides a startling example of this risk. An open-source app designed to help Mac owners with iPhone and iPad app signing has been altered to include a nasty hack that steals your Apple Keychain data. The original app is called ResignTool and it’s available for free on the popular open-source site, GitHub. The app is six years old and both the code and the ready-to-run app can be downloaded from GitHub. That isn’t the problem.

Apple Security Research website launches to protect your Mac
Apple Seurity Research website has resources for bug bounty hunters.

Apple just launched a new website that's dedicated to macOS and iOS security and there are already two blog posts that provide examples of what to expect, one providing a deep dive into memory allocation within the XNU kernel at the heart of all Apple devices, and another discussing the improved security bounty process.

The new website will undoubtedly become a critical resource for Apple security researchers, both providing information and serving as a hub for submitting bounties. The Apple Security Research website is also where you can apply for an official Apple Security Research Device (SRD) to help with identifying vulnerabilities by providing special access to what are normally protected areas of iOS.
