New macOS update time! macOS 10.15.5 is out now with a new battery health feature Apple released macOS Catalina 10.15.5 today, adding a new battery health feature and new FaceTime options. That battery health feature could extend the life of your MacBook’s battery. Lithium-ion batteries, like the ones in a MacBook, slowly age over time, which means they typically begin to hold less of a charge as the computer gets older. Apple’s new battery health feature in macOS is designed to slow that aging process so that your battery will hold more charge over a longer period of time. Here’s how the feature works behind the scenes, as described by my colleagues Dieter Bohn and Jacob Kastrenakes last month: ...in certain cases, seeing 100 percent battery life in your menu bar may not necessarily mean it’s the maximum your battery could charge to. Instead of meaning that it’s charged to 100 percent of what the battery could take, it will now mean it’s charged to 100 percent of what the battery should take to maximize its lifespan. The new battery health feature will be turned on by default for new MacBooks that ship with macOS 10.15.5 or after you upgrade to macOS 10.15.5 if you’re using a MacBook that supports Thunderbolt 3 (which is any MacBook Pro released in 2016 or later or any MacBook Air released in 2018 or later). macOS 10.15.5 will also let you turn off the feature in group FaceTime calls that changes the size of the portrait of the current speaker, adds controls to let you better calibrate the Pro Display XDR, and has other bug fixes and improvements.

Just stop using FB's WhatsApp, if you care about privacy Signal announces new face-blurring tool for Android and iOS Encrypted messaging app Signal has announced a new face-blurring tool that will be incorporated into the latest Android and iOS versions of the software. Users sharing pictures through the app will be able to quickly blur faces, adding another layer of privacy to pictures, though not necessarily hiding the subject’s identity completely. In a blog post announcing the update, Signal co-founder Moxie Marlinspike linked the update to the worldwide protests against racism and police violence sparked by the killing of George Floyd by law enforcement. These protests have led to record downloads for Signal, which uses end-to-end encryption to make messages harder to intercept. “We’ve also been working to figure out additional ways we can support everyone in the street right now,” writes Marlinspike. “One immediate thing seems clear: 2020 is a pretty good year to cover your face.” When you take a picture through Signal and select the Blur option in the toolbar, the app will automatically detect any faces it spots in your image. If it misses any, users can simply blur out faces by hand, or blur any other features they want to hide. All processing is done on-device, meaning uncensored images never leave the user’s phone. Although blurring faces in photographs certainly makes pictures more private, it’s by no means a foolproof way of anonymizing images and hiding someone’s identity. Some blurring and pixellation methods can be reversed with the right tools, for example. And anyone seeking to identify someone in a picture can work from other information, such as clothing and tattoos, which can be compared with other, un-blurred images. Even if attendees at a protest, for example, hide the identity of fellow protestors, that doesn’t mean other groups and individuals will do the same. Surveillance cameras, police body cameras, and press photographers are all capturing images. Ultimately, the best way to obscure your identity is to take matters into your own hands and wear a mask.

Smartphones are bad for you. We need to go back to the good old rotary phones! Earlier this year, Justine Haupt revealed a custom cellphone she built that eschewed unwanted battery-killing distractions like a touchscreen. In its place was an old-school rotary dial for placing calls, and while it looked antiquated, there were apparently enough people as fed up with the state of modern smartphones that Haupt has created a new version that she will actually build and sell. Haupt’s original rotary cellphone was created with an open source design that allowed anyone to build their own, with firmware, build notes, and even the 3D models for printing the custom housing made available for download on their website. To make the build easier, Haupt created a starter kit offering the 3D printed housing for $50 (straight out of the 3D printer) as well as the cellphone’s mainboard for $90. But there were still lots of additional components that needed to be sourced to complete the build, including the dial that Haupt salvaged from a slim Western Trimline telephone. Realizing the appeal of a distraction-free cellphone that excels at actually making calls (just look at the size of that antenna) extends well beyond hardware hackers and tinkerers, Haupt is currently developing a “mark 2" version of the design that will be available as a ready-built device for those who don’t know the first thing about soldering. In addition to an upgrade from 3G to 4G which ensures the right networks will be active for at least another 10 years, the new version will include a larger electronic paper display, newly manufactured rotary dial parts instead of old salvaged hardware, and an SD card slot allowing a contact list to be added by just uploading a text file full of names and numbers. Haupt is also teasing, “another VERY cool feature but won’t announce it until I’m sure I can do it” for their new rotary cellphone which remains a complete mystery for the time being. But a listing for the device on the website for Haupt’s new robotics company called Sky’s Edge claims it could be available as early as September. You can’t pre-order it yet, and it’s safe to assume the pandemic will probably result in some minor delays, but if you’re interested you can subscribe to updates on the project’s development, and notifications for when it’s finally available.
