Apple’s latest MacOS Big Sur beta brings 4K YouTube to Safari

If you’re a fan of the Safari web browser on your Mac, Apple just gave YouTube video playback a major upgrade in its latest macOS beta release. Now available for download, developers on the macOS Big Sur beta 4 can finally playback YouTube videos in 4K UHD resolution using Apple’s Safari browser.

Apple published details about the feature change in its Big Sur beta 4 documentation, noting that the software brings “support for 4K HDR playback of YouTube videos” in Safari and Webkit.

Prior to today’s release, YouTube video was capped at just 1080p FHD resolution when using Safari. This meant that if you wanted to play YouTube videos at resolutions greater than FHD, you had to choose an alternate browser, like Google’s Chrome. If all goes well during Apple’s beta testing period, Big Sur is expected to be released this fall for all consumers.

This change is especially notable given Apple’s push for higher resolution displays in recent years with Retina Displays appearing on smartphones, tablets, and the Mac. This means that if you own Apple’s iMac with Retina 4K Display, iMac with Retina 5K Display, iMac Pro with Retina 5K Display,  or Apple’s studio-grade Pro Display XDR panel with a Retina 6K Display, you can edit and playback YouTube videos in resolutions up to 4K.

Initially announced earlier this summer at Apple’s Worldwide Developers Conference event, macOS Big Sur introduced a number of new features, including new icons, an updated menu bar, redesigned sheets, and a refreshed Notification Center — changes that will helps to unify Apple’s desktop macOS operating system with its mobile iOS and iPad OS platforms. In fact, Apple views the changes introduced with Big Sur significant enough to warrant a numerical jump to its macOS platform, moving from macOS 10 for desktops — which was initially introduced in 2001 — to macOS 11.

Big Sur is also the first operating system that kicks off Apple’s support for its own custom in-house silicon as Apple moves away from Intel. As Apple transitions to ARM-based processors for its Mac, we can likely expect to see Apple port over more features from its mobile platforms.

If you want to give Big Sur a spin ahead of its commercial release, you can begin by enrolling your Mac in Apple’s software preview program. However, before you do that, be sure to read Apple’s documentation for the latest beta release to see what problems or issues you may encounter during testing. Although Apple announced that Big Sur will be coming to supported Macs this fall, the company did not give a specific launch date.

Quick summary

Two years ago, I had the chance to test out the Viture Pro smart glasses. I was impressed by the chic design and the stunning display units, but there were a few minor hiccups that kept them from becoming an instant buy for XR fans. The asking price of $459, ultimately, made them a tough recommendation for anyone who is not a diehard enthusiast or doesn't have the spare cash to spend. The successor, however, is an altogether different beast.

Your Mac might have a screen sharing problem, and hackers already know about it
A patch is only useful once you install it.
macOS Tahoe 26 public beta running on the M4 MacBook Air 15

If you've been putting off that macOS update sitting in your notifications, this is the week to stop and install it. 

Apple quietly patched a serious screen sharing flaw in macOS earlier this month. While that usually means the issue is resolved, new evidence shows hackers already broke into unpatched Macs, hijacked them, and used them for cryptocurrency mining before the fix shipped.

The FCC has a track record of using its Covered List to squeeze Chinese tech out of American markets, and robots just became its newest target. Foreign-made humanoids, quadrupeds, and even robot vacuums now need to be mostly built in the U.S. to sell here (via Rest of World). 

So what does the new rule actually require?
