Apple Releases iOS 16.6 Beta Just Days Before WWDC
Developers and public beta testers can download the update now.

Apple released iOS 16.6 beta 2 to public beta testers Thursday, a few days before the company holds its Worldwide Developers Conference. We don’t expect many new features with iOS 16.6 since Apple is expected to announce iOS 17 at WWDC.

New iOS features can be fun, but we recommend only downloading a beta on something other than your primary phone just in case the new software causes issues. Apple also provides beta testers with an app called Feedback. Testers can notify Apple of any issues in the new software with the app, that way the problem can be addressed before general release.
Here’s what could be coming to your iPhone with iOS 16.6.
iMessage Contact Key Verification
Apple announced iMessage Contact Key Verification in December 2022 alongside Security Keys for your iCloud account.
«With iMessage Contact Key Verification, users who face extraordinary digital threats … can choose to further verify that they are messaging only with the people they intend,» Apple wrote in a news release at the time.
The first iOS 16.6 beta appeared to include some of the framework for Contact Key Verification, but with iOS 16.6 beta 2, that seems to have disappeared. If you went to Settings and searched for «Contact Key Verification» in the first iOS 16.6 beta, you could see an option for the feature. But that option vanished in the second iOS 16.6 beta.
More Beats Studio Buds icons
The second iOS 16.6 beta adds two new color icons for Beats Studio Buds, according to the website Gadget Hacks. The new color icons are for the ivory and transparent Beats Studio Buds, so if you have either of those earbuds you should see those icons on your iPhone with the latest beta.
New iCloud for Windows prompt
Gadget Hacks also reports iOS 16.6 beta 2 adds a new prompt when you try to log into iCloud for Windows when your iPhone and Windows computer aren’t on the same Wi-Fi network. The new prompt reportedly advises you to use a different network and that your iPhone and Windows computer need to be on the same network.
Apple hasn’t announced a release date for iOS 16.6. Apple might include more features in iOS 16.6, and there’s no guarantee that these features will be included in the update.

Apple, I’m (Sky) Blue About Your iPhone 17 Air Color
Commentary: The rumored new hue of the iPhone 17 Air is more sky blah than sky blue.

I can’t help but feel blue about the latest rumor that Apple’s forthcoming iPhone 17 Air will take flight in a subtle, light-hued color called sky blue.
Sky blue isn’t a new color for Apple. It’s the featured shade of the current M4 MacBook Air, a shimmer of cerulean so subtle as to almost be missed. It’s silver left too close to an aquarium; silver that secretly likes to think it’s blue but doesn’t want everyone else to notice.
Do Apple employees get to go outside and see a real blue sky? It’s actually vivid, you can check for yourself. Perhaps the muted sky blue color reflects a Bay Area late winter/early spring frequent layer of clouds like we typically see here in Seattle.
«Who cares?» you might find yourself saying. «Everyone gets a case anyway.» I hear you and everyone else who’s told me that. But design-focused Apple is as obsessive about colors as they are about making their devices thinner. And I wonder if their heads are in the clouds about which hues adorn their pro products.
Making the case for a caseless color iPhone
I’m more invested in this conversation than most — I’m one of those freaks who doesn’t wrap my phone in a case. I find cases bulky and superfluous, and I like to be able to see Apple’s design work. Also, true story, I’ve broken my iPhone screen only twice: First when it was in a «bumper» that Apple sent free in response to the iPhone 4 you’re-holding-it-wrong Antennagate fiasco, and second when trying to take long exposure starry night photos using what I didn’t realize was a broken tripod mount. My one-week-old iPhone 13 Pro slipped sideways and landed screen-first on a pointy rock. A case wouldn’t have saved it.
My current model is an iPhone 16 Pro in black titanium — which I know seems like avoiding color entirely — but previously I’ve gone for colors like blue titanium and deep purple. I wanted to like deep purple the most but it came across as, in the words of Patrick Holland in his iPhone 14 Pro review, «a drab shade of gray or like Grimace purple,» depending on the light.
Pros can be bold, too
Maybe the issue is too many soft blues. Since the iPhone Pro age began with the iPhone 11 Pro, we’ve seen variations like blue titanium (iPhone 15 Pro), sierra blue (iPhone 13 Pro) and pacific blue (iPhone 12 Pro).
Pacific blue is the boldest of the bunch, if by bold you mean dark enough to discern from silver, but it’s also close enough to that year’s graphite color that seeing blue depends on the surrounding lighting. By comparison, the blue (just «blue») color of the iPhone 12 was unmistakably bright blue.
In fact, the non-Pro lines have embraced vibrant colors. It’s as if Apple is equating «pro» with «sophisticated,» as in «A real pro would never brandish something this garish.» I see this in the camera world all the time: If it’s not all-black, it’s not a «serious» camera.
And yet I know lots of pros who are not sophisticated — proudly so. People choose colors to express themselves, so forcing that idea of professionalism through color feels needlessly restrictive. A bright pink iPhone 16 might make you smile every time you pick it up but then frown because it doesn’t have a telephoto camera.
Color is also important because it can sway a purchase decision. «I would buy a sky blue iPhone yesterday,» my colleague Gael Cooper texted after the first rumor popped online. When each new generation of iPhones arrive, less technically different than the one before, a color you fall in love with can push you into trading in your perfectly-capable model for a new one.
And lest you think Apple should just stick with black and white for its professional phones: Do you mean black, jet black, space black, midnight black, black titanium, graphite or space gray? At least the lighter end of the spectrum has stuck to just white, white titanium and silver over the years.
Apple never got ahead by being beige
I’m sure Apple has reams of studies and customer feedback that support which colors make it to production each year. Like I said, Apple’s designers are obsessive (in a good way). And I must remind myself that a sky blue iPhone 17 Air is a rumored color on a rumored product so all the usual caveats apply.
But we’re talking about Apple here. The scrappy startup that spent more than any other company on business cards at the time because each one included the old six-color Apple logo. The company that not only shaped the first iMac like a tipped-over gumdrop, that not only made the case partially see-through but then made that cover brilliant Bondi blue.
Embrace the iPhone colors, Apple.
If that makes you nervous, don’t worry: Most people will put a case on it anyway.

Astronomers Say There’s an Increased Possibility of Life on This Distant Planet
Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.
The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea.
According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»
The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»
Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.
Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»
K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.
More research to do on finding life on K2-18b
The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.
«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»
Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»
The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»
As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.
«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»
