At the beginning of a recent photo walk with a Nikon representative, I was told it was only a matter of time before I became a “birder”. Because eventually every photographer runs out of things to take photos of and is left with only one subject to master: birds. Which, because of advancements in sensor technology, have become a much easier target.

Nikon’s new $2,500 Z6 III has the world’s first partially stacked CMOS sensor
It was on this same photo walk that I got a few hours with the new $2,500 Nikon Z6 III. And the big news in this camera is its 24.5-megapixel partially stacked CMOS sensor. This is the first camera, ever, to employ this technology. Instead of the circuit parts and pixel area both stretching the full corner-to-corner dimensions of the image sensor and sitting on top of each other, as in the more expensive Nikon Z9 or Nikon Z8, or not being stacked at all, as in the previous Nikon Z6 II, the Z6 III’s circuit parts are stacked as bars on the top and bottom of the pixel area.
It results in higher continuous shooting rates, faster autofocus, higher video frame rates, and less rolling shutter effect than the previous Z6 II, with its BSI CMOS sensor in e-shutter mode. But it also means that the Z6 III is not as speedy as the more premium Z8 or Z9 with their fully stacked sensors. In simple terms, partially stacking the sensor allows Nikon to keep this camera’s price below that of the Z8 and Z9 while also much improving the performance of it over the previous generation.
The other important updates are the Z6 III’s incredibly bright electronic view finder that can reach a peak brightness of 4,000 nits and the cameras ability to film 6K RAW video at up to 60fps and 4K RAW up to 120fps. Nikon is also promising Z8 level build quality, which means the camera is dust and moisture sealed and rated for operation down to 14°F/−10°C. Simply put, Nikon builds very resilient cameras that don’t skimp on specs. And also cameras that can turn any photographer into a birder.
I chose the Staten Island Ferry for my photo walk with the Z6 III because of its endless opportunities for people watching and incredible views of lower Manhattan and the Statue of Liberty. Match that with the boat’s iconic orange color and you are guaranteed at least a few great shots. What I had never paid much attention to before were all of the birds using the boat’s slipstream to move across the harbor.
While the Z6 III does not have a dedicated bird focus mode, Nikon claims that its autofocus is 20% faster than the Z6 II and has an extended range down to -10EV, meaning it is more sensitive even in lowlight conditions. And while on the back of the ferry, it had absolutely no trouble locking onto birds. Within minutes of taking off from Lower Manhattan I was whipping the Z6 III from left to right attempting to capture seagulls. Eventually I smartened up and framed One World Trade Center and waited for a bird to cross my frame. And as soon as a bird would enter the camera locked right the moving object that was a seagull. Within minutes I had shot well over 100 photos.

There of course then came the moment I thought “what the hell am I going to do with all these photos of birds”. Which is why I would like to thank you all for clicking through the above slideshow and giving my new found passion for bird photography a reason to exist.
Much like the Z8 and Z9, Nikon increasingly makes cameras that are so responsive and intuitive that you no longer have to spend as much time thinking about problems such as focus, hand shake, or shutter speed. You can quickly point the camera in any direction and it will capture something in focus.
That being said, there is only so much I could test in my few hours with this camera. I didn’t have a low light environment to test the ISO ranges or low light autofocus, I didn’t have multiple subjects to test skin tone representation on, and I didn’t have ND filters in order to get a proper video exposure for testing 6K RAW. So while I had a lot of fun, and am now a certified “birder” there is certainly a lot more testing that needs to be done on this new partially stacked sensor technology. But in my short time with it, I can confidently say that in no way did it feel like a step back. The Z6 III will be available starting today for $2,500.

Spotify’s new audiobook recap feature uses AI to remind you of the story so far
Spotify is launching a new AI feature for audiobooks that summarizes what you’ve already heard without needing to rewind. The company likens the feature, called Recaps, to a “previously on” segment at the start of episodes in a TV series.
Recaps will be available automatically in the iOS app for a limited number of English-language audiobooks, with plans to expand to more audiobooks in an unspecified time frame. While the Recap button is always present on supported titles, you will have to listen to more than 15–20 minutes of the audiobook to get a summary, according to the Spotify blog post on the feature. After that, Recaps will be “regularly updated” as you progress through the audiobook. It’s “designed to help people finish the books they start,” the company says in the blog.
True-crime author J.H. Markert called the feature “an audio bookmark that speaks” in the company blog. “Using it once blew my mind. As sophisticated as it is smart, this feature is a must for any audiobook lovers out there.”
Spotify made clear that Recaps uses AI, but maintains that the original works — including the book content and voice narration — remain protected. “We are not using audiobook content for LLM training purposes or voice generation, and Recaps do not replicate narration or replace the original audiobook in any way,” Spotify’s research director of LLMs, Paul Bennett, wrote in the blog post.

Apple passkey technology transforms Mac security with biometric authentication, encrypted storage
NEWYou can now listen to Fox News articles!
Your Mac holds a lot more than just files. It carries your personal information, payment data, messages and every online account you access. Keeping that information safe starts with how you sign in. For years, passwords have been the standard way to protect accounts, but they are also one of the weakest links in digital security. They can be guessed, stolen or reused across multiple sites.
Apple’s introduction of passkeys marks a major step forward. Instead of relying on something you need to remember, passkeys rely on something you have (your trusted Apple device) and something you are, like your fingerprint or face. Together with iCloud Keychain and two-factor authentication, passkeys create a seamless and much safer way to secure your Mac and your digital life.
What are passkeys?
Passkeys are a modern alternative to passwords. They use public key cryptography to let you sign in without ever creating or typing a password. When you register for an account using a passkey, your Mac creates two unique keys. One is public and stored by the website or app, and the other is private and stays securely on your device.
The public key is not sensitive information. The private key, on the other hand, never leaves your Mac and is protected behind your device’s security features. When you sign in, Touch ID or Face ID confirms your identity before your Mac uses the private key to authenticate you. This process prevents phishing and password leaks because no shared secret is ever transmitted to the website.

HOW TO USE PASSKEYS TO KEEP YOUR COMPUTER SAFE

How Apple keeps passkeys secure
Passkeys are stored and synced across your devices through iCloud Keychain, which is protected by end-to-end encryption. This means that not even Apple can access your passkeys or passwords. iCloud Keychain also has built-in protection against brute force attacks, even if someone were to gain unauthorized access to Apple’s servers.
If you lose your devices, you can still recover your passkeys through iCloud Keychain recovery. To do this, you must sign in with your Apple ID and password, verify your identity with a code sent to your trusted number and confirm using your device passcode. The system limits the number of attempts, and if too many failed attempts occur, the recovery record is locked or destroyed to prevent misuse.
You can also set an account recovery contact to make sure you never lose access, even if you forget your Apple ID password or device passcode. This multi-layered design ensures that your data remains secure even in extreme scenarios, such as a compromised Apple account or cloud breach.
How to set up passkeys on your Mac
Setting up passkeys is simple and requires iCloud Keychain to be enabled.
- Choose the Apple menu, then select System Settings.
- Click your name, then click iCloud.
- Click Passwords. In macOS Sonoma or earlier, click Passwords & Keychain.
- Click Sync this Mac, then click Done.
- When you sign up for a website or app that supports passkeys, you’ll now see the option to create a passkey.
- If your Mac has Touch ID, place your finger on the sensor to confirm.
- If you are using an iPhone or iPad nearby, select Other Options and scan the QR code shown on your Mac to confirm with Face ID.
- You can also replace an existing password by visiting the account settings of a supported website or app and selecting the option to switch to a passkey.
Once created, your passkeys are automatically stored in iCloud Keychain and available on all devices signed in with the same Apple ID.
Major services that support passkeys
Passkey adoption is growing quickly across major tech platforms. As of now, many of the biggest online services already let you sign in without a password.
Some of the key ones include:
- Microsoft
- Apple
- Amazon
- PayPal
- GitHub
- Uber
- eBay
Support for passkeys continues to expand every month as more companies integrate the technology into their login systems. On most of these platforms, you can now create new accounts or switch your existing ones to passkeys for faster, more secure sign-ins.

6 additional steps to keep your Mac safe
Passkeys add a strong layer of protection, but good security habits still matter. Here are more steps to strengthen your Mac’s defenses.
1) Enable two-factor authentication
Two-factor authentication (2FA) adds another layer of protection to your Apple ID. It works by requiring two forms of verification: your password and a one-time code sent to a trusted device or phone number. This means that even if someone somehow gets your password, they still cannot access your account without also having your device.

2) Review your trusted devices and numbers
Regularly check which devices and phone numbers are linked to your Apple ID. On your Mac, click the Apple icon in the upper left of the screen. Then go to System Settings → Apple ID → Devices and remove anything you don’t recognize. Make sure your trusted phone number is still current, since it’s critical for account recovery.
3) Use a password manager
Even though passkeys are replacing passwords, many sites still rely on traditional logins. A password manager helps you create, store and fill in unique passwords for every account. iCloud Keychain can do this automatically across all your Apple devices, but if you want more flexibility, you might want to consider a third-party password manager.
Next, see if your email has been exposed in past breaches. Our No. 1 password manager pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

4) Be wary of phishing attempts and install strong antivirus software
Phishing remains one of the most common ways attackers try to steal personal information. They may send fake emails or messages pretending to be from Apple or other trusted companies, urging you to click links or provide login details. Always double-check the sender’s address and avoid clicking on links that seem suspicious. Instead, visit the website directly by typing the address into your browser.
While macOS has strong built-in defenses such as Gatekeeper and XProtect, installing strong antivirus software adds another layer of protection against malware, adware and potentially unwanted programs. Strong antivirus software continuously monitors your system for suspicious behavior and can alert you to threats before they cause damage. It is especially useful if you download files from outside the App Store or connect external drives frequently.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

5) Turn On FileVault disk encryption
FileVault protects everything stored on your Mac by encrypting the entire hard drive. That means if your computer is ever lost or stolen, your data stays locked away from prying eyes. Go to System Settings → Privacy & Security → FileVault to enable it.
6) Keep macOS updated automatically
Apple regularly releases software updates that include important security patches. Cybercriminals often target outdated systems because they contain known vulnerabilities. By keeping macOS and your apps up to date, you make it harder for attackers to exploit weaknesses. To make this effortless, turn on Automatic Updates under System Settings → General → Software Update → Automatic Updates.
7) Back up with time machine
Backing up your Mac is just as important as protecting it. Time Machine automatically backs up your files to an external drive or network disk, keeping your data safe from ransomware, hardware failure or accidental deletion. Make sure your backup drive is encrypted for extra protection.

8) Use a data removal service
Even with passkeys, your personal information can still be exposed through data broker sites that collect and sell your details. Using a data removal service can help remove your private data from hundreds of these sites automatically. It’s an effective way to reduce your online footprint and protect your identity, especially when combined with Apple’s built-in security tools.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.
