You can stop holding your breath. Down the rabbit hole of neat, lesser-known Terminal commands is back! ICYMI, I’ve recently found myself fascinated by all the helpful tricks Terminal can do to improve my productivity and overall make me more proficient behind a Mac as a security practitioner. In previous editions, I covered everything from enabling Touch ID for sudo authentication to cleaning up public Wi-Fi connections. This week, I share even more commands I’ve since discovered.

Plastic webcam covers—especially of the sliding kind—boomed in popularity sometime in the 2010s as a low-tech way to keep hackers from eavesdropping on compromised machines. The concern felt justified at the time. But by 2020, Apple was beginning to issue warnings that those covers aren’t actually needed and can even damage a MacBook’s display.

For this Security Bite, let’s set the tin-foil hats aside and talk about why webcam covers don’t meaningfully improve privacy, can cause features like True Tone to not work properly, and are far more likely to damage your screen than stop someone from spying on you.

The wait is over. Our annual best new iPhone pro-model pictures roundup has concluded. After combing through the thousands of iPhone 17 Pro images submitted by the 9to5Mac community across a variety of social platforms, here were the standouts and arguably best we’ve seen yet.

Update, November 1, 10:59 a.m. ET: Apple has removed the sketchy ChatGPT clone app mentioned below. I’ve also received unverified claims that many other copycats have been taken down too.

Around this time two years ago, OpenAI’s incredibly popular GPT-4 API was spreading like wildfire all over the App Store. It wasn’t long before AI-powered productivity apps, chatbot companions, nutritional trackers, and basically anything else you could think of dominated the charts, garnering millions of downloads. Fast forward to today, many of those vibe-coded, opportunistic apps have disappeared, partly due to cooling hype but also Apple’s tougher stance against knockoffs and misleading apps.

However, this week, security researcher Alex Kleber noticed that one misleading AI chatbot, impersonating OpenAI’s branding, managed to achieve top marks in the Business category. Albeit on the less popular Mac App Store, this is still significant and warrants a brief PSA to be cautious when sharing personal information with these apps.

After teasing its release earlier this month, MacPaw, the macOS software company behind many beloved apps such as CleanMyMac and Setapp, has officially launched Moonlock today. It’s an all-new standalone cybersecurity application built to give you real-time protection, visibility into your Mac’s security posture, and provide clear steps to improve it, without overcomplicating things. The look, feel, and even sound design are exactly what you’d expect from MacPaw.

When Apple dropped App Tracking Transparency (ATT) prompts in iOS 14.5 back in 2021, it was a watershed moment for user privacy within third-party applications. Nothing like it had existed prior. The initiative gave iPhone users control over whether their in-app data could be aggregated and shared with third parties for advertising or other various purposes.

Still, today, I often find comments online from people who don’t really know what it does and find the wording very taboo. Like, why “Ask” the app? And is it still effective? Let’s briefly look at App Tracking Transparency in 2025…

Earlier this year, Apple announced that it was leading the charge on a cross-industry effort to bring end-to-end encryption (E2EE) to the RCS Universal Profile, which is published by the GSMA. Apple told 9to5Mac in March it would come to the iPhone in a future software update. Google soon after jumped in, stating it too was ‘committed to providing a secure messaging experience.’

I didn’t think it was completely unreasonable to assume we’d see this showcased at WWDC 2025…that didn’t happen. Then I thought maybe in one of the iOS 26 betas? Also nothing. So, what happened to cross-platform E2EE for RCS messaging? Is it still coming?

Earlier this month, Moonlock, the cybersecurity division of MacPaw, released its Mac Security Survey 2025. It surveyed nearly 2,000 macOS users about their habits, concerns, and overall perceptions of cybersecurity on Mac. Most notably, the findings reveal an interesting shift in how Mac users perceive malware and the overall strength of Apple’s defenses.

If you upgraded to iOS 26, you know the design changes and visual overhaul of Liquid Glass are undeniably impressive. But from a security perspective, one feature in particular has piqued my interest and seemingly gone under the radar: a new permission setting for wired accessories. This overlooked feature could be one of the most practical defenses Apple has shipped in years.

After warning 9to5Mac last month about undetectable Mac malware hidden in a fake PDF converter site, Mosyle, a leader in Apple device management and security, has now uncovered a new infostealer. Dubbed ModStealer, the malware has remained invisible to all major antivirus engines since first appearing on VirusTotal nearly a month ago.

In details shared exclusively with 9to5Mac, Mosyle says ModStealer doesn’t just target macOS systems, but is cross-platform and purpose-built for one thing: stealing data.

In an earlier edition of Security Bite, I predicted that Apple would finally announce end-to-end encryption (E2EE) to the RCS Universal Profile at WWDC 2025. That didn’t happen, but Apple did introduce two nice spam-protection tools along with a series of smaller updates designed to make the iPhone safer for everyone. Now that iOS 26 is basically in its final form ahead of wide release in tandem with the launch of iPhone 17, here’s a rundown of my favorite privacy features.

Malware has been a persistent threat since the first virus appeared in 1982 as a prank on Apple II computers. And malware is here to stay, but not because cybercriminals and nation-states are clever (they are), but because it’s mathematically impossible to stop it.

Mosyle, a leader in Apple device management and security, has exclusively revealed to 9to5Mac details on a new Mac malware strain, dubbed “JSCoreRunner”. The zero-day threat evaded all detections on VirusTotal at the time of discovery, spreading through a malicious PDF conversion site called fileripple[.]com to trick users into downloading what appears to be a harmless utility.

TikTok has been found selling GPS trackers through its Shop feature that are being marketed by viral videos explicitly encouraging secretly tracking a romantic partner. What’s most alarming is that these videos have millions of views, and metrics show that over a hundred thousand have been sold.

I usually reserve Security Bite for digital security topics, but this discovery was too riveting to ignore. As first reported by 404 Media, the trackers are being compared to Apple AirTags—but for the wrong reasons…

Since rising to prominence in 2023, AMOS (Atomic macOS Stealer) has become the most notorious infostealer targeting the Apple ecosystem. The malware, designed to quietly pull all sorts of sensitive information from macOS systems, is a household name among security researchers, journalists, and maybe even victims.

But now, Moonlock, the cybersecurity division of MacPaw, says it’s been tracking a new threat actor with an infostealer gaining popularity in the veiled corners of darknet forums. In this week’s Security Bite, I discuss this interesting new emerging threat and how it’s shaking up the broader macOS landscape.

The US-based security software firm Malwarebytes recently published a new study that attempts to settle the long-running iPhone vs. Android debate. This time, the focus isn’t on speed or camera quality, but on which users are safer online, including who takes more risks, who is less cautious, and who is more likely to fall for scams. The results are pretty surprising, but I think the real reason behind them has less to do with tech and more to do with behavior.

Let’s say you have screenshots of sensitive information sitting on your desktop that you’d like to password protect. You know that images of tax, banking, wire transfer forms, etc. in the clear can easily be viewed by anyone with physical or remote access to your machine, but you’re unsure how to secure them. Unfortunately, macOS Preview doesn’t support file-level password protection, but there are quick workarounds that don’t require third-party software or downloading anything not already on your .

It’s the same early-day digital scareware we’ve all seen before: “Your iPhone is infected with (310) viruses. Click here to remove them.” These pop-ups, seemingly always 280p quality and slapped together with stock graphics from a different reality, usually appear on shady websites as malicious ads or junk software, urging people to install a “fix” or be doomed. But one was recently spotted running as an ad on YouTube for a sketchy iPhone clean up app.
