Tired of hearing about DeepSeek yet? The China-based LLM chatbot beached itself onto the scene this week, dominating the tech news cycle and even taking #1 on the App Store, where it still sits as of writing. However, its rapid popularity has led to a wave of new phishing campaigns, investment scams, and macOS malware disguised as real DeepSeek applications. Here’s the latest.

Apple recently introduced Genmoji with iOS 18.2, which lets iPhone and iPad users create their own emoji using Apple Intelligence. Although the feature wasn’t included in the macOS 15.2 update, Genmoji is now available on the Mac with the first beta of macOS Sequoia 15.3.

Continuity is one of the biggest strengths of the Apple ecosystem, and iPhone Mirroring is a great addition to that – letting us not only mirror our iPhone to our Mac desktop, but also take full control of it.

I’m a huge fan of the feature, and use it every single day, but it does have a few weaknesses that I’d love to see Apple address …

Apple regularly lists resolved vulnerabilities for iPhone, iPad, and Mac after each software update. Right on cue, the company has released an extensive list of which security resolutions are included in today’s iOS 18.2 and macOS Sequoia 15.2 software updates.

Last week, I received an interesting report from the security research arm of the popular Apple device management software firm Jamf that detailed a serious but now-patched iOS and macOS vulnerability. The finding was under embargo, but today, I can finally talk about it.

Jamf Threat Labs uncovered a significant vulnerability in Apple’s iOS Transparency, Consent, and Control (TCC) subsystem on iOS and macOS that could allow malicious apps to access sensitive user data completely unnoticed without triggering any notifications or user consent prompts.

We’ve all heard the term the Walled Garden when talking about the Apple ecosystem. Apple’s biggest competitive advantage is the fact that they control everything from both a hardware and software perspective, allowing its customers to experience these little features I like to call Magic Moments. These are smaller utilities or features that are only possible because you have multiple Apple products that work off of each other giving us these wow moments. So here are some of my favorite Magic moments of the Apple Walled Garden.

In possibly a first since the release of macOS Sequoia, cybersecurity researchers have identified a new attack vector that sidesteps the usual “right-click, open” in favor of something rather unusual. In a recent finding shared on social media, this new method involves tricking users into dragging and dropping malicious code (via a .txt file) directly into the Terminal.

One of the new features of iOS 18 and macOS Sequoia is iPhone Mirroring – but using this with a personal iPhone on a work Mac currently creates a privacy risk for employees, and a legal risk for businesses.

The problem, as cybersecurity company Sevco discovered, is that apps on the iPhone get treated as Mac apps, and that means their presence is included in corporate IT audits …

With today’s release of macOS Sequoia 15.1 beta 6, Apple is making another change to screen recording permissions. The company says that this should mean users see fewer permission dialog popups on their Macs…

macOS 15.0.1 is now rolling out with some key bug fixes for Mac users. The update addresses problems in the Messages app as well as compatibility issues that had affected third-party security software. Head below for the full release notes.

macOS Sequoia screen recording permission reminders can now be permanently vanquished, thanks to a new pay-what-you-like app.

Apple’s new security feature was intended to make Macs safer, by reminding us that we’d granted a powerful and potentially dangerous permission to an app, but many experienced users simply found it irritating …

On Monday, Apple released its latest iteration of Mac’s operating system, macOS Sequoia. The new update introduced tighter control over app permissions and an overhaul to Gatekeeper, among other features. However, according to TechCrunch, it now appears to be disrupting security tools made by CrowdStrike, SentinelOne, and Microsoft. Social media users are also reporting connection failures with third-party VPNs.

Update (10/2): Thursday’s release of macOS 15.0.1 fixes the underlying networking issues that plagued certain security software in the initial release of macOS 15.

If you’re still running an Intel-powered Mac, you’ll have at least one more year of macOS support. macOS Sequoia runs on the same Macs as macOS Sonoma, but as usual, there are some caveats about specific features supported on Intel machines.

Now that macOS Sequoia is available to everyone, here’s what you need to know.

As promised last week, Apple today released macOS Sequoia to the public. The company had been running tests with beta versions of macOS 15 since June, when it was announced at WWDC. The next version of the macOS operating system brings new features such as iPhone Mirroring and a Passwords app.

At today’s “It’s Glowtime” Apple Event, the company has announced that macOS Sequoia will be released on September 16th. Apple announced macOS Sequoia at WWDC24 back in June, with new features such as window tiling, iPhone Mirroring, and more.
