Key fixes include multiple kernel memory corruption and use-after-free issues, privilege escalation bugs in Accounts, CUPS, Remote Management, and SecurityAgent, sandbox escapes in Audio, Game Center, Maps, and libc, arbitrary code execution vulnerabilities in HFS, ImageIO, SceneKit, and Wi-Fi, and numerous WebKit flaws including use-after-free crashes and iframe sandboxing bypasses. Third-party open source components such as Apache, curl, and libarchive also received patches. Researchers from organizations including STAR Labs, Blackwing Intelligence, Cisco Talos, and ThreatBook are credited. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Community take How the wider developer community reacted, aggregated from 1 discussion and 133 comments across hackernews (as of 2026-07-28). **TL;DR:** The community is largely critical of macOS 26 (Tahoe), especially its Liquid Glass UI, high CVE count, and instability, though there is cautious optimism that macOS 27 addresses many of the worst issues. The sheer volume of security fixes and AI-assisted CVE discovery are also notable talking points. **Sentiment:** 10% positive · 40% mixed · 50% skeptical **The case for** - macOS 27 beta reportedly fixes the most egregious Liquid Glass issues, including oversized corner radii and icon spam in menus. - macOS 27 betas are generally reported as faster than macOS 26. - Liquid Glass effects can largely be disabled via Accessibility > Reduce Transparency in macOS 26. - AI-assisted vulnerability discovery (Claude/Anthropic credited) is accelerating security research. **The pushback** - macOS 26 (Tahoe) is widely criticized for its Liquid Glass UI, described as 'comically bad' and 'Fisher-Price'-like. - The record-breaking CVE count (~155) for a single release raises serious concerns about Apple's software quality. - Even 'minor' security updates have broken CI/CD and other workflows, making any update risky. - Intel Mac users are stuck on broken macOS 26 with no path to macOS 27. - AI features are being pushed intrusively into core workflows (e.g., camera app blocking photo saves). - Apple's CVE descriptions remain vague, limiting users' ability to assess actual risk. **By community** - hackernews (skeptical): Commenters are broadly critical of macOS 26's UI and stability, cautiously optimistic about macOS 27, and concerned about the record number of CVEs and the implications of AI-accelerated vulnerability discovery. **Hottest debate:** Whether it is safe or advisable to install Apple's 'minor' security updates given their history of breaking existing workflows. **Open questions** - Will macOS 27 be a sufficient improvement over macOS 15 to justify tolerating any remaining Liquid Glass elements? - How much of the record CVE count is attributable to AI-assisted discovery versus genuinely worsening software quality? - Will Apple ever provide more detailed CVE descriptions to help users assess risk? - What will happen to users on Intel Macs permanently stuck on the buggy macOS 26? **Highlights** > > AI stuff they're starting to push through iOS 26 anecdote: A couple of weeks ago, I had a Baltimore Oriole (a cool-looking bird, not a baseball player) in my yard. They aren't rare, per se, but they are uncommon. Took my iPhone out to snap a picture, and pressed the camera button. I hadn't used it, since upgrading to 26. It takes the picture. It's there. I can see it, but it won't let me save it. Instead, it wants to tell me about the cool new voice-activated AI retouch feature. There was no way to save. I probably could have figured it out, but I was so furious, I just nuked the picture. > — [ChrisMarshallNY on hackernews](https://news.ycombinator.com/item?id=49085001) > You can already turn off most glass effects in 26 via "System Settings => Accessibility => Display => Reduce Transparency". I had that turned off years ago (for reasons I don't remember), and was wondering what all the fuzz was about when 26 came out because I didn't see much of a difference ;) IMHO the actual important visual changes in the 27 beta is that rolls back the bizarre oversized corner radius in Finder windows, and they also got rid of the 'every menu item must have an icon' idea. > — [flohofwoe on hackernews · 2 comments](https://news.ycombinator.com/item?id=49082998) > That's the sad thing: Apple decided to leave all Intel macs on broken macOS 26. Very bad on Apple's part. > — [reddalo on hackernews](https://news.ycombinator.com/item?id=49083931) > It is a lot of fixes and the Android Security Bulletins of June and Android 17 also had a lot of fixes [1], despite ASBs only containing high/critical vulnerabilities (other vulnerabilities are only fixed in major releases and QPRs, which most Android vendors respectively roll out late or never at all). I think the story here is that vulnerability discovery has accelerated a lot with LLMs, but since are adversaries are doing the same, it is more important than ever to update quickly (and not let some Android vendors get away with their lazy update schedules).

I figured it's so obviously bad that it was just sloppy work. But one of the WWDC session videos bafflingly clarified that it depends on whether the app has a toolbar or not. https://youtu.be/VqTn9NgiE1s?t=439 I can't imagine how the people who signed off on that were put in charge of design at Apple. > — [hbn on hackernews · 1 comments](https://news.ycombinator.com/item?id=49084048) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=49081555) · 75 points · 133 comments ## Community discussion Top comments from developers on daily.dev. **@tokstesla** · 0 upvotes > the privilege escalation bugs are the real nuts for me **@ruhabasim** · 0 upvotes > That's one long security changelog > >  ## Similar posts on daily.dev - [macOS Tahoe 26.2 Release Notes](https://daily.dev/posts/macos-tahoe-26-2-release-notes-r0coe82sh) · Hacker News · 0 upvotes · 0 comments - [Apple patches CoreGraphics zero-day flaw exploited in attacks](https://daily.dev/posts/apple-patches-coregraphics-zero-day-flaw-exploited-in-attacks-0ov4mhz7v) · BleepingComputer · 2 upvotes · 0 comments - [Still running iOS 26?
