macOS Golden Gate 27.2 overhauls the brightness and volume sliders<\/a>, plus it expands Siri AI to new languages including French, Japanese, Korean, Portuguese, and Spanish.<\/p>\n<\/blockquote>\n\n

Apple just broke the macOS security update record AGAIN, patching 263 CVEs in macOS Golden Gate 27.2! 🤯🔐<\/p>\n<\/blockquote>\n\n

I decided to email Apple Product Security yesterday just to ask whether CVE-2026-112500 was my [e-mail privacy] issue. In the past I’ve had a number of email conversations with Apple Product Security, including a long-running thread initiated by them way back in 2024 about a WebKit security issue that I had reported, with last reply in July of this year. Sadly, as far as I can tell, I still haven’t been credit for that issue.<\/p>\n

[…]<\/p>\n

In other words, Apple Product Security no longer accepts reports via email, instead requiring security researchers to submit via a web form. But the web form wants you to “Report a vulnerability,” with no place for a simple question like mine, about a vulnerability already fixed. Also, the quoted paragraph implies that if you don’t use the web form, you might not get a CVE, which I suspect is what happened to me!<\/p>\n<\/blockquote>\n\n

PSA: If you use the removemacai tool and are having trouble updating to macOS 27.2, remove the RemoveMacAI profile in System Settings -> General -> Device Management. It appears to somehow block softwareupdate’s ability to download parts of the update.<\/p>\n<\/blockquote>\n\n

macOS 27.2 beta brings back the solid divider line between sidebars and their details view.<\/p>\n<\/blockquote>\n\n

\n

macOS 27.2 has reverted the [Mission Control] change: fullscreen apps are now once again titled by app name, not window title<\/p>\n<\/blockquote>\n\n

Still broken on macOS 27.2. No response to my Feedback so far.<\/p>\n

I’ve since added a workaround in Radiccio that simply removes the Liquid Glass effect (so the buttons can work again). <\/p>\n<\/blockquote>\n\n

Upgrading to macOS 27 no longer removes an existing Rosetta installation[…]<\/p>\n<\/blockquote>\n\n

Jeff Johnson<\/a>:<\/p>\n

\n

I suspect what Apple really meant is that macOS 27 was not automatically reinstalling Rosetta, and now it does again in 27.2.<\/p>\n<\/blockquote>\n\n
