“To monitor a target, a government operator of Pegasus must convince the target to click on a specially crafted exploit link, which, when clicked, delivers a chain of zero-day exploits to penetrate security features on the phone and installs Pegasus without the user’s knowledge or permission. This vulnerability allowed NSO Group’s customer to insinuate “Pegasus” onto a target phone, as reported by CitizenLab:

If folks make enough noise, maybe this can get corrected and Apple will continue releasing full installers (and IPSWs) for all Big Sur security updates (and future versions) before it becomes accepted for them not to release anything after the last non-security update.Īs Howard noted on his Twitter feed yesterday (9/17/21) there is a dive into Pegasus (or rather, Apple’s patch to the vulnerability exploited by Pegasus) on Patrick Wardell’s site by guest author Tom McGuire: It’s like Apple settled on the least consistent and the worst of both platforms. This would have been a change, but it would have filled the void of the lack of standalone installers for Security Updates.īut now 11.6 is not even available as an IPSW for Apple Silicon while iOS 14.8 is, and we are also left high and dry with no full installer or standalone updater for Security Updates. The most hopeful, obvious, and consistent thing to expect would have been that we would just continue getting full installers with Security Updates included (like iOS does). Over the course of Big Sur, we got used to this change and accepted that we would get full installers instead of standalone updaters, while knowing full well that the future of Security Updates was unknown and possibly different from (or the same as) the past.

It seemed that Apple was bringing all this behavior in sync across iOS and macOS with the new version numbering as well as the new updating system on macOS, which is now uses the same update framework as iOS (which seems to be why standalone pkg updaters are no longer available, since that was part of the legacy update system). So if you restore an iPhone through iTunes/Finder/Apple Configurator 2, you always get the latest fully patched version.

The behavior of having to do a clean install of an unpatched version such as 10.15.7 (19H15) or 10.14.6 (18G103) and then installing the latest Security Updates separately has been the (unfortunate, stupid) norm on macOS.īut on the iOS/iPadOS side of things, security updates have always been released as full IPSW firmware.
Yeah, it feels like Apple is trying to be consistent with iOS on one hand and holding firmly to past macOS standards with the other.
Thanks to Pico for passing the link to the standalone Catalina updater.

To ensure that your Mac has the new update to MRT, once it has completed the macOS update, you should run SilentKnight to download and install MRT 1.84. The version of MRT installed by the 11.6 update is 1.81. It’s also possible that, as Big Sur enters its two-year maintenance period, Apple intends releasing security updates as 11.6.1 et seq.Ĭongratulations to Mikey who has worked out that the PDF vulnerability is most probably the same as the Megalodon/FORCEDENTRY iMessage zero click exploit, involving a bug in CoreGraphics decoding JBIG2-encoded data in a PDF file. There’s no information about any changes other than these important security updates, and widespread opinion that this Big Sur update should be considered a minor security patch, and perhaps better as version 11.5.3 rather than a ‘full’ minor update. Apple doesn’t provide any standalone updates for Big Sur, though.įull details of the security fixes are available here. Apple doesn’t disclose what changes that brings.īig Sur 11.6 update is around 2.64 GB for Intel Macs, and just over 3.5 GB for M1 Macs.Ĭatalina Security Update 2021-005 is 1.45 GB, and a standalone updater for it is now available from here. In addition, a new version of MRT is available, bringing it to 1.84. There doesn’t appear to be any Security Update for Mojave, though, suggesting that it has now reached the end of its support.
The first of those is also fixed in Catalina Security Update 2021-005. MacOS 11.6 fixes two serious vulnerabilities, one of which is being actively exploited in crafted PDF files, the other being actively exploited in crafted web content. Apple has just released three important updates: Big Sur 11.6, Catalina Security Update 2021-005, and MRT 1.84.
