Apple Releases macOS Sierra 10.12.4 and More with Security Fixes Posted on March 29th, 2017 by Apple this week released security software updates for all of its operating systems, Safari, Pages, Numbers and Keynote. As we all know, there is much more to these updates than what's shown in the update description, so here are some of the details. MacOS Sierra 10.12.4 Available for: Any Mac running macOS Sierra 10.12.3 Listed as an update that improves the stability, compatibility, and security of your Mac, it mentions the following as being new and improved:. Adds Night Shift for automatically shifting the colors in your display to the warmer end of the spectrum after dark. Adds Siri support for cricket scores, schedules, and player rosters from the Indian Premier League and International Cricket Council.
Adds Dictation support for Shanghainese. Improves right-to-left language support for the Touch Bar, toolbar, and visual tab picker in Safari. Resolves several PDF rendering and annotation issues in Preview. Improves the visibility of the subject line when using Conversation View in Mail.
Fixes an issue that may prevent content from appearing in Mail messages. Adds support for more. Night shift is available to all Macs from 2012 (Mac Pro not included) and newer. For those on older Macs, or even those on newer Macs, still offers superior controls and results.
Another new feature which was not mentioned by Apple is the option. The macOS Sierra 10.12.4 update also addresses a long list of security issues, 127 to be exact. This includes:. 22 fixes for memory corruption related issues that can lead to unexpected application termination, arbitrary code execution or both. 41 tcpdump issues that could lead to an attacker in a privileged network position may be able to execute arbitrary code with user assistance. 11 issues where processing a maliciously crafted image could lead to a denial of service, arbitrary code execution or unexpected application termination.
MacOS Sierra 10.12.4 includes an EFI firmware patch for some machines to address potential firmware attacks. According to Apple, 'A malicious Thunderbolt adapter may be able to recover the FileVault 2 encryption password.' Attacking the firmware to bypass security is not unheard of as the recent WikiLeaks dumped documents show that the CIA has been using such an exploit, called 'Sonic Screwdriver,' and the bug a few years ago that also found a way to modify firmware.
The firmware will automatically be patched when the macOS Sierra 10.12.4 update is installed. If you feel your hardware is at risk for having their firmware exploited through malicious Thunderbolt adapters, you may want to know that not all Macs had their firmware patched. Following are some of the Macs we know of that did not get their firmware updated: - iMac (27-inch, Mid 2011) - iMac (27-inch, Late 2012) - iMac (21.5-inch, Early 2013) - MacBook Pro (13/15/17-inch, Early 2011) - MacBook Pro (Retina, 15-inch, Late 2013) - MacBook Pro (Retina, 15-inch, Mid 2014) - Mac mini (Mid 2011) (with AMD Radeon Graphics) - Mac mini (Server, Mid 2011) - Mac mini (Server, Late 2012) - Mac mini (Late 2014) (Hat tip to for that list.) The above Macs are potentially still vulnerable to the EFI firmware vulnerability.
