macOS security updates - welcome to the "Slow Zone"


Speed limit's changed.

Changed again!

macOS Catalina is shipping late (relative to the iOS and iPad OS releases...). How late? The OS update for 2019 transition is already out;

macOS Mojave 10.14.6 Supplemental Update 2, Security Update 2019-005 High Sierra, Security Update 2019-005 Sierra

(Note that Sierra has already been dropped from this security update).



Historically Apple has provided security updates for the current-and-previous-two macOS versions.

For example, Safari 12 says "macOS Sierra 10.12.6, macOS High Sierra 10.13.6, and macOS Mojave 10.14".

They have been doing this since "19 Sept 2012", in when Mountain Lion received its first update. (OS X Mountain Lion v10.8.2, OS X Lion v10.7.5 and Security Update 2012-004)

Where is the Security Update for macOS?!

Somehow, over the years, I had not noticed that the date of a macOS release is earlier than the security update to the other "current" releases.

Updated -> Oct 30, 2018

macOS Mojave 10.14.1, Security Update 2018-002 High Sierra, Security Update 2018-005 Sierra macOS Sierra 10.12.6, macOS High Sierra 10.13.6, macOS Mojave 10.14 30 Oct 2018

Here's the current top of page (Sept 27, 2018)

Release date

macOS Mojave 10.14 MacBook (Early 2015 and later), MacBook Air (Mid 2012 and later), MacBook Pro (Mid 2012 and later), Mac mini (Late 2012 and later), iMac (Late 2012 and later), iMac Pro (all models), Mac Pro (Late 2013, Mid 2010, and Mid 2012 models with recommended Metal-capable graphics processor, including MSI Gaming Radeon RX 560 and Sapphire Radeon PULSE RX 580) 24 Sep 2018


Looking back a bit, it seems that High Sierra had the same delay. That is only partially comforting to me, I don't see why they can't just declare this as the policy or release strategy.

El Capitan users expected to be dropped with Mojave, but there are a lot of Sierra and High Sierra users that are left wondering if Safari 12 (alone) is enough to keep them current and safe.
