Apple has released MacOS 10.14.2 update for MacOS Mojave. The latest software update for the Mac is said to improve the stability, compatibility, and security of Macs, and is therefore recommended for all Mojave users to install.

Mac users not running Mojave will instead find “Security Update 2018-003 High Sierra” and “Security Update 2018-006 Sierra” available for prior MacOS versions, along with updates to the Safari web browser.

Separately, Apple also released iOS 12.1.1 update for iPhone and iPad, along with an update to tvOS for Apple TV, an update for Homepod, and a small update to iTunes for Windows, along with watchOS 5.1.2 for Apple Watch with ECG and health features.

How to Update to MacOS 10.14.2

Be sure to backup the Mac before installing any system software update, backing up with Time Machine is easy and strongly recommended.

Recall that updating macOS system software is now done through the Software Update control panel in MacOS 10.14 onward, thus to install macOS 10.14.2:

Go to the  Apple menu and choose “System Preferences” Select the “Software Update” control panel When ‘macOS 10.14.2 Update’ shows as available, click on “Update Now”

The update to Mojave is over 2 GB, and the Mac will reboot to complete the installation of macOS 10.14.2. Installing the update can take longer than expected in some cases, so be patient.

Earlier versions of MacOS prior to Mojave will instead find “Security Update 2018-003 High Sierra” and “Security Update 2018-006 Sierra” available from the Mac App Store “Updates” section.

Separately, Mac users can also choose to download the MacOS 10.14.2 update directly from Apple, either as a standard update or as a combo update, or download the security updates for Sierra and High Sierra.

Most Mac users should simply update through the Software Update mechanisms on their Macs, though using a Combo Update with Mac OS is helpful if you’re updating from an earlier version of Mojave (eg from 10.14 directly to 10.14.2, skipping the .1 release), and running the combo update can also be helpful for troubleshooting a failed MacOS software update process.

MacOS 10.14.2 Release Notes

Release notes accompanying the MacOS Mojave 10.14.2 update download are brief:

MacOS Mojave 10.14.2 update improves the stability, compatibility, and security of your Mac, and is recommended for all users. This update: – Adds RTT support for Wi-Fi Calling – Adds a menu item to News for opening a story in Safari – Resolves an issue that may precent iTunes from playing media to third-party AirPlay speakers

Presumably a wide variety of bugs and other issues have been addressed, even if they’re not specified in the release notes.

It’s possible that 10.14.2 may help with some user reported difficulties that are not mentioned in the release notes, for example some reports of battery drain, or wi-fi issues with MacOS Mojave, though for most users any wi-fi problems are easily resolved by setting up new network locations after removing old preference files, a process which is entirely separate from software updates. Nonetheless it’s good practice to install system software updates when available.

Separately, Apple also released iOS 12.1.1 update for iPhone and iPad along with an update to tvOS for Apple TV, and to HomePod.
