Jan 22, 2019 - 21 Comments

New macOS Mojave software update

Apple has released MacOS Mojave 10.14.3 for Mac users running the latest operating system. The new release includes bug fixes and security enhancements and is therefore recommended to MacOS Mojave users.

Mac users running prior MacOS releases of High Sierra and Sierra will find security updates available in the Mac App Store as well, labeled as Security Update 2019-001 10.13.6 and Security Update 2019-001 10.12.6 respectively, along with an update to Safari.

Additionally, Apple has also released software updates for Apple Watch, Apple TV, HomePod, and iPhone and iPad. Users can download iOS 12.1.3 update for iPhone and iPad along with the watchOS and tvOS updates from the Settings apps on those devices.

How to Update to MacOS Mojave 10.14.3

Always backup a Mac before installing any system software update, backing up with Time Machine is easy. Remember that MacOS Mojave has changed how to install MacOS system software updates, moving the update functionality back to the System Preferences away from the App Store.

  1. Choose the  Apple menu and select “System Preferences”
  2. Choose the “Software Update” control panel
  3. When ‘macOS 10.14.3 Update’ shows as available, click on “Update Now”

    I spent most of the day today trying (twice) to install 10.14.3 on top of High Sierra. Both times, 20 minutes from being completed, iMac went into an endless loop. Only recourse was to rebuild disk from Time Machine, an excruciating four-hour process. Guess I’ll just stick with High Sierra. Mojave isn’t worth the effort and heartbreak and gnashing of teeth! I can’t believe Apple actually released this. I thought surely by .3, we’d have a smoothly operating system. Cook definitely did NOT earn his performance bonus this time around!

    Hi,

    I am in the process of installing Mojave on my MacPro 2013 again as it is not doing what I would like it to do.

    In previous versions, I’ll boot from an USB, format the internal hard drive with FileVault encryption, install and complete the setup with a user account. This allows me to have full disk encryption with one password and another password for the user account.

    Unfortunately, in Mojave, I went through the same process but once installed, it would boot into my user account and not allowing me to enter my FileVault password. The system said that FileVault is on.

    Can you let me know how I can full disk encrypt with one password and another for a user account?

    Thanks

    I was going to do this update but after reading some opinion I hesitate to do it

    My iMac now wouldn’t win a race against a snail…

    Come on Apple, sort this mess out!

    Feels Snappier

    My iMac became uber slow in booting up and not detecting my mouse (Logitech G903) upon reaching the desktop – after this update.

    Now looking for my Time Machine drive…

  8. Yeah That Dude says:

    The update really messed up iMessage. Take like 15seconds now fter opening to use.

  9. Cuppa says:

    Other sites suggest there is a bug in the 10.14.3 combo distribution file where it fails to list all the builds of 10.14. Result is ‘cannot install on this disk’. Annoying when you have dowloaded almost 2.5 Gb of combo update via a slow cell phone connection with a limited monthly data limit. Apparently the update via Sys prefs works ok, & you can even then install the combo update over that if you really want to.

  10. djpenn says:

    If you look at the 10.14.2 Combo Update it is 2.52 GB in size while the 10.14.3 CU is 2.49 GB in size. I suspect that is why the 10.14.3 CU will not work on 10.14.2 — you’d basically be adding code only to immediately rip it out, which is inefficient.

    But Apple should have listed this caveat at https://support.apple.com/kb/DL1992

  11. Andrea says:

    Downloaded the Combo Update and, yes, it will not install over 10.14.2.
    Quite weird…
    Will try to download the mere 10.14.3 update, tomorrow.

  12. Steve says:

    The Combo Update will not install on a system with 10.14.2 installed. The 10.14.3 Update installed just fine.

  13. lica says:

    sry but i fail to see any value in this article. Aside from pointing at the update, that it’s there and how you can install it, no other details about what this update is actually doing, and if it should be done or kept away, if it breaks anything (that would of been more helpful).

    Can’t install this update. Not showing up on Software Update prefpane either. :/
