macOS 10.14.3 Update can't be installed on this disk...

Well I have found out why the Combo won't install.

There is an error in the distribution file, as part of the installation the distribution file runs a number of checks to determine if the update can be installed. One of these is the Volume check, so it checks the build number of your install of MacOS Mojave.

In the distribution file there is a list or array of the previous builds of the OS. The array in this Combo is very short so quite a few build numbers are missing and therefore the error is generated.

You could expand the 10.14.3Combo.pkg, using pkgutil in Terminal, edit the distribution file to include the build number of your install of Mojave, then use pkgutil to revert the expanded folder to a new .pkg and it should install. I did and it was successful.

Or you could wait until Apple sorts it out. Or just use software update.

Crikey.

Welp, 2 days later and Apple still hasn't fixed it.. Thank god I found this thread, I didn't even get notified by Software Update that it was out, I just saw it on an audio forum this morning and grabbed the combo heh. Anyways, 2010 Mac Pro running 10.14.2 here, same issue with the Combo Update. Wasn't sure if it was because SIP is disabled, or if Apple decided to pull the plug on us that went and bought PC Radeons to upgrade (who also have to use third party kexts just to get HDMI audio working again) or what.. Downloaded the Delta and it went fine.

Now to make sure Logic and my firewire audio interface still work!

Hi.

I was able to update my daughter's Macbook Air to version 10.14.3 using the Terminal command and giving the command below:

sudo softwareupdate --install --all --restart

Please open the Terminal command window and enter the above command. After following the on-screen instructions, the command will find all available updates and install them. After installation, your comp will restart.

Hope this helps.

System Preferences> Software Update only works if your Mac is running Mojave on an SSD formatted as APFS.

If you are already on 10.14.2 you can update to 10.14.3 by using the Delta update.

Download macOS Mojave 10.14.3 Update

William - in short:

The glib answer is about 0.5GB :o) - but it seems to be:

(10.14.0 or 10.14.1) to 10.14.3 - use Combo Updater;

10.14.2 to 10.14.3 - use Updater

And this definitely represents a change from how it used to be. Again - not sure if this was really Apple's intention or not - but that's certainly how it is at the moment ...

Hi there!

I experienced this Mojave 10.14.3 Combo Update issue on a MacBook Pro Late 2017.

Then I went on updating thru Software update.

The Combo update then works later on.

This corroborates the previous post by "Eau Rouge" on a bid number error in the current Combo distribution file.

Best!

My daughter's Macbook Air (Early 2015) has the same problem. She can't install the combo update.

Instead, I told her to use the Terminal with the command sudo softwareupdate -i -r

Now the update downloaded and installing. It is still in progress. So I can't tell if the update will be successful.

I will advise here if the update fails. No news means the method is successful.

Had same issue here with the Combo Update on my late 2013 27" iMac. It was downloaded

just a few moments ago so nothing has changed. Using SW Update now. See what happens.

The SW update just finished, but something odd happened. All times in the past, any macOS

update rebooted to the log in. This time it rebooted right to my user account. Seemed odd.

And no, log in is not disabled.

I have the same problem with the 10.14.3 combo update, for me the problem did not start with Mojave or this update.

Since installing Mac OS High Sierra I have not been able to install any system updates.

The incremental system updates download fine from the App store then I press restart. The computer changes to the black screen with the white Apple and the the message installing update, the progress bar does not move, after a couple of minutes the Macbook restarts without installing the update and leaving a folder named macOS Install Data on my hard drive.

For every update I have tried the following:

- Restarting in Safe Mode to install.

- Reseting the NVRAM and the SMC.

- Reinstalling Mac OS from recovery partition and internet recover.

- Downloading combo updates.

- Running Disk First Aid from recovery partition.

- Enabling Root User to install.

Non of these actions have resolve the issue. The only method I have found to work is downloading the combo update on another Mac and then installing it on the Macbook Prom using target disk mode.

By the way I have this issue on two computers, an iMac 27 and a Macbook Pro, both are formatted as APFS drives.

Hi.

I was able to install the update over Mojave 10.14.2 on my Macbook Air ( Early 2015 ) using the Terminal utility in

Applications\Utilities folder by running the command

sudo softwareupdate -i -r

Hope this helps.

Have you tried using Software Update since the combo update is failing?

Dick. What type of disk (HDD/SSD) are you using and how is it formatted (HFS+/APFS)?

Try downloading the update: Download macOS Mojave 10.14.3 Update

If you are running security software, try updating in Safe Mode.

Use safe mode to isolate issues with your Mac - Apple Support

Software Update does not work with HDs using HFS+

I have Mojave on SSD APFS, gets software updates, and Mojave on HD with HFS+ and software update never receives

update notifications.

The Combo and Delta updates do not install on HDs with HFS+, even though the full installers are able to install on both.

I just tend to think of Fusion drives as SSDs.

Because if you are running Mojave on an HD with HFS+, it would be reasonable to expect that you can update it.

Once again, since the Mojave installer will convert boot drives to APFS as part of the install, you’ve created an unsupported configuration if you somehow do have Mojave running on an HFS+ drive.
