Where can I get a complete Sequoia 15.4 installer?

You can see if running…

softwareupdate --fetch-full-installer --full-installer-version 15.4

in the Terminal works.

Thanks. It's not in the Applications folder yet. I assume it will only appear when it is completely downloaded?

I see that PRP used a different command to reveal the installers.

As you can guess my knowledge of Terminal is little better than zero.

Yes, different in that it only looks for ( Lists ) the available full versions

softwareupdate --list-full-installers

Had I been on the M2 machine it may have listed Ventura, Sonoma and Sequoia

What are your results ?

Does it find 15.4 ?

softwareupdate --list-full-installers

Finding available software

Software Update found the following full installers:

* Title: macOS Sequoia, Version: 15.4, Size: 15243957KiB, Build: 24E248

* Title: macOS Sequoia, Version: 15.3.2, Size: 14890483KiB, Build: 24D8

* Title: macOS Sequoia, Version: 15.3.1, Size: 14891477KiB, Build: 24D70

* Title: macOS Sequoia, Version: 15.3, Size: 14889290KiB, Build: 24D60

* Title: macOS Sequoia, Version: 15.2, Size: 14921025KiB, Build: 24C101

Apple rarely puts out a full installer version when the update is released. It may take a few days if they release one at all.

Seems that there is a listing for the full installer, but it doesn’t download. It may be related to the fact that the Beta version is still listed and has the same version number.

Waiting is likely the only solution.

Thursday, the day after sort of speak

This is a Purported Terminal Solution from another similar issue

Unable to install macOS Sequoia update 15… - Apple Community

It would appear on page 2 of that question

I have not personally attempted that terminal command nor do I Know if it will work

Good Luck 🤞

Success at last.

Today the App Store (UK) had Sequoia 15.4

Good things come to those who wait.

In my case it found 15.4 and others within about 3 to 3.5 seconds

Just re=tested before this reply

Running over a Fibre Optic connection with 500 / 500 speeds

Perhaps if you what to Test this again

The Old Safe Boot thing and run the command again ?

74.0% of 100% should good

Just another 26 % to go 👍

As previously mentioned the Full Version should appear in Applications folder

" Install Sequoia app " and yes it will not automatically launch

Happy updating the Fleet of machines

An aside, sometimes I do exactly has you are doing for Multi M Class computers, but not this time

@ Ian R. Brown

OUCH

Let me try the softwareupdate --fetch-full-installer --full-installer-version 15.4 "

softwareupdate --fetch-full-installer --full-installer-version 15.4

Scanning for 15.4 installer

Install failed with error: Update not found 

Guess work - Apple is having a Server issue

In your case @ 90% downloaded and 10% more to come

Abort

I don't believe this is an Apple server problem. I get the same message (Install failed with error: Update not found) when trying to download the full 15.4 installer (or any full installer in the list of available ones in fact) using softwareupdate from the command line on a Mac with 15.4 already installed.

I have a second Mac for work that is still on 15.3.2 and the same software update command downloads the 15.4 installer successfully.

It seems there is something about 15.4 that leads to this "Update not found" error when using software update to download an installer for any version of macOS, including 15.4.

Good idea

Yes others are experiencing this issue

Yes my test download earlier was from an already success update via the Software Update applet

Do not know factually if there is a correlation but seems reasonable to believe it so, for now 😔
