Hello everyone,

I wanted to create a USB Ventura 13.4.1 iso installer, by downloading macOS 13.4.1, using Terminal.

Therefore, since the previous version of Ventura, which is 13.4, was installed on a separate APFS Volume.

I tried using both of these Terminal commands:
softwareupdate --fetch-full-installer --full-installer-version 13.4.1
softwareupdate --fetch-full-installer

Terminal showed these results:

For the command, softwareupdate --fetch-full-installer --full-installer-version 13.4.1, Terminal showed:
Last login: Sat Jul 8 02:51:10 on console
p@ps-MacBook-Pro ~ % softwareupdate --fetch-full-installer --full-installer-version 13.4.1
Scanning for 13.4.1 installer
Scanning for installer
Install finished successfully
p@ps-MacBook-Pro ~ %

But there was no installer anywhere on my Mac.

So I then tried using softwareupdate --fetch-full-installer.
At the end of the fetch-full-installer download, Terminal showed:
Last login: Fri Jul 7 0218:02:30 on ttys000
p@ps-MacBook-Pro ~ % softwareupdate --fetch-full-installer
Scanning for installer
Install finished successfully
p@ps-MacBook-Pro ~ %

But there was no installer anywhere on my Mac.

Anyone know of a fix that will make downloading Ventura 13.4.1 iso, using Terminal, work?

Hi bogdanw,

But both of those links,
That only downloads Install macOS Ventura 13.4.1.

But what I need is: Ventura 13.4.1 ISO

Apple does not provide ISO files. Why do you need an ISO file? You can create one if necessary.

I don’t really understand what you are trying to do, but here is how to create a Ventura ISO from the Install macOS Ventura.app

Code: 
hdiutil create ~/Desktop/13.dmg -size 20g -layout SPUD -fs HFS+J

hdiutil attach ~/Desktop/13.dmg -noverify -nobrowse -mountpoint /Volumes/InstallVentura

sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/InstallVentura

hdiutil detach /Volumes/Install\ macOS\ Ventura

hdiutil resize -sectors min ~/Desktop/13.dmg

hdiutil convert ~/Desktop/13.dmg -format UDTO -o ~/Desktop/13.cdr

mv ~/Desktop/13.cdr ~/Desktop/13.iso

If you have 13.dmg, 13.cdr or 13.iso files on your desktop delete them (from Trash too), reboot and try from the start. Wait for each command to finish successfully before running another one.

If one command fails, don't run the subsequent ones, it's pointless.
After a failed attempt, delete the 13.dmg file created by the first command on your Desktop.
Ensure that you have enough free space on the drive, you need at least 50GB.

Hi bogdanw,

Regarding the size requirement, there is 663 GB available.

You can try with gibMacOS

Using this script you can select desired macOS version and download it.

I use this script whenever I need an older macOS release

Are you trying to make a bootable USB? Or are you trying to make an ISO from a bootable macOS install drive to then present to a Windows guest OS as a mounted disk?

If the former:

...then you're over-complicating this by a ton. Just:

(a) download the lastest version of the "Install macOS Ventura" app either from the App Store/Software Update function, from Mr.Macintosh's Site (which links to Apple's CDN), or using the softwareupdate command with the fetchfullinstaller option (though, I find that the softwareupdate command can be hit and miss with this; Apple keeps doing things to break it on their end.

and then

(b) Run the createinstallmedia command from within the downloaded "Install macOS Ventura" app while targeting an empty GPT-schemed macOS Extended (Journaled) volume

If the latter:

...then use whatever virtualization program to present the USB drive to the guest operating system and, if your guest OS knows what to do with those file systems, they'll mount as though local. Making an ISO from the USB drive to then present to the guest OS is added work and will still get you the exact same result as presenting the USB drive to the guest.

Furthermore, I'm not sure what you mean by

Click to expand...

Why would you want to install macOS 13.4.1 on a pre-existing Windows VM? Even if you're trying to do nested virtualization (which I'm pretty sure isn't possible on a Mac), you're not going to have an easy time getting a Mac VM to run on a Windows hypervisor. If you're trying to create a Mac VM, then you should just create that VM from scratch on whatever hypervisor app you're using.

Also, worth pointing out that this is a night-and-day different process between Intel and Apple Silicon Macs.

Hello leoborges,

RE: gibMacOS

I opened the package,
I tried all the Terminal items,
But none would install it.

It contains these items:
Scripts
__init__.py
disk.py
diskwin.py
downloader.py
plist.py
run.py
utils.py
BOOTICEx64.exe
LICENSE
Readme.md
gibMacOS.bat
MakeInstall.bat
BuildmacOSInstallApp.py
gibMacOS.py
MakeInstall.py
BuildmacOSInstallApp.command
gibMacOS.command

Please also see the attached screenshot.

If you know how to install it, please advise.

Thanks,

Kind regards.

As Yebubbleman said above, you're really overcomplicating this. All you need to do is plug in your USB drive and then run:

sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/NameOfUSBDrive

That'll take care of everything else for you.
