If you have a developer account then you can easily get the macOS 12.0 Monterey installer file. You can update your Mac from macOS Big Sur to macOS Monterey. Besides that, you can download and check all the major updates. But, installing macOS Monterey on your Primary Mac is somehow risky because of its bugs and errors. Although, macOS Monterey is in developer Beta version and soon you will see the stable version at the end of this year.
If you have a developer account or no, that’s not a big issue. In this article, we are going to guide you on how you can create a macOS Monterey ISO image file. The main point to create a macOS Monterey ISO image is to install it on virtual machines. As you know, the macOS Monterey Beta version has bugs that can crash your primary Mac. Therefore, we are going to use the macOS Monterey ISO file to install it on Virtualbox and Vmware.
What I think, you don’t need to create macOS Monterey when you can download the macOS Monterey ISO image. The file is 16GB and it needs fast internet to download the file. Anyhow, creating an ISO file yourself is much better and you will learn the process.
macOS Monterey has amazing new features and lots of updates like Universal Control, FaceTime and SharePlay, Airplay to Mac, Shortcuts, Safari Tab Bar updates, and many more. Like macOS Big Sur, Apple included handy features in macOS Monterey. Therefore, you should try it and check all its updates.
How to Create macOS Monterey ISO Image?
We will create a macOS Monterey ISO Image file on our Mac computer using Terminal. Before going to start the steps, you need to download the below required files. However, to download macOS Monterey Assistant Package, I recommend you to download it directly from the Apple server. Because this link will be changed and not stable. Although there are more developers that can provide download links.
So, download macOS Monterey Assistant.pkg beta 1 and install it on your computer. Once you installed the Assistant package, the macOS Monterey installer will be added to the applications directly. After that, follow the below steps.
When the file successfully downloaded then make sure the file should be in the Applications folder. If the file was not there then you can’t create a macOS Monterey ISO File.
Step 1: Launch Terminal and follow the below codes one by one. Make sure, to not edit or change the command code. Copy and paste it as same.
Step 2: Create macOS Monterey Virtual Disk Image
hdiutil create -o /tmp/Monterey -size 13350m -volname Monterey -layout SPUD -fs HFS+J
Step 3: Mount Image to macOS
hdiutil attach /tmp/Monterey.dmg -noverify -mountpoint /Volumes/Monterey
Step 4: Use macOS 12 Createinstallmedia Tool to create an installer Image
sudo /Applications/Install\ macOS\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Monterey --nointeraction
Step 5: Unmount the Volume and install macOS Beta
hdiutil detach hdiutil /Volumes/Install\ macOS\ 12\ Beta
Step 6: Now, convert macOS Monterey.dmg to Monterey.iso for Virtual machines
hdiutil convert /tmp/Monterey.dmg -format UDTO -o ~/Desktop/Monterey.cdr
Step 7: Move and Rename macOS Monterey Image to Desktop
mv ~/Desktop/Monterey.cdr ~/Desktop/Monterey.iso
Once you applied all the above codes, then you should see a positive result. The macOS Monterey ISO file should be created and now you can use the ISO image in Virtual machines.
