Install macOS Big Sur.app Can't find .dmg

[camelia]

I can't find the following .dmg into Install macOS Big Sur.app

InstallESD.dmg

BaseSystem.dmg

Are they hidden or they don't exits in the installer?

Thanks

Those are no longer in the installer.

If wanting to create a bootable installer/thumbdrive, just need to run the command for Big Sur:

Create a bootable installer for macOS - Apple Support

Use an external drive or secondary volume as a startup disk from which to install macOS.

support.apple.com

sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

Any instructions that need BaseSystem, InstallESD are out-dated.

Thank you

I know how to create a bootable installer for macOS 😎

A friend of mine downloaded the installer a few monts ago, And I downloaded recently
The problem started when I did not mark which USB stick has the new version and which one has the old version

I was looking for

InstallESD.dmg

BaseSystem.dmg

To hash them (Checksum) and find out the difference between both version

Is possible to know which version of the macOS installer contains each USB stick?

Thanks

Open installer.app/Contents/Info.plist in TextEdit.

Scroll to "DTPlatformVersion".

Does this terminal commands still works in macOS Big Sur?

hdiutil attach /Applications/Install\ macOS\ Mojave.app/Contents/SharedSupport/BaseSystem.dmg -noverify
defaults read "/Volumes/macOS Base System/System/Library/CoreServices/SystemVersion.plist" ProductVersion
defaults read "/Volumes/macOS Base System/System/Library/CoreServices/SystemVersion.plist" ProductBuildVersion
hdiutil detach /Volumes/macOS\ Base\ System

Thanks

Big Sur does not use the same macOS installer file setup as on previous macOS versions.
Those files do not exist in those locations in Big Sur.

NoBoMac's post will show you the version the installer app will install.

Even simpler: Get Info on your USB stick, that bootable volume where you have your Big Sur installer.
You will see the software version in that info window.

Ok now I know how to know the version in macOS Big Sur
But this terminals commands are not working in macOS Catalina only in macOS Mojave why?

Thanks
Camelia

hdiutil attach /Applications/Install\ macOS\ Mojave.app/Contents/SharedSupport/BaseSystem.dmg -noverify
defaults read "/Volumes/macOS Base System/System/Library/CoreServices/SystemVersion.plist" ProductVersion
defaults read "/Volumes/macOS Base System/System/Library/CoreServices/SystemVersion.plist" ProductBuildVersion
hdiutil detach /Volumes/macOS\ Base\ System

I tried both the Mojave and Catalina installer apps.
Both work the same, showing the files that are included with those commands that you posted.
Both Mojave and Catalina show the correct results.
I can't explain why your examples don't work for you, but both Mojave and Catalina installers work for me

The change comes with Big Sur. No such file paths exist in the Big Sur installer app.
