I was using another script that worked fine with 10.9/10.10/10.11 but somehow not for Sierra, even though I edited the pathnames properly. This worked perfectly and I can install the Sierra iso in VMWare.

Thank you! Worked like a charm. If you run into the issue where the first line ends with Resource busy you just need to unmount the Sierra install image in diskutil.

I used this to create a bootable USB. Just dd the result Sierra.iso as usual, works like a charm. I previously tried two GUI apps "Install Disk Creator" and "DiskMaker X 6" but both had issues.

I tried running the above commands, but this line:

hdiutil create -o /tmp/Sierra.cdr -size 7316m -layout SPUD -fs HFS+J

failed for me with the error message:

hdiutil: create failed - No space left on device

Any suggestions?

Note, I'm trying to run this code on OS X Lion.

Unfortunately I still get the VirtualBox message that originally brought me here: "FATAL: No bootable medium found! System halted!"

PS: I'm trying to create a bootable Yosemite.iso from Yosemite.app for VirtualBox on a Mac host.

Howdy all, I am attempting to install a guest operating system in VMware Workstation from Sierra.iso. However, it spits back the following error:

This file is not a valid disc image. Please make sure you have selected the correct file.

Does anyone know why VMware is rejecting the ISO file? @budwig?

@seanthewebber Have you ran the unlocker for unlocking macOS on VMWare?

Btw, everyone, you can run bash <(curl -s https://gist.githubusercontent.com/julianxhokaxhiu/6ed6853f3223d0dd5fdffc4799b3a877/raw/b56a93d8523b132c0a156b968263a5814b2dab90/create-iso.sh) to install this script without downloading ;-)

Any idea how to create macOS 10.13 beta iso from the installation app?

BaseSystem.dmg/.chunklist are outside the InstallESD.dmg. But even if I use them, an error that OSInstall.mpkg is damaged, appears at High Sierra installation.

watching for correct commands for the latest high sierra beta too :)

For High Sierra iso, I tried to put BaseSystem.dmg at "/System/Installation/Packages/" or at "/" as shown above, but the same error appears: OSInstall.mpkg is damaged (since it can't find BaseSystem.dmg).

Pacifist gives the following error when opening InstallESD.dmg.

Update: I managed to install High Sierra as an update to Sierra in VirtualBox. This blog helped me a lot.

I'm still curious how to create iso for High Sierra, though.

It hangs at IOConsoleUsers: getIOScreenLockState

Thank you.

What's the difference between this process and running /Applications/Install macOS <Version>.app/Contents/Resources/createinstallmedia tool on an image file, then converting it to an ISO?

@HoudayerPierre

Stop on "IOConsoleUsers: getIOScreenLockState" too.
