Hi I need to convert a Windows 7 from virtualbox to a file.iso I want to transfer this.iso file to an usb stick and install Windows 7 to another machine (without.
First, thanks for the High Sierra iso script. You may add 'rm /tmp/BaseSystem.dmg' at the end. Using the iso in VirtualBox, I selected the 'Reinstall macOS' option: Then installer requires Internet connection (may be to download the restore image) and the Continue button does nothing. It silently fails (no errors appear). I don't see any option how to configure the Internet connection, neither I want to download anything from Apple. So, I just can't use this iso in VirtualBox. However, I was able to install High Sierra as an update to Sierra.
Add Iso To Virtualbox
This helped me a lot. Edit: Updated for final release. Another way is to use the built-in createinstallmedia tool to install to that blank image, and then convert the image to iso. Well, I've been trying to create a functional bootable installation ISO for High Sierra for like 2 weeks now and I have to say I'm getting sick of doing it over and over again and never getting it to work. I used the original script above and had no success - what I end up with is a 9GB+ ISO file that will boot, yes, but it only boots to the remote disk install method where it has to contact Apple to pull down the installation files every single time and that seems a bit stupid considering they're all right there on the ISO I just created. So, when I saw that newly updated one for the final release posted earlier I fired everything up yet again and gave it another shot and, well, the same results again.

I don't particularly know why this is happening, perhaps Apple added some check code in High Sierra so it can detect when it's being used in a virtual machine (I'm using VMware Workstation Pro 12.5, I know that version 14 was just released but I'm not going to touch that right now) and then it just craps out with the remote disk installer instead of accessing the actual files on the ISO. Again it just seems stupid how this is working out but that's what happens I suppose. I still have hope a solution will present itself but, even that updated script that should work for the final release seems like it would but, at least in my usage of it, still just gives me a 9GB+ ISO that can only do the most basic thing which is the remote disk installation method. Sure would be nice to figure this crap out. Dammit Apple, why are you making things so difficult.:). Halabibk: THANK YOU, finally a working solution, tested myself a short time ago without any issues whatsoever, but I added: hdiutil convert /Desktop/InstallSystem.dmg -format UDTO -o /Desktop/HighSierra.iso to the end to get the final ISO conversion done which is followed by just renaming the HighSierra.iso.cdr to HighSierra.iso manually and then deleted the InstallSystem.dmg of course to get that space back. Again, thanks for sharing that solution.
The DMG file can be burned to a CD or mount as a normal volume on Macintosh computers. Usually, the data in DMG file is stored in compressed format.

Virtualbox Dmg File
Now we convert the DMG disk image file to an ISO disk image file (technically a CDR file but it’s the same as an iso) hdiutil convert /tmp/Mojave.dmg -format UDTO -o /Desktop/Mojave.cdr. Finally, we rename the CDR file extension to ISO to convert the CDR to ISO: mv /Desktop/Mojave.cdr /Desktop/Mojave.iso. That’s it, now you should have. Convert DMG to ISO options. When trying to convert a DMG to a ISO or CDR file for MacOS X, we have two options available. The first one is by using just Disk Utility, a preferred method if you don’t like working with Terminal. The second method is by using the command line by using Terminal.
EDIT: Ok, I used those instructions in the post above (halabibk's post) and the first time I did it I got it to work, it installed just fine without a single issue. But then I got stupid and decided to do it again on another drive and the second time it didn't work: the ISO remained bootable, and it did the installation, but the resulting VM wasn't bootable at all. World market employee handbook. I did some checking and of course even though I had manually chosen to format the virtual hard drive as HFS+ the installer created the APFS container and that borked everything so now I'm attempting to do this in another manner (because that was done using an SSD where the virtual hard drive vmdk file resided). Issuing your command before unmounting the install disk image produced a 'resource not available' message for me. I guess it can't convert the disk image while the image is mounted. I can confirm the following commands gave me an ISO image that successfully installed High Sierra 10.13 final downloaded from the app store to an Actual, Real Airbook via USB DVD drive, using the APFS container with zero issues. Wifi was disabled before beginning the install.

Took a looooooong time to transfer files from the DVD, but it worked 100%. Looks like the APFS issue you mentioned is something in VirtualBox, not something wrong with the image itself. Hdiutil create -o /tmp/HighSierra.cdr -size 5130m -layout SPUD -fs HFS+J hdiutil attach /tmp/HighSierra.cdr.dmg -noverify -mountpoint /Volumes/installbuild sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/installbuild mv /tmp/HighSierra.cdr.dmg /Desktop/InstallSystem.dmg hdiutil convert /Desktop/InstallSystem.dmg -format UDTO -o /Desktop/HighSierra.iso PS - PowerISO said no conversion was necessary when I attempted to use it to convert the DMG to ISO, and the file sizes were identical. When I run the script (edited for the final release) it fails on line 6. I ran each line separately in Terminal. I even re-downloaded the installation file just in case. This worked for me using an increased size for the base image.
Project management certification. Thanks to all contributers! Hdiutil create -o /tmp/HighSierra.cdr -size 5500m -layout SPUD -fs HFS+J hdiutil attach /tmp/HighSierra.cdr.dmg -noverify -mountpoint /Volumes/installbuild sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/installbuild mv /tmp/HighSierra.cdr.dmg /Desktop/InstallSystem.dmg hdiutil detach /Volumes/Install macOS High Sierra hdiutil convert /Desktop/InstallSystem.dmg -format UDTO -o /Desktop/HighSierra.iso. On MacOS 10.13.2: If you get a Failed to copy kernelcache, “prelinkedkernel” couldn’t be copied to “.IABootFiles”. Error during the createinstallmedia step, increasing the size of the image to 5530m worked for me.
When I try to follow steps from the Dec 26, 2017 comment, I hit the problem where creatinstallmedia fails trying to erase /Volumes/installbuild. I get the same error as: $ sudo /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/installbuild Password: Ready to start. To continue we need to erase the volume at /Volumes/installbuild. If you wish to continue type (Y) then press return: y Erasing Disk: 0%. Error erasing disk error number (22, 0) A error occurred erasing the disk.

I'm trying to run this on 10.12.6 (Sierra). I haven't run the upgrade yet. The download in /Applications/Install macOS High Sierra.app looks ok, it is 4.9 GB, (4,968 MB). If I run createinstallmedia using a physical 8 GB USB thumb drive it succeeds. were you able to figure it out? Any ideas from anyone welcome.
