Shiggitay Posted August 26, 2017 Share Posted August 26, 2017 I followed this guide and I ended up with a 9.4 GB ISO.... I know it's meant for VMWare etc installations, but how would I cut down on all the extras like printer drivers and languages? I'm trying to make a DVD burnable/bootable ISO. I'm currently trying to dd a USB stick I made as one of my attempts to ISO, but it's going to be too large for a standard single layer 4.7 GB DVD-R. Thanks in advance. 1 Link to comment Share on other sites More sharing options...
Deli Dumrul Posted October 6, 2017 Author Share Posted October 6, 2017 This method is simple and it is working.

AzJazz Posted October 8, 2017 Share Posted October 8, 2017 This method is simple and it is working. For new High Sierra Release; hdiutil create -o /tmp/HighSierra.cdr -size 5130m -layout SPUD -fs HFS+J hdiutil attach /tmp/HighSierra.cdr.dmg -noverify -mountpoint /Volumes/install_build sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build 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 mv ~/Desktop/HighSierra.iso.cdr ~/Desktop/HighSierra.iso Update: This worked for me, too (after modifying the last "mv" command). My previous installation issue was not relevant, as I was installing the High Sierra update while in a Mountan Lion VM. When I discovered a pre-packaged High Sierra VMWare VM on the web and did the recent High Sierra update with that, the InstallESD.dmg was created properly, and the createinstallmedia command worked fine. Thanks, Deli Dumrul and Guyver! 1 Link to comment Share on other sites More sharing options...
milligator Posted November 3, 2017 Share Posted November 3, 2017 I tried to create iso file from Mac OS 10.13.1 and ended up with the following error. Making disk bootable... Copying boot files... Failed to copy kernelcache, “prelinkedkernel” couldn’t be copied to “.IABootFiles”. Done. what can cause the problem? Size of the downloaded file:5,208,823,747 bytes (5.2 GB on disk) I am using 10.12 on VmWare. Can I update my running OS X 10.12 with just double clicking the downloaded file? 1 Link to comment Share on other sites More sharing options...

woggletog Posted November 27, 2017 Share Posted November 27, 2017 I have created ISO files using both scripts but neither ISO appears to be bootable. I get: PXE-E53: No boot filename received PXE-M0F: Exiting Intel PXE ROM Operating System not found The VM appears to be OK (the CD drive is first in the boot order) as it boots a Windows ISO without any problem. I am trying to create the ISO from a Sierra VM. This is using Workstation 14 Pro. Link to comment Share on other sites More sharing options...
woggletog Posted December 4, 2017 Share Posted December 4, 2017 Sorry - my mistake. By using the latest unlocker (211) and tweaking VMWare it boots OK. There is a good video on You-Tube. Link to comment Share on other sites More sharing options...
