#Mac os sierra iso bootable cd iso
Nocturnius posted instructions in the other thread and this will make a bootable dvd: īut the iso still can't be used for vmware fusion.
Sooner or later a working method will make itself known someplace so again, I'm not in a major hurry to get this ISO created, I can and will wait till someone with a lot more talent for this makes it a reality.īut it's not about making a bootable USB stick, that's easy. I don't comprehend why Apple does this but it's not relevant I suppose. None of the currently available instructions or methods are working to create the ISO at this point - the methods that worked for previous versions of OS X (even the GM candidate build of El Capitan itself from just a few weeks ago) DID actually work with the well known and published methods of creating an ISO from the installer app, but the final release of El Capitan has some changes in it and those methods don't work anymore, none of them.įor me personally I want to be able to create a working functional-without-issues bootable ISO which is the most efficient tool to use for virtualization purposes when it comes to installing the OS above and beyond all other means of doing such a thing, better than physical media of any kind whether it's a bootable hard drive, bootable SSD, bootable optical disc aka DVD, or even the popular bootable USB stick nowadays. As of only a few hours ago I can confirm that this bootable dvd not only boots but also successfully installs High Sierra.As has been stated a few times in this thread specifically - reading is fundamental, folks, but reading with comprehension is a must - the topic at hand is about creating a bootable DVD (since El Capitan is so large it requires a DVD9 single sided dual layer media) - it is not about making a bootable USB stick which is easy and El Capitan's installer even has that capability from the command line (the createinstallmedia command).Īpple has modified things yet once more and now it's either completely impossible (unlikely) or just very damned difficult (the most likely case) to create a bootable DVD from the El Capitan installer app. It won't boot computers already formatted as apfs.Īttempts are still underway to make an apfs version of the bootable iso which may lead to a dual bootable bluray capable of booting up computers in both formats.
#Mac os sierra iso bootable cd install
Where you replace "YOURNAME" with the username for the account you are logged into at the time.Īnd then boot to startup manager with option key to select the dvd and install High Sierra from it.īUT - as it is formatted as hfs+ it will only boot up computers in hfs+. Sudo hdiutil burn /Users/YOURNAME/Desktop/HighSierra.iso You can then use this to burn it to a dual layer dvd:
Hdiutil convert ~/Desktop/InstallSystem.dmg -format UDTO -o ~/Desktop/HighSierra.isoĪnd then you can rename to HighSierra.iso. Hdiutil detach /Volumes/Install\ macOS\ High\ Sierra
Sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia -volume /Volumes/install_build Hdiutil attach /tmp/ -noverify -mountpoint /Volumes/install_build Hdiutil create -o /tmp/HighSierra.cdr -size 5130m -layout SPUD -fs HFS+J
We can now make to bootable iso with the following commands: And the situation is now somewhat improved.
