Hdiutil convert ~/Desktop/InstallSystem.dmg -format UDTO -o ~/Desktop/HighSierra.iso THANK YOU, finally a working solution, tested myself a short time ago without any issues whatsoever, but I added: Sure would be nice to figure this crap out.ĭammit Apple, why are you making things so difficult.

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.

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.Īgain it just seems stupid how this is working out but that's what happens I suppose. 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 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. 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.
