How to convert @Niresh High Sierra Zone DMG to a valid bootable ISO

Question

We are all at the mercy of @Niresh hard work here. While i am typing my hackintosh Yosemite zone is running on virtualbox roughly stable but it's way beyond my expections. After a little playing with hereYosemite i downloaded High Sierra DMG via torrent and and now i'm trying to do the same for High sierra zone. But as you now virtualbox can only boot from a bootable ISO. here is what i did to convert hackintosh high sierra to ISO. Unfortunately the result is not a valid ISO file. i guess many things should be added to the ISO file to make it a bootable valid ISO.Yosemite i downloaded High Sierra DMG via torrent and and now i'm trying to do the same for High sierra zone.

Code provided here is not commented so somethings to make it more readable.

The guide i used to convert the DMG is here

DMG reside in ~/Public

I used BaseSystem.dmg from @Niresh DMG file.

 

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

$ hdiutil attach /tmp/HighSierra.cdr.dmg noverify -nobrowse -mountpoint /Volumes/install_build

My BAD. The iso i made in post 1 is healthy and works

Ok i followed the how to geek's great post on installing High Sierra on my VirtualBox and right now it is installing High Sierra i created from @Niresh High Sierra zone image on my vm. But i think both official high sierra zone and Niresh high sierra zone uses the same BaseSystem.dmg file and there is no different between the two unless @Niresh is modified it's version. But to me it's not the same experience like the Yosemite zone and feels like an official install.

    • Hi! I'm new to the forum. I hope you can help me, that's what happens: I tried installing Hackintosh High Sierra Zone on my HP 15-r211nl laptop, followed the guide and all, but ended up always with the infamous allocation error. So I was struggling my mind to find a way though and finally found this osxaptiofix2drv-free2000.efi file, which replacing osxaptiofixdrv.efi file (after trying also osxaptiofix2drv.efi again without success),  removed the allocation error, but came up stuck with a line of plus signs and nothing else. After two days of going crazy, I decided to try Hackintosh Sierra Zone (instead of High Sierra), put it on the USB key, and again... allocation error. replaced again osxaptiofixdrv.efi with the beautiful osxaptiofix2drv-free2000.efi file, and...
      ...IT GOES! It started installation and rebooted. The problem is: After reboot, to complete the installation, plugged out my USB drive, and selecting boot MacOS, I get again the memory allocation error, like it is not using the osxaptiofix2drv-free2000 file i provided in the usb drive. WHY? So I decided to insert the USB back in and boot MacOS from there and.. it booted and completed the installation. But everytime I want to boot MacOS I need the USB plugged in and boot from there, otherwise memory allocation error. Now.. this is frustrating... I'm asking: Why (with the osxaptiofix2drv-free2000 file) i can install sierra but not High sierra? and... How can I manage to put the osxaptiofix2drv-free2000 efi file in my MacOS installation so I don't need the USB key plugged in everytime?     Please @Niresh help me... I am already gonna donate some money, but if you can help me i promise i will donate even some more. Thanks a lot. P.S. sorry for any grammar mistake...

    • Recently I tried to install Sierra Zone Hackintosh onto my Dell Inspiron N5567 Laptop. Installation was pretty fine. It booted up so well. The problems started during the post-installation process. Audio kext worked properly after some reinstalling. Wifi, Ethernet, and Bluetooth was unable to configure. When installing the graphics kext for Intel HD Graphics, it got installed properly and after restarting my laptop, there was a black screen after my Clover bootloader and it gets shut down.    My Laptop Specs: Dell Inspiron N5567 Intel Core i5 7200U 8GB DDR4 SODIMM RAM  AMD Radeon R7 M445 Graphics  2TB Hard Drive   The Drivers Include: Intel AC3265 Network/WiFi drivers Realtek ALC 3246 Audio Drivers Intel HD 620 Graphics Drivers AMD Radeon R7 M445 Graphics Drivers.   Please do consider this issue and come up with any solutions. I have checked youtube. No one has Hackintosh installed Hackintosh on the very same laptop series. Please help.
