VirtualBox
6.1 (or later) should be used as it has built-in APFS boot support.
Making ISO
Sierra
- https://qiita.com/sho7650/items/c24aa487938ac177de01
- This method actually works for Sierra/ElCapitan/Yosemite/Mavericks.
- (MountainLion/Lion just require to convert InstallESD.dmg.)
- https://support.apple.com/en-us/HT201372 's Sierra InstallOS.dmg has issues around createmedia, but this script is not affected.
- It is possible to extract InstallESD.dmg from InstallOS.dmg or InstallMacOSX.dmg using xar command.
sierra.bash
hdiutil attach ./InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/esd
hdiutil create -o Sierra.cdr -size 7316m -layout SPUD -fs HFS+J
hdiutil attach Sierra.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/iso
asr restore -source /Volumes/esd/BaseSystem.dmg -target /Volumes/iso -noprompt -noverify -erase
rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages
cp -rp /Volumes/esd/Packages /Volumes/OS\ X\ Base\ System/System/Installation
cp -rp /Volumes/esd/BaseSystem.chunklist /Volumes/OS\ X\ Base\ System/
cp -rp /Volumes/esd/BaseSystem.dmg /Volumes/OS\ X\ Base\ System/
hdiutil detach /Volumes/esd
hdiutil detach /Volumes/OS\ X\ Base\ System
hdiutil convert Sierra.cdr.dmg -format UDTO -o Sierra.iso
mv Sierra.iso.cdr Sierra.iso
rm Sierra.cdr.dmg
HighSierra/Mojave/Catalina
- I recommend cloning https://github.com/kholia/OSX-KVM/ and use
create_iso_*.sh. Note that git is preinstalled on macOS. - By the way, note that 10.15.2+ are not supported yet.

Sierra hack
-
If the Sierra is 10.12.4 (or 5/6), virtualbox cannot startup the ISO.
- https://www.virtualbox.org/ticket/16644
- Thanks to widhaya3 (https://www.virtualbox.org/ticket/16644#comment:33), we could implement hackintosh approach.
Maybe nvram cannot be shared with/without this hack. Be careful.
