安装python2.7最新版，自带pip，通过pip安装six和pyinstaller扩展，打包unlocker为exe程序：

pip install six pyinstaller

将pyinstaller所在目录加入到path，使用win-build.cmd打包exe程序，关闭vmware和开启的虚拟机，管理员运行win-install.cmd即可。
新建mac osx虚拟机配置文件新增：

smc.version = 0
#禁用HiDPI，不然分辨率自动调整为低分辨率
gui.applyHostDisplayScalingToGuest = "FALSE"

通过app store下载最新High Sierra系统，然后执行：

hdiutil create -o /tmp/macOSHighSierra -size 5200m -layout SPUD -fs HFS+J
hdiutil attach /tmp/macOSHighSierra.dmg -noverify -mountpoint /Volumes/install_build
sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build
mv /tmp/macOSHighSierra.dmg ./
hdiutil detach /Volumes/Install\ macOS\ High\ Sierra
hdiutil convert macOSHighSierra.dmg -format UDTO -o macOSHighSierra.iso
mv macOSHighSierra.iso.cdr macOSHighSierra.iso

10.14

hdiutil create -o /tmp/macOSMojave -size 7000m -layout SPUD -fs HFS+J
hdiutil attach /tmp/macOSMojave.dmg -noverify -mountpoint /Volumes/install_build
sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build
mv /tmp/macOSMojave.dmg ./
hdiutil detach /Volumes/Install\ macOS\ Mojave
hdiutil convert macOSMojave.dmg -format UDTO -o macOSMojave.iso
mv macOSMojave.iso.cdr macOSMojave.iso

更新：
10.15

hdiutil create -o /tmp/macOSCatalina -size 8100m -layout SPUD -fs HFS+J
hdiutil attach /tmp/macOSCatalina.dmg -noverify -mountpoint /Volumes/install_build
sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build
hdiutil detach /Volumes/Install\ macOS\ Catalina
mv /tmp/macOSCatalina.dmg ./
hdiutil convert macOSCatalina.dmg -format UDTO -o macOSCatalina.iso
mv macOSCatalina.iso.cdr macOSCatalina.iso

12.3:

hdiutil create -o /tmp/macOSMonterey -size 13000m -layout SPUD -fs HFS+J
hdiutil attach /tmp/macOSMonterey.dmg -noverify -mountpoint /Volumes/install_build
sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build
hdiutil detach /Volumes/Install\ macOS\ Monterey
mv /tmp/macOSMonterey.dmg ./
hdiutil convert macOSMonterey.dmg -format UDTO -o macOSMonterey.iso
mv macOSMonterey.iso.cdr macOSMonterey.iso

10.15后系统自带softwareupdate可选择相应版本系统下载：

softwareupdate --fetch-full-installer --full-installer-version 10.15.7 

也可使用gibMacOS下载。

新建分区：

gdisk /dev/sdc
Command (? for help): n
Partition number (1-128, default 1): 
First sector (34-60555230, default = 2048) or {+-}size{KMGTP}: 
Last sector (2048-60555230, default = 60555230) or {+-}size{KMGTP}: +200M
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): ef00
Changed type of partition to 'EFI System'

Command (? for help): n
Partition number (2-128, default 2): 
First sector (34-60555230, default = 411648) or {+-}size{KMGTP}: 
Last sector (411648-60555230, default = 60555230) or {+-}size{KMGTP}: 
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300): af00
Changed type of partition to 'Apple HFS/HFS+'

Command (? for help): w

格式化分区：

apt-get install hfsprogs
apt-get install dosfstools
mkfs.vfat -n EFI /dev/sdc1 
mkfs.hfsplus -v 'Install macOS Sierra 16A323' /dev/sdc2 

dmg转img：

#yum -y install zlib-devel bzip2-devel openssl-devel
#git clone https://github.com/Lekensteyn/dmg2img.git
#cd dmg2img && make
apt-get install dmg2img
dmg2img -v -i macOS\ Sierra\ 10.12\ \(16A323\).dmg -o mac.img

复制镜像到分区：

mount /dev/sdc1 efi/
mount /dev/sdc2 osx/
mount  -o loop Clover-v2.4k-4200-X64.iso /mnt/efi/
cp -rf /mnt/efi/* efi/
mount -t hfsplus -o loop mac.img /mnt/osx/
cp -rf /mnt/osx/* osx/

不能正常引导，后续再研究。
