Combination of some codes and applications to create macOS installation media outside Mac app store.
Thanks me later :3

Honestly, the main reason is I've limited Internet. I can't download the whole 8GB, 12GB at one stroke. So, I've to download multiple times and MAS doesn't support it. Moreover, I want to save downloaded installer so that I can use them next time. That's why I made this script.

git clone https://github.com/htmm/macos-bootable-usb.git
cd $HOME/macos-bootable-usb
chmod +x ./creator.command
chmod +x ./Create_Install_Media.command

cd $HOME/macos-bootable-usb
./creator.command

cd $HOME/macos-bootable-usb
./Create_Install_Media.command

it's still in beta. Simply just run the script, answer the question and go!

DISK SELECTION information can be found in diskutil > table > Device. In this example disk3. So, TARGET_DISK become /dev/disk3.
