make bootable golden gate usb installer (2 Viewers)

This morning apple announced MacOS Golden Gate but did not explain how to make bootable golden gate usb installer

You can make a Golden Gate bootable USB installer by first formatting a 32GB or 64GB usb as Mac OS Extended (Journaled) and naming it Untitled.

After downloading the Golden Gate Beta 1 installer (which so far is nameless, even though we now know it has the name Golden Gate) you can run this in Terminal to make the bootable USB:

sudo /Applications/Install\ macOS\ 27\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

The command for future betas will probably change to

sudo /Applications/Install\ macOS\ Golden\ Gate\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

and then with public release (or even release candidates) to

sudo /Applications/Install\ macOS\ Golden\ Gate.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

To find beta full installer you may run code in terminal

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-27seed-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
curl -s $file | egrep -A 1 -m 2 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done

much later when public release happens to get public release full installer change this to

for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-27-1.sucatalog | grep com_apple_MobileAsset_MacSoftwareUpdate.plist | grep -Evw '(com_apple_MobileAsset_MacSoftwareUpdate.plist.integrityDataV1)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
curl -s $file | egrep -A 1 -m 2 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
echo $file | sed -e "s/com_apple_MobileAsset_MacSoftwareUpdate.plist/InstallAssistant.pkg/g"
done
