I’m trying to restore MacOS ‘High Sieera’ to usb using transmac on windows 7 now.
However, the following alerts are displayed and can not be executed.
The dmg file uses the file downloaded from here.→
It’s actually moot that you can’t use Transmac on that image, as the image itself is a delta updater & not a full installer.
You can only get a full installer from the Apple App Store, for which you will need a Mac.
