Did you forget?
Still waiting on the revised Guide & hopefully with English language screen shots. Note: another site usually has somewhat newer Clover versions that the one linked in the Guide: https://gitlab.com/Syncanvas/build_clover/tree/master/build
The Guide step 7: "Install Clover Bootloader in SSD" shows major different Clover options compared with the Clover version 4903 included with Mojave 10.14.4. And the language used in the screen shots is Brazilian, while the text is in English. So: a little too confusing. Note: the balenaEtcher program is also available in a Windows version, which works fine for "burning" the .RAW file to the 16 Gb USB thumb drive while using Windows.
