I downloaded Etcher again this morning. Clicked the same download button and off we went. This time it was a .dmg file! Excellent! And it opened! And it had a simple installer…which simply told me the current version of Etcher is incompatible with Mac OSX Lion. Why don’t you put system requirements anywhere on your website? Perhaps I could use Etcher CLI but there are no adequate instructions - what instructions there are, seem to presuppose a lot of CLI knowledge.
