Ive tried BelenaEtcher many times on a Mac. It can be a large or small file, but it always ends with a fail even when it hasnt failed and the file is there. Why is this?
Odd, I use it on a Mac nearly everyday @genesis1 … perhaps your OS is writing the .Spotlight folder to the SD Card nearly immediately after the flash finishes, thus altering the SD Card just slightly and causing the Etcher verification to fail when it goes to check what it wrote, versus what is actually on the card.
