Something Went Wrong | MAC OS X 10.14.6 | Etcher 1.5.111

Yes of course so when I said works perfectly it burned the file I needed onto the SSD card on a windows computer. Yes disk repair to see if the issue was my Mac that needed the repair. After doing the utility disk repair still had the same issues. The error was “ File closed”.

I also use Etcher on an Intel-based Mac, and it works for me. I just used it today to flash an SD Card, and it worked fine. I am on Mac OS 11.2.3, and Etcher 1.5.120. You might want to try opening up the Developer Tools Console while you are attempting to flash on the Mac, and see what you can capture in the logs to share here with us. Command+Shift+I will open them up. Thanks!
