I downloaded latest ver of Etcher on MacBook Pro after selecting Linux Mint ISO I get the following error msg : Error: (0 , h.requestMetadata) is not a function. what is. the problem and how to fix?
I can’t tell the exact cause from that message alone, but a broken ISO is cheap to rule out first. The same error also showed up in another thread here last December with a completely different image, so it may not be your download at all. Still, the first thing I would do is verify the ISO: Linux Mint publishes a sha256sum.txt for every edition, and their official verify instructions show the check for macOS too - in Terminal run shasum -a 256 on your downloaded file and compare it with the sum for your edition. If it does not match, download the ISO again. If it matches, grab the current Etcher from the balena Etcher site and try once more, and if it still fails I would open an issue in the Etcher GitHub project with your macOS and Etcher versions so the developers can look at it.
