if this isn't already resolved I had the same issue today but when comparing it to the SHA256 checksum found it was corrupt. I just redownloaded the ISO and all was good

Hello, actually I tried it a week later on another pc, redownloading the .iso on another OS (windows Instead of Mac), and the same, balena crashes

I am also having the same issue, but with an Ubuntu 20.10 ISO. I was having the same issue on both macOS Catalina 10.5.7, as well as macOS Big Sur 11.0.1 (Intel).

is it 64bit?

if so follow this

Run this command in your terminal in the directory the iso was downloaded to verify the SHA256 checksum:
echo "3ef833828009fb69d5c584f3701d6946f89fa304757b7947e792f9491caa270e *ubuntu-20.10-desktop-amd64.iso" | shasum -a 256 --check

Thanks.. in the end I solved by using a previous version of balena

take a look at #3358 and try this version - EDIT: just realised this link is balena team only will update when v1.5.112 is released
