Hi guys I just had the link updated to mac burner with firmware v1.0. The damaged error is actually an issue related to os high sierra and mojave new versions blocking apps from 3rd party developers, open a terminal and input this command to resolve it: sudo spctl --master-disable.
A mac burner which will auto-update to the latest firmware and is compatible with all current OS without needing to change anything is being worked on but progress is slow, sorry about this guys hopefully it will be ready before the end of the month.
I don't have High sierra or mojave!
I havent updated in ages and still on Old Sierra
