problems installing echer on 2012 Mac mini

I’m running Mojave after Catalina crashes
I can’t get ecther dmg for 10.10.5 Mojave and I can’t upgrade to 10.10.11 el capitan and video instructions talking about 10.10.12 Sierra.
Is there an easy way to get around this problem?
thank you for your answers.

Hi Gyorgy, the only thing I can think of would be to try downloading and installing an older version of Etcher, but this of course means you don’t have the latest security, features, and improvements. But, for example, if you look at version 1.2, which was released in 2017, perhaps that would work for you? Release v1.2.0 · balena-io/etcher · GitHub

You can click on Downloads to get the installer. Hope that helps!
