Same image on and older mac works


Forwarding your question to the Etcher team.



MacOS Catalina is a beta version and we didn’t yet start porting Etcher for it.

Also it would be best to report Etcher issues in the github repo:

There we have an issue template that helps gather useful debugging information.


Argh. I attempted to get information from DevTools to add to git and flash was successful.

Tried another SD card today “something went wrong”
Where IS devtools?

Hi @dg12 I believe you can open the devTools with the key combination of cmd+alt+i . Let me know if that doesn’t work.

From devtools; console:

catalina IS preventing reading from Documents directory (see GitHub Issue)

Sorry about the confusion.

No worries. Thanks for the update. Cheers!

I had to run the app via terminal as root:
sudo /Applications/
in order to get it working. Not sure if that is advisable though.

That is not advisable indeed, please check this issue for an in depth explanation:

yes, “sudo” works!!
