I wanted to open an existing media, but i click on new media (mistake!!!)
as it is a blank media it did not appears in the finder, and clicking on reveal in Finder did nothing. and I didn’t find the way to get out of that but rebooting…
Could you tell me what to do in such case?
You need to make sure that the System Preference item CDs & DVDs is set up to open blank media in the Finder. Then you can just eject blank media that you accidentally insert. I created a video that shows how to do it which you can find here:
