MMEX Upate Problem

Hi, I'm probably missing something obvious but I can't get the update 1.1.5 to load on my Mac. What exactly am I supposed to drag where?  Alternatively, given that the updates don't appear critical (unless they include a minimise/maximise button) how can i switch the message off overtime I open MMEX?  Grateful for any advice,  thanks....

Well it took my tech-savvy son home for the holidays to explain that the drag and drop was the actual action required on the download, not a picture of what needed doing (does that make sense?) Now I get it :)
