EndNote 7 is not able to open any .nbib files that I download from pubmed. I have tried in Firefox, Chrome, and Safari on my Mac (through research after I found safari is not compatible, and chrome is not reliable, but nonetheless my DL from FireFox had the same issue). All attempts result in the file being grayed out, so I am unable to select it. Any suggestions? I am new to EndNote, so my apologies if there is a simple solution I have missed. I did download the EndNote “How-To” guidebook but did not find a solution. Thanks in advance!
