Mac OS High Sierra

Hello, I have Endnote X7.7.1 and I’m thinking about updating my Mac OS (currently El Capitan 10.11.5) to High Sierra. Is my version of Endnote still going to work? I already made the mistake of buying Endnote a few years ago, then updating my OS, and then finding that Endnote didn’t work, and then I had to buy X7.7.1.  I have been googling this compatibility question and searching on this forum, but didn’t find a clear answer – except that X7.7.1 works with the first version of Sierra but the PDF view function doesn’t work…   Thanks in advance.

EndNote X7 will work on High Sierra but you will have issues with the pdf functions on High Sierra.

So if you use the PDF functions with EndNote I would suggest staying with El Capitan 10.11.5.
