At present, EndNote X8.x is a 32-bit application. Thank you for your product suggestion in regards to future compatibility for macOS 10.13. I have added this to our Product Suggestions area of the Forum so this can be viewed by the parties who make decisions about the future development of EndNote.

indeed my EndNote stopped working correctly once I upgraded to macOS High Sierra 10.13.4
Endnote slow reactivity to comply with changes announced years in advance is endemic
bye bye endnote I am switching after years of use and I won't come back
