Hello afonsopatrao,
We are actively testing EndNote X7.2 against the Golden Master version of Yosemite. However, we cannot claim official compatibility until the release of the final version. See Gillian’s response about this EndNote practice from last year’s Maverick’s release:

Seeing that the Yosemite release is to happen shortly, I will keep everyone updated here, as well as on https://www.facebook.com/EndNote
https://twitter.com/EndNoteNews
and of course, in our new community in EndNote online.
Thanks for writing,
Meredith M.
EndNote Team
