share from photos not working on 1 mac, works on other

[jimNH 1]

I have two macs, both running 10.11.5 beta, and evernote 6.6. 453323 app store; photos v1.5;

They share the same photo stream, and evernote is logged into the same acct.

When I share a photo on my 13" mac it immediately goes into evernote and then evernote bounces in the dock to tell me its a got a new note...

When I share the same photo (or any other) on my other mac I get the dialog to enter the name, then nothing seems to happen...

Where should I look to figure out whats amiss? I started to read the extension docs since I do sw dev, just havent dont any xcode stuff.

thanks
