What's the highest Mac OS capable of running Nexus Manager? May 19, 2015, 01:22:44 PM Currently we are running Nexus 10.1.3 with the latest version of Nexus Manager that came with that download. Using OS X 10.8.5 Mountain Lion I have no trouble connecting to Nexus Manager. However, when I try to use my laptop running OS X 10.10.2 Yosemite, I have no luck connecting to Nexus Manager. Is anyone out there running an OS higher than 10.8 successfully with Nexus/Nexus Manager v10.1.3? We are trying to decide which OS to upgrade to before subscribing to (ugh) Abode CC, but we have to keep in mind connectivity to our Nexus client software.
