Didn’t it show up under “Finder” section? Think that it’s under the Network. My MacMini sees MBL & I can play music from it using VOX running OSX 10.7, 10.8, 10.9.
Don’t recall how it got done; but the MacMini was connected to the router via wifi when the MBL showed up but have now changed it to wired & the MBL is still there.
