Hi there, Running OS X 10.10 Public Beta 4 (clean install) and iOS 8.0 o my iPhone. I know my Mac is unsupported for Handoff, but I have a single question regarding Notification Center: All my iMessages go in synch between the devices, but NOT A SINGLE FINDER NOTIFICATON shows up, although I have set up in the System Preferences > Notification as to allow displaying of badges, alerts and sounds on the Mac. Do you happen to have any idea why this behaviour? I even hear a new iMessage sound when somebody writes to me, but I have to open the Messages app on my Mac to see what has been written. Annoying. Is there any way to make Notification Center work properly? Thank you! Mark.
