Apple - No hover feedback in OS X Yosemite
I had the same issue with my Mad Catz MMO 7 and I fixed the problem! If you download the latest driver software from http://madcatz.com/downloads/ for Mavericks (OS X 10.9) it fixes the problem. You will have to restart your computer in the process.
I reached out to MadCatz support and they have a workaround to get the Mavericks drivers working in Yosemite:
Go to System Preferences -> Security & Privacy -> Privacy -> Unlock to make changes
In the list "Allow the apps below to control your computer" ticked the following:
- MadCatzSmartTechnology
- Mad Catz Editor”
For me the same with a Logitech MX connected to a unifying receiver. I did repair the mouse with the Unifying software provided by Logitech and then it worked again.
