DS4 may not work correctly on some older machines. We are currently trying to understand why we see some specific problems and fix them. Until then we have an alternative build that should fix most of these issues. Specifically, if you see any off the following, please install this alternative build and then try using DS4 again:
Before you install this Alt Build, go to your system tray on the Mac which is in the top
right hand corner of your screen. There you will see a small green DS4 try icon. Click on this icon and
then select close. After you have close the DS4 tray icon, you can install the alt build OVER TOP the existing build. There
is no need to uninstall first.
