Topic: Totalmix FX won't start with OSX 10.10.5
If TMFX does not start under OSX 10.10.5, please try the following steps:
Open the finder and navigate to Macintosh HD > Library > Audio > Plug-Ins > HAL
Copy "Avid CoreAudio.plugin" e.g. to the desktop (just to retain the file)
Delete "Avid CoreAudio.plugin" in the HAL Plugin folder
Reboot
