As the German forum is no help, hopefully I will find some help here:
I have moved from a Mac Pro 2012 to a new version 2013, so I had to install my Plextor BX950SA BluRay burner in an external USB 3.0 exclosure.
Toast Titanium is working fine with this drive, but Wavelab is not burning any more. It used to work fine before, when the burner was installed inside the Mac Pro 2012. I assume this has something to do with USB 3.0
I upgraded the drive firmware to the latest version, but Wavelab is still not burning.
When I start to burn the CD the dialog comes up, but the drive never starts burning. It will spin, but not burn.
Anybody has an idea?
