Not until after I opened the packaging and attempt to install the software did I discover that this drive is incompatible with Mac OS X. I e-mailed tech support and received a single line response: "We don't support Mac OS X". And then I installed it in OS 9 and found that it *still* didn't work properly with both Disc Burner and Toast. I stuck to just using Toast, and then a week later the drive stopped ejecting CDs. I gave up and returned the unit.
