When I first bought my DYMO 330 Turbo two years ago, it worked fine with OSX. After several updates to the OS my label writer quit working and now with OS 10.4.7 I now have a dead label writer. OSX does not recognize the print driver. Even when attempting to install the printer through the "Printer Setup Utility". None of the installed drivers are recognized. Old 6.1 nor the New 7.6 Dymo application installers work. DO NOT BUY any of their products when using MAC OS X until the manufacturer of this fine label writer gets it to function with Mac OS 10.4.7. The writer is junk without a working print driver. Makes a great paper wieght though. How this printer works with Windows is beyond me.
