So far the 2300 series is not supported by OS X, the 2200 series is. I tried downloading the 2200 series software attempting to use as a "maybe this will work" mode, however during the final step of the setup the newer 2300 series is not recognised by the 2200 software and setup can not be continued. Also tried the installation disk that came with the 2300 series in case Lexmark made a mistake and included the OS X drivers, not such luck. The hit and miss with OS X drivers is perplexing, why would Lexmark produce drivers for a previous series and not carry over the drivers for the next? From a marketing viewpoint this does not make any sense.
