There were rumours of such a release earlier, but now it's official. You can actually drive your Up! printer directly from your Mac.
The version 1.0 software they've provided for Mac is not quite the same as their Windows version 1.12, as some features are not present. On the other hand, it appears that they've done a rather good job on the user interface. And if you read Fabbaloo, you'll know we appreciate simplicity.
