With the advent of Mac Mavericks, function of some open source design software linked to XQuartz was lost. Macosforge now provides an updated X11 for OS X 10.6 or later (including Mavericks). X11 is required to run Inkscape, a vector program, and ArahPaint5, a paint and drawing one that can be viewed being used in this video. Version4 is also included in a package with a free demo for ArahWeave. All have potential for creating and working with images, particularly useful in development of large format motifs for download to knitting machines.
