The J addon JOD now runs on Macs. You can update JOD, or install it for the first time, with JAL. JOD now runs on all the major J hosts: Windows, Linux and the Mac.
To keep track of host specific features I have started a series of version documents. The Mac document is here.
At the upcoming J conference, (July 23-24, 2012), in Toronto I will show an iPhone version of JOD. And, as a reward for attending the conference and my little presentation, Writing Portable J addons, I will be raffling off hardcopy printed versions of the JOD manual.
An updated PDF version of the JOD manual is available here. For more see The JOD Page.
