Semi success! mac working with the Megado - this is a mac OS issue not Megado. Took several steps but fcan maintain connection for a good amount of time. Contact me if you also have an issue.
(I cannot get my mac with mac PCW to communicate with my Megado loom, I just got the mac drivers and the program is sluggish and says it can find the port but cannot open it. Any Megado users - what do you use?)
