Let me see if I follow what your train of thought here. You have created content in Penultimate.You want to "edit" this content on your MacYou want it to sync so you can view this content on Penultimate In other words, sync penultimate across platform. I have a WACOM pen tablet attached to my keyboard all the time, so this is a very appealing idea. I tried this, and it looks like it doesn't sync changes back to Penultimate when I scribble something on my mac, save, and sync. Have you made any progress since you posted this?
