It does seem to be permission based, but I couldn’t find any way to fix it, even after resetting all my permissions in the console. I finally had to make a new user on my mac to solve it. I really hope I don’t run into this again. I really wish that Nuendo used a basic, mac based saving structure for all effects. Their whole mysterious black window thing is unnecessarily complex, obscure, and like I said… mysterious. I hate it. Where am I in this thing? Where am I saving? I hate it.
