I have a shared (Win + Mac) external (SSD) drive with lots of paid and licensed NI content on it. It has been working fine all the time at home with Win. But now I am at the cottage with a Mac, and Native access shows a yellow exclamation point on all my libraries. It wants me to repair (implicitly downloading), but that is impossible as I am on an expensive and slow internet connection. Everything is on the ext ssd, 100s of gigs.
