Is there a way to download a Time Capsule firmware update from Apple and store it directly on a Macbook Pro as a file, namely 7.6? The available TC firmware upgrade downloads on the Apple site are 7.6, and 7.6.1. Some users have had idevice connection issues with 7.6.1, so I would prefer to have 7.6 available as a fallback. The Airport utility shows the 7.6.1 upgrade only. My third gen TC has the original 7.5.1 it came with. Why would Apple show 7.6 as available if there's no way to get it?
