I can't find a solution that seems to be what I want so I'll try here In our house we have a couple of MacBooks and a TimeCapsule. I have a load of photos and some iPhoto libraries on a USB HDD that I want to attach to the TimeCapsule USB port so that all the Macs can access the photos & libraries. Thats the simple bit. What I am trying to also do is make the USB secure or encrypted so that if it is stolen all the photos of my kids aren't wherever they shouldn't be etc etc.. It is formatted in the Mac OS Extended (Journaled). So how would I encrypt or make secure the USB HDD that also means I can access the files on both laptops (as long as we know the passwords or whatever) and if it gets pinched it is as good as a paperweight? many thanks for any help.
