I did a clean install on my iMac. Now I cannot access my backups. I can see the time capsule, but when I open time machine, I only have today which is the newly installed system. I am now trying to use migration assistant to grab my files. I got to where I choose my time machine and entered my password. Now I don't see any action. How long will the transfer take? My 500 gb time capsule is full. Should I be seeing something on my screen.
