I used migration assistant to use my old time machine backup to restore all of my items on my new iMac. All of my info was transferred over no problem. The issue started when I realized I only have 85gb left on my backup drive when on my old computer I had well over 300gb. When I tried to enter time machine to see what all was on there, I can not view ANY older backups, not even ones that have been done on my new computer since i had it hooked up. It appears they are all there (there are dates back to 2009) but all of the finder windows are black and I can not see any information on them. does anyone have any ideas? It worked perfectly fine on my old computer. Did I somehow miss a step after migration assistant did its thing? I would REALLY like to have those old backups available.
