I just started to use Time Machine with my new Mac. It has been saving the backups to the new 2 TB external disk I just got. However, today when I went to look at my disk usage on SSD, it says I have 100 GB worth of backups on the computer. First off, why would anyone backup anything onto the drive that needs to be backed up (if that even makes sense?) Second, how do I delete the backups? I used MacKeeper to try and see where there was 100 GB of anything on my drive and it doesn't show anything. Thanks for the help!
