There is something confusing me with my Carbon Copy Cloner. I backed up my Macintosh HD yesterday and today I installed Opera Web browser. And then after I decided to restore the Carbon Copy Cloner image from yesterday. So I then rebooted my Mac and selected to boot from the USB Hard Drive where my Carbon Copy Cloner image from yesterday resides, but when I loaded the Carbon Copy Cloner image from my external Hard drive, and type opera in the Finder, it says OPERA TODAY is listed! But how can that be when I never installed Opera on the image from yesterday? And when I type Opera into Spotlight, it also shows up there! But HOW and WHY? If I booting into an image yesterday, how can Opera have copied itself over to my image?
