I have a cheater... he always deletes all the safari history after using the computer. is there a way to still find that within the computer? any help is appreciated. Thank you
Yes. You can get it back from your Time Machine backups. Just look in the user folder in one of the Time Machine backups of your choice. It's in the Users/Library/Safari/History.plist. Restore that file to the desktop and put it into the Safari folder. You can go back to any date in the TM backup and get the history from that time.
