Time Machine comes installed on all Mac computers as part of its OS X operating system. Using Time Machine along with a backup destination such as an external hard drive, your Mac computer keeps a backup of the files on the computer, including Internet history. You can access the deleted files through Time Machine and permanently delete Internet history for better privacy. If Time Machine is turned off, the computer does not automatically keep a backup and deleted files cannot be recovered.
Creating Backups and Deleting History
Enable Time Machine
Things You'll Need
External hard drive, an Airport Time Capsule or an OS X server on the same network as the Mac
Determine the location of the backup for Time Machine. Appropriate destinations include an external hard drive, AirPort Time Capsule or a server on your network. If the drive or location is not already connected to the Mac, do this in advance.
The backup location must have sufficient space to hold the backup. Many Mac owners opt for a 1TB drive. Older snapshots are deleted when the drive is filled, to make room for newer, more relevant snapshots.
Open Finder on the Mac and click on Applications.
Scroll to Time Machine and open the application to begin. If you are not on the administrator account you will need to unlock Time Machine with the admin name and password.
Slide the switch to turn on Time Machine. You will be asked to choose a backup location. The first backup generally takes the longest.
After this, Time Machine can restore your Mac or individual files to a prior state based on date and time, if needed.
Find Deleted History on a Mac
To find deleted history on your Mac, locate the Time Machine icon, which resembles a clock, in the top right menu bar. The backup device must be connected to your Mac and turned on to access your backups. Click once on the Time Machine symbol to open the drop-down menu and choose Enter Time Machine. The Mac will connect to your backup location.
Browse through the backups and snapshots taken by Time Machine. These snapshots function like Finder on the Mac. You can click within each window to find the one you're looking for, such as Applications to find Safari for deleted history.
The snapshots have corresponding tick marks along the timeline with colors that indicate which snapshots are available. Pink or red tick marks represent snapshots that can be restored now from the backup. Gray tick marks are snapshots for which no backup is available.
Once you've found the intended snapshot, click on it to select it and click Restore.
