Steve Shoup

Almost every computer user have ever faced with loss of important info due to its removal, damage to the hard drive, formatting the data carrier, etc. The data on the computer should be treated carefully and responsibly. It seems we all know this, but this is not a rare situation when important documents or photos from the last vacation suddenly disappear from the device. It’s not easy to recover documents after a mechanical damage and if they were deleted a very long time ago. The faster you begin the recovery actions, the more chances you have to get your data back. You can find here information on how to restore your info on MAC.

 

Search in Trash

 

If the data were deleted recently and the trash has not been cleaned out, it is easy to return the data. On Mac, the Trash is located down most on the Dock panel. Physically, the trash holder is created as an invisible folder for each user. Until it is cleaned out (Empty Trash), the info from it can be restored. If deleting the document was the last action when de while Mac OS was in operation, then it can be returned by Command-Z combination. Using it you cancel the last action. The file will be returned even if the trash holder is closed. To return data, you are recommended to take the following steps:

 

  • open the Trash window by clicking on the icon;

 

  • find among the icons of remote files the necessary ones;

 

  • drag the document outside the trash holder.

 

Time Machine Function

 

The Mac OS developers have created a universal tool that can return any file ever existed in the operating system. Every hour Time Machine creates backup copies of all the changing data, including the operating system. The peculiarity of the program is that Once started, it automatically creates a full copy of the hard disk, which takes a long time. After that, every hour, it copies only those docs that have been changed. Thus, you can find the date of deleting or modifying the file in the program timeline, highlight it and click on the button to return. Prior to activating the program, no reservation is made.The interface is presented in the form of a flipping directory of backups, the timeline on the right and the main interface at the bottom of the screen. It is convenient to use; you can change absolutely everything back. But it takes a large space of hard disk or a removable storage media is needed.

Disk Drill has several powerful scanning techniques that can recover deleted files from the Mac, even from damaged disks. As an additional function, Recovery Vault (protection) allows the program to create backup copies, simplifying the recovery process.
