The first step is to download the free Disk Drill application from our website. It requires Mac OS X 10.8.5 or later. After downloading, find the "diskdrill.dmg" file in your Downloads folder and double-click on it. Drag the Disk Drill icon to your Applications folder when prompted.
Disk Drill ensures the safety of your files. Recovery Vault and Guaranteed Recovery options keep your files protected and safe before something is merely happening. You'll never need to recover deleted files on Mac! Recovery Vault puts together a special map for Disk Drill to locate deleted files and Guaranteed Recovery creates invisible copies of the files when those are moved to Trash. All of it ensures the integrity and safety of your important data.
Even when you find yourself in a situation that seems hopeless, Disk Drill will still do its very best to save the day. Disk Drill's Deep Scan digs into core file structure and seeks for file signatures that are still there somewhere just not as easily recognizable and puts the pieces together to restore the files. The more known signatures are discovered the easier it gets to recover deleted Mac files of various types including XLS, DOC, AVI, MP4, JPG.
