Before you learn how to recover deleted data on Mac OS X, it's important to understand what deleting a file means. When you delete a file, the operating system only removes the entry – not the contents of the file. This means that the space is now free to be used for new data, which is why your files are often irretrievable after deletion.
If this happens, and you find that you have accidentally deleted some important files, there are steps you can take to recover them.
First of all, do not write any new data to the hard drive or device from which you have lost data. Ideally, do not use the disk or device at all. Next, you may consider using a professional Mac Data Recovery Software, which is compatible with Mac OS X, to retrieve your deleted data.
Here comes the good news: powerful Mac Data Recovery software - Mac Data Recovery Wizard is at your service. It can easily help you to recover deleted data from Mac OS X. Generally, it involves two steps: scanning the disk/drive to locate lost files - and recovering/exporting the restorable data.
Next, let's go through a detailed guide.
Step 1: Scan for the deleted files
Select the hard drive, external drive, or SSD from where you lost important data and files, then click “Find Lost Files.”
Step 2: Scanning for Lost Files
The software will scan the selected volume quickly and thoroughly, trying to find as many deleted files as possible. Filter the required files by Type and Path options.
Step 3: Recover the deleted files
