Data Recovery on macOS: Why We Need It Here
While performing macOS upgrade or fresh installation, you must back up data to an external storage medium. Backup helps to restore all the data back to Mac's internal storage drive, containing the new macOS. If you do not have a backup, then you end up losing all your data stored in the Mac drive. This is because, during macOS installation, the installer erases the startup partition completely or the entire storage drive, depending upon your choice during installation.
If No Backup: What Is the Recourse?
There are chances that you did not take backup to an external backup drive, or in the rare case, the backup itself was lost, damaged, or unavailable. In such scenarios, you can rely on a data recovery software—such as the editor's choice Stellar Data Recovery Professional for Mac—that can recover your lost data after macOS Mojave installation. The software works flawlessly with the older & newer version of MacBook Pro, MacBook Air, iMac, iMac Pro, and Mac Mini etc.
The Process of Data Recovery
The process of data recovery is straightforward. Follow the steps mentioned below to get back the data stored in the drive—erased completely after installing the new macOS Mojave:
1. Download and install the Mac data recovery utility on the same system where you have installed the new macOS Mojave (due to the negligible storage requirement of the utility).
2. Alternately, you can download and install the utility on a different Mac machine, then connect the internal drive as an external device by removing it from the affected Mac.
3. Launch the data recovery software to interact with its lucid graphical user interface.
4. In the Recover Data module, select the type of data and the location of the storage drive.
5. Toggle on the Deep Scan switch from the bottom left and click the Scan
6. Allow the scan to complete, which may take some time—depending on the storage size and the condition of the affected drive.
7. Preview the recoverable files if you want, then select all the required files and click the Recover
8. Specify a different external backup drive with size greater than the drive where you are performing the data recovery then click Save.
When the save process is complete, verify the recovered data from the backup storage drive. Copy the files back to your Mac or an externally used Mac drive (reconnect the drive to the Mac once the restoration process is over).
Activation of the Software
You must activate Stellar Data Recovery Professional on your Mac in order to save the recoverable files. The free download version of the software is a good way to know the software's interface, scan your drive, and preview the recoverable files.
