How to Recover Your Mac Data If There Are No Available Backups

As mentioned above, before you delete a Time Machine backup, you need to make sure that it is needless. But it is still possible that you delete some important Time Machine backups by mistake. If so, how to recover your lost and deleted Mac files if there are no available Time Machine backups?

You can choose to use professional Mac data recovery software. Here, you can try Stellar Data Recovery for Mac.

This software is specially designed to restore your lost and deleted files on a Mac computer. As long as the files are not overwritten by new data, this software can work to get them back. Besides, it can recover various kinds of files like images, videos, documents, music files, and more from multiple data storage devices including internal hard drives, external hard drives, SSDs, SD cards, memory cards, pen drives, etc.

More importantly, this software can work in different situations. For example, when your Mac won’t turn on, you can use the boot edition of this software to rescue your files if necessary. Or, if your MacBook Pro boots into a black screen or white screen, this software can also work to rescue your Mac data.

If it is the first time for you to use this software and you are not sure whether this software can find the files you want to restore, you can first try the trial edition of this software.

This free tool allows you to scan the drive you want to recover data from and shows you the scan results. If you can find your needed files from the scan results, you can upgrade this software to a full edition and then recover all your needed files to a suitable location without limits.

You can go to the MiniTool official download center to download the trial edition and then install it on your Mac computer.

Then, we will show you how to use this software to recover your lost and deleted Mac files:

1. Open Stellar Data Recovery for Mac.

2. You will see the Select What To Recover In this interface, you can select the data types you want to recover if necessary. If you want to recover all types of files, you just need to make sure that the button for Recover Everything is turned on.

3. Click the Next button to continue.

4. The software will show you all the drives it can detect. You need to select the one you want to recover files from and then click the Scan button to start the scanning process. Here, you need to know that the Deep Scan button is turned off by default. If you need to perform a deep scan, you need to manually turn on the button.

5. This software will take a while to finish the whole scanning process. To guarantee the data recovery effect, you need to wait patiently until the entire process ends. When the scanning ends, you can see the scan results that are sorted by Classic List by default. You can unfold each folder to find the files you want to recover.

Of course, you can also use the other two features, File List and Deleted List, to find your needed files. For example, if you only need to recover your deleted files, you can switch to Deleted List to find them.

6. This software also allows you to preview files in the scan results. You can double-click one file to preview it and check whether it is the file you want to retrieve.

If you discover that this software can find your needed files, you can upgrade it to a full edition and then select a proper folder to save them. The destination folder should not be the original folder. Otherwise, the deleted files might be overwritten and become unrecoverable.
