C) Recover Data from macOS
Step 1: Back up the MacBook data [critical step]
This is critically important because if you reinstall the OS without first backing up the data, it will result in data loss due to overwriting. So, back up the data present in the Startup Disk to another functional Mac (Target Disk Mode), as follows:
Step I. Connect the Mac that has flashing question mark to another Mac via Target Disk Mode.
Step II. Easily get the Stellar’s data recovery software from the below:
Step III. Install Stellar Data Recovery Professional for Mac on the working Mac.
Step IV. Launch the tool, and from the main interface, select RecoverData.
Step V. Select the type of data and the location of the flashing question mark drive.
Step VI. Click Scan after you turn on the DeepScan feature for rigorous searching.
Step VII. Click Recover, and on the dialog box, specify the save location and click Save. The ‘save’ location can be the working Mac’s internal drive if it has sufficient space or else another external drive.
For quick walkthrough on how to use the software for MacBook data backup, see the following video:
Step 2: macOS Reinstallation
After the data stored on the HD – having flashing question mark folder problem – is backed up, proceed with reinstalling macOS, as follows:
- In the macOS Recovery mode, go to macOS Utilities and click Reinstall macOS.
- Click Continue then select Macintosh HD (Note: You have already done the Mac data recovery to an external storage drive.)
- Erase Macintosh HD and execute the on-screen steps to reinstall macOS. Once the installation is over, Mac automatically restarts and boots from the Startup Disk.
- In Setup Assistant, migrate your data from the source disk (i.e. external storage/HD of the functional Mac) to the internal Mac drive.
Note: When Disk Utility does not show the Startup Disk or cannot repair it, then the storage drive has hardware problems. Contact a Mac repair service provider in this scenario.

The second case happens when your Mac is stuck in the flashing folder with a question mark without booting. In this case, you need to enter the macOS recovery mode and reselect the Startup Disk. If it’s not visible, then try repairing it with Disk Utility.
If the Startup Disk repair fails, then you would need to reinstall macOS to overcome this problem. But, before that, it’s critical to back up the data stored on this hard drive, as reinstalling macOS will simply overwrite the existing data.
So, connect the affected Mac to a functional Mac via Target Disk Mode, install Stellar Data Recovery Professional software on this working Mac, and then run it on the affected hard drive to extract and backup all the data to a secure location. Once the data is backed up, reinstall the macOS on the drive to fix the flashing folder with a question mark issue on Mac.
