When your Mac is having a hard time finding a bootable operating system, what it usually does is it displays the flashing question mark on your screen. It’s your Mac’s way of crying out for help.
In most cases, your Mac boots quickly enough that you will never notice the flashing question mark. Then again, there are instances when you find the dreaded icon, either for a short time before finishing the startup process or it just appears stuck, waiting for you to do something.
Here’s what you should know to find a solution to the problem: While the icon is flashing on your screen, your Mac is actually checking your system for any available disk it can use to boot your OS. If it finds one, the startup process is completed. That’s it. Otherwise, you should take action.
Don’t worry because we’ll teach you how to fix a Mac with the dreaded flashing question mark. Although there are many ways on how to get rid of the flashing folder with the question mark, we’ve only listed the easiest methods. Check them out:
1. Use your Mac in Recovery mode.
If you are trying to boot your Mac using its internal drive, you need to shut it down first by holding down the Power button. When you start it up, hold the CMD and R keys until the Apple logo appears. This should start your Mac in recovery mode.
After this, go to the Apple menu and select a new startup disk from the Startup Disk option. Once you have selected a new disk, restart your Mac so that the changes will take effect.
2. Repair your Mac’s startup disk.
If your Mac cannot detect your startup drive, go to the macOS Utilities window and open Disk Utility. Select your startup drive and navigate to the First Aid tab. Click Run.
Once the repair is successful, go back to the Apple menu and select the newly repaired disk under Startup Disk. Finally, restart your Mac.
In the event that your Mac fails to repair the disk, you have to erase the disk and reinstall macOS. But before you do that, have a backup of your data. If you already have a Time Machine backup, you can proceed by going to Utilities -> Time Machine Backup. From here, click Restore.
If you don’t have a backup yet, make a new one by following the steps below:
- Plug an external drive to your Mac.
- Open Disk Utility.
- Go to the Erase tab and erase the contents of the external drive.
- Next, go to the Utilities window and click Reinstall macOS.
- Follow the steps and wait for your Mac to restart.
- Once you see the Setup Assistant, click on the migrate data from another Disk
- Select the regular startup disk of your Mac.
- Wait for the setup process to be completed.
- Once it is done, check if your data is already on the external drive.
Now that you already have a backup of your files and data, you may delete your Mac’s regular startup drive under Disk Utility. Boot your Mac in recovery mode. From the external disk, select Reinstall macOS and choose your Mac’s original startup disk. As soon as your Mac has restarted, select the migrate data from another disk option again, but this time, select your new external drive as the data source. You should now have an installation of macOS on your startup drive.
3. Seek help from an Apple Genius.
