Understanding the Flashing Folder: What’s Going On?
The flashing folder with a question mark indicates that your MacBook Air can’t find a bootable operating system. This could be due to a variety of factors, including:

- Incorrect Boot Settings: Sometimes, your boot settings might be configured incorrectly, causing your MacBook Air to search for a non-existent operating system.
- External Drive Issues: If you’ve connected an external drive and set it as your primary boot drive, a problem with that drive can lead to the flashing folder.
Troubleshooting Steps: A Step-by-Step Guide
The following steps provide a systematic approach to troubleshooting and fixing the flashing folder issue:
1. Restart Your MacBook Air
The simplest solution often works! Restarting your MacBook Air can sometimes resolve temporary glitches that might be causing the issue. To restart, press and hold the power button until the “Slide to Power Off” slider appears. Slide the slider to shut down your computer, then press the power button again to turn it back on.
2. Check for External Devices
If you have any external devices connected to your MacBook Air, disconnect them. This includes external hard drives, USB drives, printers, and any other peripherals. Sometimes, these devices can interfere with the boot process.
3. Reset the SMC (System Management Controller)
The SMC controls various hardware functions, including power management. Resetting the SMC can sometimes resolve boot issues. Here’s how to do it:
- For MacBook Air models with a MagSafe power adapter:

2. Turn it back on, and immediately press and hold the Shift key.
3. Release the Shift key when you see the Apple logo.
4. If you see the login window, you’ve successfully booted into Safe Mode.
If your MacBook Air boots successfully in Safe Mode, it indicates that a third-party application or extension might be causing the issue. You can try to identify and uninstall the problematic software.
