Issues on macOS can range from minor glitches to problems that prevent your Mac from booting altogether. A folder with a flashing question mark is one such case that appears on the screen during startup. It usually means that either the Mac is unable to locate its startup disk or it can’t detect a working macOS installation. As a result, the system is unable to complete the boot process.

Many factors, including startup disk issues like bad sectors, formatting errors, or directory corruption, can trigger this problem. Additionally, an incompatible or incorrectly installed macOS version can also cause the Mac to fail to start. Regardless of the reason, the error can interrupt your work and prevent you from accessing your files and apps. This guide will help you quickly fix the flashing folder with a question mark issue and get your system back on track.

Quick Ways to Fix the Flashing Question Mark Issue on Your Mac

If the error was caused by some minor software glitch, a simple restart can often resolve it. Next, check the peripheral devices like printers, scanners, or USB drives connected to your computer. Sometimes, they can interfere with the startup process and cause the flashing question mark folder issue on your Mac. Disconnect all external devices and check whether the error message disappears.

1. Check Startup Disk Settings

Make sure you are using the correct startup disk (usually named, Macintosh HD).

Click on the Apple menu and open System Settings.
Go to General > Startup Disk.

Select the startup disk that has your OS installed on it.

Restart your Mac and see if the issue is resolved.

If the issue still persists, move on to the next method.

2. Repair the Disk in Recovery Mode

A flashing folder with question mark issue can occur if your startup disk has run into errors or has become corrupted. Use the First Aid feature in Disk Utility to checks the drive for file-system errors. It repairs common issues like damaged directory structures, invalid volume headers, and minor metadata corruption on both APFS and HFS+ volumes. The best part is that this feature can also be accessed via Recovery Mode, useful when the Mac is unable to boot up.

Here’s how to boot into macOS Recovery:

For Apple Silicon Macs: Shut the Mac down completely. Press and hold the power button until you see “Loading startup options”. Click Options > Continue. Next, select Disk Utility and click Continue.

For Intel Macs: Restart while holding Command + R until the Apple logo appears. Your Mac will now boot into Recovery Mode. Select Disk Utility from the macOS Utilities window.

Once you have successfully accessed Disk Utility from Recovery Mode, the next step is to repair your disk using First Aid.

Select your startup disk (Macintosh HD) from the left sidebar and click First Aid.
Click Run and wait for the process to complete.

3. Reset NVRAM and SMC (Intel Macs Only)

Resetting NVRAM and SMC can help fix the flashing question mark folder by clearing corrupted system parameters which control how your Mac finds and powers its hardware components while booting up. Note that this method applies only to Intel Macs and it’s not possible to manually reset NVRAM and SMC on Apple Silicon Macs.

Note that this method applies only to Intel Macs and it’s not possible to manually reset NVRAM and SMC on Apple Silicon Macs.

To reset NVRAM

Shut down your Mac.
Press the power button and immediately press and hold the following keys: Option + Command + P + R
Hold the keys for about 20 seconds and then release.
Reconnect the drive after macOS has fully loaded.

To Reset the SMC (Intel laptops with T2 chips)

These steps are for Intel notebooks with a T2 chip. Intel notebooks without a T2 chip and Intel desktop Macs use a different key combination, so check Apple’s guidance for your specific model.

Shut down your Mac.
Hold Control + Option + Shift for about 7 seconds.
Without releasing them, press and hold the power button as well.
Hold for another 7 seconds.
Release everything and wait for a few seconds.
Power the Mac back on.

4. Reinstall macOS

When Disk Utility fails to resolve the issue, you’ll need to reinstall the macOS. Keep in mind that reinstalling will permanently erase any data stored on your computer. Therefore, use a Mac data recovery software to recover your important files first. To erase the startup disk, you need to boot your Mac into macOS Recovery using the steps outlined above.

Select Reinstall macOS and click Continue.

Select Reinstall macOS and click Continue.

Follow the on-screen instruction to complete the process.

5. Contact Apple Support

If the flashing question mark folder continues to appear even after trying all the troubleshooting methods above, the issue may be related to a hardware failure. In such cases, it’s best to seek professional help rather than trying to attempt further repairs yourself. You can contact Apple Support or visit and Apple authorized service provider to get your Mac properly diagnosed and repaired.

Wrapping Up

A flashing question mark folder isn't a sign of permanent data loss – it usually means your Mac can't find or read its startup disk. Work through the fixes in order: start with the Startup Disk settings, then move to First Aid, NVRAM/SMC resets, and reinstalling macOS only if the earlier steps don't work.
Since Disk Utility repairs and a macOS reinstall can wipe your drive, recover your files with a Mac data recovery software before you start troubleshooting, not after. If the issue persists through every method above, it's likely a hardware fault, and Apple Support is the right next step.
