A Mac displaying a question mark folder on startup typically indicates an issue with the computer’s startup disk or system files. Here are some steps to address this problem:
- Check for Loose Cables: Ensure that all cables, including the SATA or SSD cable, are securely connected to the Mac. Sometimes, a loose connection can cause this problem.
- Reset NVRAM/PRAM: Resetting the NVRAM (Non-Volatile RAM) or PRAM (Parameter RAM) can help resolve startup issues. To do this, restart your Mac and hold down the Command + Option + P + R keys until you hear the startup chime a second time.
- Boot into Safe Mode: Try booting your Mac into Safe Mode by holding down the Shift key during startup. Safe Mode performs a basic check and can sometimes resolve disk-related issues.
- Run Disk Utility: Boot your Mac into Recovery Mode (hold down Command + R during startup), and then run Disk Utility. Use it to check and repair disk errors.
- Reinstall macOS: If Disk Utility doesn’t resolve the issue, you may need to reinstall macOS. This can be done from Recovery Mode as well.
- Check for Hardware Issues: If software solutions don’t work, there could be a hardware problem. The hard drive or SSD may be failing, or there might be an issue with the motherboard.
- Data Recovery: If you need to recover important data from the Mac and can’t repair the startup disk, consider professional data recovery services.
- Professional Help: If you’re not comfortable performing these steps yourself or if the issue persists, it’s advisable to seek professional assistance at a tech repair shop. They can diagnose the problem and provide appropriate solutions.
Remember to back up your important data regularly to prevent data loss in case of such issues.
