The "?" symbol displayed when you start up your MacBook Air indicates that the computer cannot find a valid startup disk or system software. This could be due to a few different reasons, such as a failed system update, a corrupt hard drive, or a damaged startup disk.
Here are a few troubleshooting steps you can try to resolve this issue:
1. Reset your MacBook Air's NVRAM (non-volatile random-access memory) by holding down the Option, Command, P, and R keys immediately after pressing the power button. Keep holding these keys until you hear the startup sound twice, then release them.
2. Try starting up your MacBook Air in Safe Mode by holding down the Shift key immediately after pressing the power button. This will start up your computer with only the essential system software and drivers, which can help identify and resolve any issues.
3. Use Disk Utility to check your hard drive for errors and repair any issues. To do this, restart your MacBook Air and hold down the Command and R keys to enter Recovery Mode. From there, select Disk Utility and follow the on-screen instructions.
4. If none of these steps work, you may need to reinstall macOS on your MacBook Air. You can do this by entering Recovery Mode and selecting "Reinstall macOS" from the menu.
If you continue to experience issues, it may be a hardware problem and you should consider contacting Apple Support or taking your MacBook Air to an authorized service provider for further assistance.
