About upgrade Windows 10 to Windows 11 on Mac via boot camp, it carries some risk, but it's generally manageable if you're prepared. Your MacBook Air is technically capable, but you're navigating unsupported territory, which always introduces potential issues.

• Download Windows Support Software: While in macOS, open Boot Camp Assistant, go to Action -> Download Windows Support Software, and save it to a USB drive. These are the drivers you may need to reinstall after the upgrade.
