Buying a new MacBook is exciting, but the default macOS settings may not provide the best balance of privacy, security, battery life, and productivity. Whether you’ve purchased a MacBook Air or MacBook Pro, spending a few minutes adjusting key settings can significantly improve your experience.
This guide walks you through the first 10 macOS settings you should review after setting up your new MacBook in 2026.
