Compatibility: Make sure the protective case you choose matches your specific MacBook model, as different MacBook models may have different sizes and interface layouts.
Material: Hard plastic provides better impact resistance, while silicone is softer and can provide better slip and cushioning effects. Synthetic leather provides more stylish appearance options.
Design: Some protective cases may have additional features, such as improved heat dissipation, providing more interfaces, or built-in stands.
Brand and quality: Choose well-known brands and products with good reputations to ensure product quality and after-sales service.
