matlab r2013a安裝問題 - MAC

Your installation may require additional configuration steps.

1. The following products require a supported compiler:
MATLAB Coder 2.4

2. Simulink requires a C compiler for simulation acceleration,
model reference, and MATLAB Function Block capabilities.
It is recommended that you install a supported compiler on your machine.

3. To accelerate computations with the following products,
a supported compiler is required: Fixed-Point Designer 4.0

請問一下這要怎麼解決？才可以使用我的MATLAB@@???

對了我的是macbook air 2012 目前系統是最新的 也有安裝xcode5了


感謝各位大大
