注意：2011年MacBook Air的USB是2.0版本，使用的是EHCI和OHCI驱动，而2014年MacBook Air是USB 3.0版本，使用的是xHCI驱动。我最初编译内核是在2014年的MacBook Air 13上，同样的配置在2011年MacBook Air 11上需要修改USB驱动选项（或者都编译成模块方式），否则会导致键盘无法使用（键盘是通过USB驱动）。

驱动
使用Apple USB以太网卡是AXIS网卡，需要编译支持
重启系统
exit
cd
umount -l /mnt/gentoo/dev{/shm,/pts,}
umount /mnt/gentoo{/boot,/sys,/proc,}
reboot
触摸板
MacBook的触摸板非常灵敏，并且支持tap to click（也就是轻触等同于点击），非常方便使用。不过，默认在X Window下没有启用这个功能，导致非常不习惯。
TapButton(number) sets the mouse event to trigger when you tap your trackpad with (number)fingers. "0" means disabled, "1" means left-click, "2" means middle-click, "3" means right-click.
即，单指轻触是左键，双指轻触是中键，三指轻触是右键
另外，发现键盘输入的时候，手掌很容易碰到触摸板导致鼠标漂移输入混乱。
