我的是Macbook Pro 8,2版本。
刻光盘：用的是针对Mac修改的ISO。写优盘：写的也是针对Mac的ISO。因为文档说，在MacbookPro 8,2上，要把优盘和光盘都插上，然后从光盘安装的。试试只用光盘可以吗？

配置Wifi支持按这里的操作来做的：
There is no official support yet in Ubuntu 11.10, but you can get it working with the following repository:
sudo add-apt-repository ppa:mpodroid/mactel sudo apt-get update sudo apt-get install b43-fwcutter firmware-b43-installer
Then install the linux-backports-modules-cw-3.2-oneiric-generic or, if you have the pae kernel installed, the linux-backports-modules-cw-3.2-oneiric-generic-pae package.
Edit the /etc/modprobe.d/blacklist.conf and add the line:
blacklist ndiswrapper
Create or edit the file /etc/pm/config.d/modules and make sure the wireless modules (b43 and bcma) are blacklisted:
SUSPEND_MODULES="b43 bcma"
Reboot and the wireless should work.
这样安装linux-backports-modules-cw的时候会把内核从12.04原装的3.2.0-23升级到3.2.0-25，新内核下触摸板的三指和四指功能会失效。删除3.2.0-25内核，同时也删除了上面linux-backports-modules-cw，重启后三指和四指触摸功能恢复，而wifi仍然可以用，所以说安装内核模块这步不是必须的。
lm-sensors的sensors命令可以用来查看温度、风扇速度等。
