I have an old IBM Thinkpad Laptop running Windows XP. Right now, the battery doesn't work and it is really slow, plus, I'm not sure if it can use Wi-Fi. I want it to be able to use Wi-Fi, I want to make it run Mac OS X Lion (Permanently, NO PARALLELS DESKTOP OR VIRTUAL BOX.), and make it faster (new hard drive? more memory?). What are all the steps to do this?
