I wouldn't buy a PC just so that you can take the Bar on computer. I think that my illegible handscrawl in conjunction with readable and brilliant essay headings was the only reason I passed! 
The bar exam prep people will teach you this in 3 years...
You may not need to take the "Baby Bar" (1st year student exam), depending on where you are going. Just be sure to register as a law student with the Bar in your first year and save yourself a bunch of 3d-year heartache.
Anyway, are you going to Boalt? Reasonably good Mac support, except for the software that some classes used for laptop final exams. Never made a difference to me, since I handwrote all of my exams. My Lombard got me through 3 years of law school, in style, and I don't see any reason why your vastly superior 12" shouldn't do the same. Regardless of where you are going, it's worth calling the school to ask about what computer set up they'd recommend... (which you can then ignore and use your Mac...)
best of luck
