The Mac issue revolves around the software we take our exams on: ExamSoft. In the past, ExamSoft was strictly a PC-only application, but this year they added Mac support (regardless of Windows I believe). BC, like many law schools, is risk averse and decided against allowing students to take exams on Macs this year because of any potential bugs that might pop up and cause problems in the first year of widespread use. It also would have meant additional cost in the form of tech support for Macs in addition to PCs (IT people are running the halls on-call during exams in case a student's computer crashes).
Since I haven't heard of any big problems at other law schools from ExamSoft on Macs this past fall, I wouldn't be surprised if a number of schools revisited their policy for next year.
All of this said, I'm a Mac user at BC and have been able to get by fine. In another thread I laid out the three options for Mac users at BC during exams:
1) Have a PC on Standby: I borrowed my wife's old computer for exams. Other folks snatched cpu's from friends, roommates, or family. A fair number also just kept their undergrad PC and upgraded to a Mac for law school.
2) Rent a Laptop from the School: The reported cost for picking up a laptop for the exam period was $200/semester. It was a little hair-raising for some folks when they had to pick up the laptop on the day of the exam, and in some cases, were almost late to the exam after waiting in line.
3) Signup for a Computer in the Library Lab: Students have the option at no charge of signing up for a desktop computer in the library's computer lab. There was plenty of space this past semester in the computer labs for students who wished to take their exam there. Some even preferred this atmosphere since there were less people around.
