If it says Core 2 Duo, then it is 64bit ignore the 32bit kernel issue, it will run 64bit software just fine. Physically, if your MBP has a black keyboard, it is absolutely 64bit. The original MBPs had a silver keyboard and the 32bit units were all but replaced in early So if you purchased your model even in the later course of , then it is a Mac capable of running 64bit.

Also, if you are running Lion, then you are 64bit as Lion does not run on 32bit Macs. Paul Lefebvre Paul Lefebvre 2 2 silver badges 5 5 bronze badges. System Profiler isn't installed on my machine—or Spotlight can't find it—so this answer won't work for everyone.
