In your first message (with the old version of Sage) you had:
students-MacBook-Pro:~ student$ /Users/student/sage/sage/sage
It should look like this. In your more recent message (with a good version
of Sage), though, you had:
students-MacBook-Pro:~ student$
/Volumes/sage-7.2.beta0-OSX_10.11.4-x86_64/SageMath/sage ; exit;
The part "/Volumes/..." indicates that you dragged the "sage" file from the
disk image to "Terminal", not the "sage" file from the copied version. Make
sure you use "sage" from the copied version. It might be safest to first
copy "SageMath" (as you have done) and then eject the disk image. Then
proceed to drag the "sage" file to "Terminal".
