Plenty of people here build Sage on Macs. OS X 10.7 is not supported, but
10.6.7 should be. I don't know if there are significant differences between
Mac OS X 10.6.7 and Mac OS X Server

Those lists aren't the same. (1/4)*pi + 1 is equal to (pi+4)/4, not
5*pi/4. So I sure hope there's no way to simplify your first list into
your second one. If I add in one more term at beginning so that Sage can
tell what the difference is between consecutive terms, I get something
perhaps
Note that 439+584 = 1023 = 2^10-1, so -439 and 584 are congruent mod
M=2^10-1. (While B, M, and N are integers, x is element of Z/MZ, so
comparisons like x==B are done mod M. Any printing of numbers involving x
are done mod M.)

Instead of using jsMath, you could type latex(a) to get the LaTeX code for
the object a. Then you can paste it into a LaTeX document and edit it as
you please for viewing or printing.
Or you can do this:
sage: from sage.misc.latex import _latex_file_

It shouldn't be too much faster once Maxima is started up - the first
integral will be longer because the Maxima library has to initialize,
