You
are now done and your installation should be able to handle 
basic
LaTeX files. 
TeXShop is a regular Mac application and it is the only
application you
will be dealing with; it is both a 
text
editor and a
typesetter,
the latter meaning only that, when you want, it passes the source file
to 
gwTeX
for the 
LaTeX
source to be processed by 
pdflatex and then 
Mac OS X
(> 10.3) into a 
pdf
output file.
 TeXShop
should be
capable of immediately opening any 
basic LaTeX source file
which you can then
typeset by clicking on the 
Typeset button at the
top of the 
LaTeX source
file. Once 
TeXShop
has typeset a 
LaTeX
source file, 
TeXShop
displays the 
pdf output
file which you can
then print by clicking on the 
Print
button at the top of the 
pdf output
file or like any other 
Mac
OS X file. One very nice feature of 
TeXShop, by the way,
is that once 
TeXShop
has typeset a 
LaTeX
source file, it lets you go from any point in either the 
LaTeX source file
or the 
pdf output file to the corresponding point
in the 
other file.
In general, though, LaTeX files involve and require supplementary 
style sheets and 
RBA is no exception
in that regard. The necessary 
style
sheets are in the 
Complete RBA
Source (216.6MB), which is merely zipped to hold all the
files together You can also get 
Complete RBA
Source Compressed (16.5MB).
You need to
place these 
style sheets
in:
 
Users > Yourself
> Library > texmf > latex
*  Minimal that
it is, all of 
RBA
was done with this installation along with just a few
supplementary 
style
sheets … but with much 
help.
