Q: How can I successfully transfer Notebooks from the
Macintosh to Windows and vice versa? 

A: An easy way to transfer a Notebook between the Macintosh and
Windows platforms is through Apple File Exchange, an
application available on most Macintosh computers. Apple
File Exchange will transfer  end of line characters
appropriately. When converting a Macintosh Notebook to
Windows, select the Text Translation command under the Mac to
MS-DOS menu, and turn off the option to convert carriage
returns to carriage return-line feed.  When converting a
Windows Notebook to Macintosh, do the opposite: select the
option to convert carriage return/line feeds to carriage
returns.  All other tab and spacing options should be set to
Neither.

Besides this, there are a few things you can do to a Macintosh
Notebook before transferring to make the transfer come out
well. 

1. Apply the Uniform Style command under the Style menu to all
cells to eliminate font variation within cells.  Because the
Windows front end supports only one typeface per cell,
individual boldface or italicized words will cause the entire
cell to be rendered in boldface or italics.

2. Give the Macintosh Notebook a name that conforms to MS-DOS,
i.e., eight characters or less and ending in the .ma file
extension. (For example, change Favorite Plots to
favplots.ma.) The .ma file extension identifies it as a
Mathematica Notebook under Windows.

Some general facts to keep in mind when transferring
Mathematica Notebooks between platforms:

-  When transferring Notebooks between platforms, transfer
the .ma file only.  Information contained in .mb files  can only
be used by the same platform which created the file. Each
platform can create a new/appropriate .mb file from a .ma file.

- Fonts on individual computers will vary, and a transferred
Notebook may be rendered in fonts different from the original. 
If a computer renders output cells in a proportional-spaced
font, such as Times, change the output cell style to a
single-spaced font, such as Courier. Also, special
characters will not be the same in fonts on different operating
systems, and will have to be translated manually.  Two common
Macintosh symbols you should remove before converting a
Notebook are the em-dash (Shift-Option -) and the bullet
(Option-8).

-  Bitmap graphics are not compatible with foreign computer
systems. For this reason keep graphics in PostScript form.
Bitmap graphics can be converted to PostScript in Mathematica
with the Convert to PostScript command.

- Transfer duplicate files only.
