Here is how I did it (that's to prompt browser to download the csv file):

header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=file.csv');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
echo "\xEF\xBB\xBF"; // UTF-8 BOM
echo $csv_file_content;
exit();

The only thing it fixed UTF8 encoding problem in CSV preview when you hit space bar on Mac.. but not in Excel Mac 2008... don't know why
