FCKEditor 2.6.5 using Firefox 3.5.2 & Safari on Mac Book Pro

I recently bought a Mac Book Pro. I'm using FCKEditor 2.6.5. It works on Safari and Firefox from my Mac Book Pro with the installed software running on a Linux Server. I'm developing on a Mac Book Pro and running locally and these 2 Browsers do not work. I'm getting these errors. I've narrowed it down to this statement in fckeditor.html:

LoadScript( 'js/fckeditorcode_' + sSuffix + '.js' ) ;

It never successfully does a write here:

function LoadScript( url )
{
document.write( '<scr' + 'ipt type="text/javascript" src="' + url + '"><\/scr' + 'ipt>' ) ;
}

I'm not able to tell why.
