I am using a 13" MacBook Pro on Snow Leopard with Safari 5.1.10 and this seems to be the last available update for the browser. Some of my regular visited web sites like google maps; flickr etc and updated an no longer support this ver for full use as before. Are there any other alternative browser ver that would work on my system to give me better use and viewing. Not sure if updating to a newer OS is possible with my system, see screen shot. Thanks for any help.
