Problem in installing litefilesystem.js

[sushmitacse]

Am using MAC OSX. when I am doing "sudo chown -R :www-data * " inside the src folder of litefilesystem.js its giving me a warning "chown: www-data: illegal group name" as a result of which my install.php is giving me a warning. And am not able to login to server.

www-data is the default group of the browser in ubuntu and other linux distributions.
Im not sure which one is the default group for XAMP on OSX, I think is daemon, try replacing www-data with daemon
