Answer 1

I solved it finally. For your infor, I'm using php version is 5.4.3 and MAMP 2.2. Here are the changes:
1) Open php.ini
    Look for 'extension=php_fileinfo.dll' and remove ;
2) Download GNU file package for windows from http://gnuwin32.sourceforge.net/downlinks/file-bin-zip.php.
    Extract the zip file.
3)  Copy 2 file from the extract folder ../share/file/magic and ../share/file/magic.mgc and paste in folder php/extra/magic
     folder. (Create the magic folder as new folder).
4) Stop MAMP all services and start services again.
This will work for you !
