Have you ever faced problem in downloading a ZIP format file using MAC browser? Well we certainly have, let me elaborate the problems with ZIP archives.
There are many libraries available in PHP for manipulating the ZIP format archives. Zip archives created using these libraries works fine under Windows and Unix browsers but has serious problems on the Mac browser.
PclZip is a PHP class that can extract or create ZIP format archives. This class supports relative paths/no paths, comments and recursion through subdirectories.
To solve this hitch in Mac browsers , redirect to the ZIP archive after creating the archive using PclZip library instead of sending the file to the browser for download.

Safari and Opera have a loyal band of followers.
There is quite a lot of users still on IE 6 – Slow move to Vista could be the reason.
Firefox dominates the market – Mix of 2.x and 3.x
Chrome is catching up – Gears would help improve on that score. Disappearing links and download hassles need to be fixed.
There is always the need to build browser compatible websites

There has been cross talk about Microsoft releasing IE 7 for Mac.
IE 5.2 for Mac is every web developers nightmare when it comes to browser compliance and web standards. Microsoft itself recommends Apple Safari
Being an ardent Mac fan since the early 90's, our office Mac which is being shared my many users gets it due respect and care. There is quite nothing like it when it comes to usability. Many of us use safari on our XP desktop for the same user experience.
Leopard is here
We have a group of techies out here who loves the MacOS platform – an icon of usability. The public beta Safari browser is now available for Windows XP The rendering is excellent and does not pose much of browser compatibility problems for IE websites.
