Since the day I got my new macbook pro, I was trying to make it as similar as it can be like windows. I use a show desktop a lot on my windows vista laptop. This is reason I want to implement show desktop in mac too. After some googling I came to know about this cool application called show desktop for mac which allows you to implement show desktop functionality like windows.
This is how it will look like after you add it to the dock on your mac
Here is how you can install this simple application on your mac
You just need to drag and drop Show Desktop Icon as highlighted in the above image to your applications folder on your mac or directly to the dock.
