Application Uninstall
As a newer to Mac OS X, I don’t know how to uninstall a package as I did on the Windows. Someone may tell me to directly delete the app and it will be uninstalled, however, from my experience with Linux distributions, I feel that may not true. So, I did some research and found that there are a lot of methods about how to uninstall an application on Mac OS cleanly.
There is a free application named AppCleaner and a $7.99 AppDelete, I tried both and didn’t find any difference between them, so I choose the free one. Enjoy you Mac~
