My Mac Software List 2 - software installation, system

Continue with my software list. Many mac newbees want to ask: how do I install/un-install a program? Where is the install/uninstall window in mac? The simple solution: drag your application to your Application folder when install it, and move it to the Trash when uninstall it. This solve 95% of the problem. Hard to believe? Yes! That is how most applications work on a mac, which is also called "green installation" on a windows PC. There are few exceptions:

1. Some application does involve a installer, like the .exe file you need to click on a windows machine. For example, our favorite statistics software, R. Just follow the instructions, select a Volumn (meaning, partition, most of the time, just your current hard drive) to install, and a stand alone application will appear in your application folder. Un-install just trash the file in Application folder.
2. Some plugin needs you to execute. For example, adobe flash web brower plugin when you run for the first time. Just click it, and do not worry where it goes. Un-install gets trickier, but most of the time, you do not need to uninstall.
3. Dashboard widgets. Install, click it, and choose keep it in the dashboard. Un-install, click the plus icon on the bottom left of your dashboard, and choose the widgets widget to un-install. You cannot un-install the build in widgets this way, and there are other ways to do it.
   
4. System preference plugin, for example, the famous Growl notification. Click install most of the time, and it will appear in the bottem line of your system preference panel. Right click (option click or two fingure tap click) the icon on the sysstem preference panel to un-install.
5. Other plugins. Typically, you need to manually move it to a specific folder. Un-install means trash it from that specific folder. This is every un-intuitive. Fortunately, you may not even encouter this problem if you are not an advanced user.

Having said that, I do want to mention a shareware for un-installing the programs/plugins:
 AppZapper, shareware
Only downside is the price, but still resonable. However, you don't have to own it unless you are a control freak like me. As I said, I would like to tune every aspect of my computer, so I also own following sharewear. I got them from bundle sales, and they are pretty good (except for the price), and I would probablity not purchase them separately at full retail price.
 MacPilot, shareware
System tuning/optimizing program. Don't think you need it with a new mac.
 Xslimmer, shareware
Slim you universal binary program to ppc/intel only, and trim extra language packs. I need it because the hard drive on my old powerbook is so small... but not recommended for new macs, you have a big hard drive!
