I have had my Macbook Air for a little over a year. I am a PC convert. On a PC I regularly defrag the drive, remove temporary files and periodically do some house keeping using a utility like CC cleaner. But I have no idea what to do when it comes to a Mac. Of late my Air seems to be running a little slow. Now when it wakes up from sleep it takes about 4-5 seconds before the touchpad becomes active, where as before it used to be instantaneous. A couple of times recently I have seen the spinning disc when doing certain things. I don't think I ever saw it until now. So I am thinking my Mac needs some cleanup of junk files, temporary files and such. I have installed and uninstalled a bunch of apps and for uninstalling, I have just dragged the application to trash because somebody told me that is all you need to do to delete applications and you don't have an 'uninstall' option like Windows. Is this the right way to uninstall apps? If not, what is the correct way? Also how do I clean up any junk files left over from the applications I have removed. In general are there any other housekeeping tips that will help make my Air zippy and like its old self again? I am still running Snow Leopard btw. Thanks!
