Okay, so I know that to uninstall an application, you go to the Finder > Applications > drag the icon into the trash. Apparently some applications leave some traces, and you're supposed to go to the Finder again and search for the name of the application etc. and delete any other tracers. I've downloaded and installed/uninstalled only a couple of applications so far. I installed Google Chrome as a test uninstall. Removed it from Applications, then did the search through Finder to attempt to find any other files. I couldn't find anything, so presumed that was that. Reinstalled Chrome, because I use it anyway. I downloaded iProcrastinate from the Mac App Store and didn't really like it, so removed it the same way as I had done with Chrome. Did a search through Finder for iProcrastinate after I had deleted it, and couldn't find anything. Now, I'm confused, because I thought there would be some traces left from both of these applications? Also, is simply deleting the application from Applications enough for it to be uninstalled? Since my Mac is new, and I've never had one before, I don't particularly want to be messing about with files and ending up deleting something accidentally that I actually need.
