I've been installing various freeware apps just to see what it does and the ones I choose not to keep I drag it to the trash to uninstall. For example, this morning I was trying to find something to play a .wmv file (VLC won't). I know about flip4mac, but a lot of people say is slow cause its not a UB yet. So I found someone on another mac forum that said divx player would, that it played every kind of file he had tried. So I download the install pack, install it, open the .wmv and it won't play. So I drag the divx app to the trash. When I would do a fresh install of XP on my computer I was always reaaly picky about what I put on initially. Cause over time installing/uninstalling stuff would cause the system to lag. So in the example above I would cringe if I installed/uninstalled something fresh off a reformat/reinstall and it didn't work properly. (My mini is 2 weeks new, so essentially I'm looking at in the same way as a fresh install of XP) This kind of thing (system lag) doesn't happen with a mac right? I've seen people confirm this, that a mac doesn't have a registry to get corrupted like an MS OS, but I just wanna make sure. I don't wanna be installing things willy nilly if its gonna cause problems down the road. When I uninstall an app on the mac, all traces of the program are gone? Nothing left hanging around to give me any problems later on? And is it simply as easy as just dragging that icon from the apps folder to the trash? That gets rid of everything? I know I'm probably worrying over nothing, as I have it in the back of my mind that all the install/uninstall won't bog the mac down, but old habits/fears dies hard. Thanks.
