I have a highly number of applications. Some important, some not, but nevertheless a big collection. The purpose of this thread is my concern over certain apps such as 1Password and the like. See, what's on my mind is when it comes time to install snow leopard, these kinds of apps will need to be reset or need the activation password again. The reason i'm not too fond of this is that 1Password was a free app on the "macheist.com" website and 1Password, along with other applications are some of my most used/valued apps. I guess what i'm wondering is (& this is in accordance with today's new info re: snow leopard installation) what options i'll have when it comes time to install. See, running Leopard for the past few years and even once accidentally deleting a couple of system folders I shouldn't have been messing with; I get the feeling my Leopard Macbook isn't up to par as it once was. Therefore would like the option to do something like a clean & install feature, where I'd like for Leopard to kinda "reinstall" to its original state (hopefully adding w/e system files I once deleted months ago.) I mean, I don't even have the original "DVD Player" application anymore and what kills me is I don't know why! So when a kind of "clean & re-install" feature happens, i'm guessing it would erase everything on my Mac...but everything as in Leopard too? Cause i'm guessing the Snow Leopard disc won't include "Leopard" itself and Snow Leopard is really just an "add-on" to my already installed Leopard right? I'm not too sure but... ...but, the main end I want to reach is making sure that Snow Leopard has a solid foundation of Leopard, which I believe isn't its best as it once originally was. Along with making sure some of my apps retain their original state, not forcing me through a headache attempting to retrieve an activation code from macheist.com which i'm sure would be unavailable since it was the MacHeist version of 1Password. That and of course the other little things like, making sure I still have my 10GB collection of iTunes music if Snow Leopard cleans and re-installs or w/e. My apologies if the lingo of this thread isn't the level it should be, i'm not new to Macs or OS X but def. new to this subject matter. Thanks!
