I'm probably going to cleanly reinstall my iMac, but I don't want to unless I can keep my preferences and my serials. Is there any way I can go about doing this? I have backup drive and incase that helps.
backup the home Library and root Library Preferences folder plus your home Library's Application Support folder. all your application and system prefs wil be backed up this way. some application serials may not be backed up so for those just do a reinstall.
I know that, but I kinda want the computer I had, but start anew. Without all the apps that I never used and the crap that slowed it down that I now hate. I want the serials and prefs just in case I might need them that's why.
