Concerns about transferring data over to my new Mac
So recently I purchased a new MacBook Pro and I am in the process of transferring over all of the many specific files on my old laptop to my new one. I don't want to transfer all of the data on my old computer, just the specific stuff that I want. I need to ship back the old computer soon though to Apple because I am getting credit for exchanging it and I'll I am running low on time. I have created a backup of my old computer using Time Machine, however, I am still nervous about wiping it and shipping it back before I am absolutely positive that I have gotten everything I need currently over to my new computer through file sharing or will be able to access it through Time Machine on my new laptop at a later date. Is there anything else other than the stuff I will be able to access from a Time Machine backup that is worth transferring over to my new computer before wiping my old one? Stuff like passwords, message history, app settings and preferences, fonts, etc? My worst fear is shipping back my old laptop and realizing that the time machine backup is missing important files.
