I'm not familiar with the ideal process on reinstalling Mavericks on my computer. There are a lot of tutorials online and I'm not sure which one is the best to follow. Wondering if you guys could help me out. I have a 15" retina macbook pro, late 2012. A few concerns that I would like to have answered if possible. 1. Will reinstalling from a USB keep my recovery partition intact? 2. Should I deauthorize my computer from iTunes before doing anything? 3. I have a backup on my 1TB external, can I pick and choose what I want back in my computer after I reinstall? 4. Is this a good tutorial on creating a Mavericks USB drive? LifeHacker 5. I have 1Password with iCloud backups. Will I have any issues with 1Password after the reinstall? Is there something I should do before starting? 6. Will reinstalling affect my syncing and backups with my iPhone and iPad? Are there things you have run into that you wish you would have known/done before reinstalling that would be good to know now? I know this is asking a lot but I just don't want to mess anything up. If you don't feel like answering any questions, is there another thread that would be helpful that I might have missed? I appreciate any help that I can get. Thank you.
