My Macbook Pro has gotten a bit slow over the years, and as it was still running on Mountain lion I decided to do a clean install. I've been going through all the waste on my computer and threw away everything I didnt want anymore. Then I made a backup of my computer. I installed Mavericks on a bootdisk of 8gb and I'm all ready to go. However, I still have a question: - I want to make a clean install of Mavericks on my mac, and restore my data through the backup I've made in Mountain Lion. However I don't want all the system & library files to be restored. The reason that I think my macbook has gotten slow is because it has been building up files by installing and deleting apps over the years. Is there a way to only restore certain parts of the backup?
