I have a 3 years + account backed up onto time machine, and i'm deciding whether to use migration assistant to transfer my data onto my new mac. The problem is, my old mac had LOTS of disk permission problems, often requiring hours to resolve, and would periodically show up every few weeks. Will migration assistant "transfer" those problems onto my new mac? If so, how much data (or which categories) can i transfer without getting those problems? and would it make my new mac slower? Will copying anything from my old account somehow bring permission problems to my new account? To elaborate, i'm interested in bringing over some application support files/settings for apps like skype(chat history), chrome(dozens of custom search engines), etc.
