Hi community, since a while, I have been experiencing a very slow battery charging on a MacBook5,2. Now, what's weird is that clicking on the battery icon reveals the "Repair battery" message. I guess both of these issues are linked in some way. Now, what I don't really understand is this battery has only 62 cycles on it, but only 73% health reported in Battery Health. How would I solve this issue, except buying a new battery, which doesn't make real sense here as the runtime is still decent? And since I installed Mavericks, all Preferences panes are locked. The problem being, my admin status from the previous Mountain Lion install wasn't transferred, and I am now on a Mac without an admin account. Is it common when installing Mavericks? How would I solve that, too?
