I got my new 2.6ghz 256GB 13" rMBP today. Took it out of the box, restored from time machine, everything hunky dory except.... The battery cycle is on 3, and I've not plugged it in for its first charge yet. Is that normal?! On a side note, the menu bar seems to disappear from the top of the screen each time I quit an app, but as soon as I click into anything else it comes back. Assume this is a software related issue?!
