&gt;<i>Can anyone comment if the GM fixes the battery problems Beta 1 had? I was on the first beta awhile back, and my 2012 rMBP got about an hour battery life (I usually get closer to ~3-4) and was always hot to the touch.</i><p>Those are usually no battery or power management related problems, but &quot;rogue program eating too much CPU&quot; problems.<p>Usually it&#x27;s Spotlight, but a look in Activity Monitor would have shown the culprit.
