Hey, MacRumors developers! I was wondering if any developers out there on the forums was running Mavericks on either an early '11 or late '11 MBP 15's. We have these two machines in the house with i7's and I was wondering about the beta's performance on those machines, most specifically how battery life is holding up. I understand Mavs was released only yesterday and it will take time to monitor performance on these machines, but I thought I'd open up a thread to help those out with these machines as well. Thanks, developers!
