Hello I have read a lot online about how there were scrolling issues on the MacBook Pro retinas from 2012. Is there a verdict in on if it's till happening on the new MacBook pros? Specifically the 15 inch is what I'm interested in, but it'd be good to know the 13 inch is working fine too. I've been waiting to purchase till the whole freezing/boot camp issues got resolved. I'm just curious if I can still expect the scrolling issues I've read so much about. Thanks in advance!
