Hello! I have a quick question for any 13" mid-2010 MBP users of Yosemite. My laptop already drags its feet as its running a Core 2 Duo. It's not slow--but when you compare it to my iPhone or modern Macs, it's only average. My question to anyone that also has the same MacBook--did Yosemite cripple your computer's performance? With my iPad 2, iOS 7 took my iPad's speed from great to "meh." I wouldn't want the same to happen to my laptop. Thank you for your help!
