Hi guys! I've got a question regarding "Google Chrome Helper", it's taking up quite some RAM and it's not even responding. I'm getting a new macbook in 2 months but for the time being i still need to do some web development on my Mid-2010 MBP with 4GB of ram, which is at 99% capacity for most of the time. I'm running 10.10, but can someone explain me why i've got a lot of GCH that aren't responding? If downgrading from 10.10 to the latest Mavericks would benefit my performance i'm happy to do so (but how?). Hopefully someone can help me out, i'm quite annoyed with the current performance of my MBP.
