Alright, hope i'm In the right place, if not, my apologies. So I just bought a New MBP (non retina) and the first thing I did was put my ssd from my old macbook in. This is where I started having problems. on my old system, I never had any issues running this ssd, but for some reason in the mbp it stutters and lags to the point it's unusable. I have reinstalled osx many times now, and have zero-ed out the drive. Nothing seems to change the performance. I am led to believe this is now a trim issue. they only thing I am getting caught up on, however, is why did it work fine in the old macbook without any trim support? Old Mac- Late-2009 Macbook Unibody. New Mac- late 2012 Macbook pro 13". ssd is a crucial, unknown model I appreciate any help, i have spent hours googling and trying to figure this out. Thanks!
