I have a mid 2010 MBP that has been nice and fast for most of it's life. It was upgraded with a 750gb HD with built in SSD,(pretty fancy for the time) that helped with boot up a few years ago. It's also maxed out on ram. It doesn't get as much use as it used to but I'd rather not relegate it to the graveyard yet. I've already cleaned the junk off the drive and that didn't do much. With Yosemite and now Capitan it seems that everything just takes a bit longer now. My big itunes library takes longer to load, and anytime I have more than a few apps open it starts to slow. I have zero interest in buying one of the new MBP lite's that were released a few months ago so I'm mostly wanting to breathe a little life back into this one. About all that I have tried is Dr cleaner (I think that's what it's called) and I've noticed that when playing music and working on a doc and having a few web pages open the memory is basically maxed out. Any tips or apps that you've found that have actually genuinely helped. I've googled a bit but most of the reviews seems to be paid schills so I figured I'd come to the guys who use these every day.
