    After complaining that my 2008 Macbook pro was gonna die soon, my company gave me another hand-me-down. I have a 2.8Ghz Core 2 Duo. I immediately upgraded to 8GB ram, but it still seems very sluggish. It will often freeze for a moment when running basic applications, as well as not keep up when I'm typing at times. Anything I can do to help with this, or even w/ 8GB RAM, is this just as good at this computer will run on Mountain lion?

    I actually installed ML on a 2.0Ghz C2D/4GB alu uMB and it runs fine.

    Have you tried doing a full system restore? Because it shouldn’t be lagging - I have a 2.22Ghz MBP with only 4GB of RAM and it doesn’t lag (much).

    Consider putting an SSD in it, it's a pretty old MacBook though.

    Used ML on my 1.4ghz c2d MBA and it worked fine.

    When I had a Mid 2009 Core 2 Duo 2.66Ghz ML ran awlfully hot and it even turned off on me a couple of times which when it had Lion never did. It had issues. Battery life was cut down and the temps were awlful, wish I could say the samething about my current one but the battery life not that well. I feel like downgrading it to Lion.

    It's slow on my Early 2011 with 8 GB, with magnetic drive. ML seems to really be built for SSDs; my desktop has an SSD and it's nice and quick on there.

    Try restoring your mac. It should run fine after that. Mine's running quite alright on a 2009 c2d MBP.

    Also, consider replacing the HDD with an SSD. :cool:
