    Since updating to Yosemite, my fan has been running slightly louder than normal.
    Also, there is a constant "loading" sound... the sound I expect when to hear when the computer is working hard to load something. It's similar to the high pitched, background drone of insects on a summer night. Certainly not loud, but annoying, as I've come to expect near quiet from this machine.

    When no apps are open, Activity Monitor shows nothing using more than about 1-4% of my CPU, but the loading noise and fan noise persist.

    While running Safari, everything is very slow and I see the spinning color wheel about every ten seconds. Activity Monitor says Safari is using anywhere from 30% to over 100% of my CPU?


    Any ideas? Thanks!

    It's time to go for SSD ;)

    Anyway, for a newly installed OSX, the initial spotlight indexing may takes a long time.

    And Safari still quite buggy in Yosemite, not much we can do about it.

    For the fan noise, did you check the fan speed? different OSX should not cause extra noise, unless the fan speed changed.

    Thanks for the reply. I actually updated to Yosemite three weeks ago, though, so it's had some time...

    Try a different browser.

    Boot from another disc or recovery partition and run repair disk and repair permissions.

    Have a look at Smart status.

    I have a 3,1 and it isn't laggy like that. An SSD is a MUST in Yosemite
