- Your Mac's Specs
- White Macbook (refurb), 1.83 GHz Intel Core Duo, 2 GB Memory, 60GB HDD
My 24inch 2.4GHz iMac is installed with Leopard and is pretty much an exact mirror of my Macbook, in terms of the programs installed and settings.
But whilst the Macbook runs completely smoothly, my iMac is very laggy at non-replicable random moments. For example, sometimes I would just be closing a window and it will take 1 or 2 seconds to close it, displaying a beach ball during the lag. Closing another window a moment later will probably be fine. This 1 to 2 second lag with the beach ball happens very often with the smallest tasks; stuff like browsing front row, expose, spaces, opening a new tab in safari. Its a miserable experience especially since my iMac is much more powerful than my Macbook!
I've got 4GB of Ram too and it happens regardless of how much free ram I have. I've tried to see if there is a spike in any CPU processes when the lag occurs, but there isn't anything unusual. I've looked at the Disk Activity but can't find a pattern between that and the lag.
I've had this problem ever since I've got my iMac, which is less than a year old. I recently reinstalled leopard to see if it'd make a difference, obviously not. I've run the Techtools Deluxe test which it passed. I haven't run Disk utility yet myself but that's because AppleCare recently changed the graphics card and told me that they ran Disk Utility themselves and found no error. Note: I thought the graphics card was the problem which is why it was replaced but the new one hasn't made a difference - the lag is still there.
Finally, I do notice that when I wake up from sleep my airport takes ages to connect to my wireless network (around 10 seconds) compared to my macbook which normally connects instantly (I did this test placing the iMac and Macbook in the same place).
I thought I could work this out myself with the aid of google but now I accept that I desperately need help!
