    How I solved my slow iMac with constantly working HDD 


    The mighty iMac – great once you fix Spotlight

    A couple of days ago, I blogged about that I could have managed to solve a really frustrating problem that made my iMac dead slow. Turns out that I had.

    In short, my 27″ iMac has been really (really!) slow since I bought it. The HDD was working more or less constantly, especially when starting and waking up the iMac, but also when just running e.g. Firefox. When the HDD was reading and writing like hell, the iMac went into slow motion mode. I use OS X 10.6.7 and have a BootCamp partition on which I have Windows 7 installed.

    Neither the retailer, nor the service provider (to which i sent the computer for service) nor Apple Support were able to figure out why this was…and as a matter of fact, the SP did not even confirm the slow behavior. They probably just ran Disk Utility…and managed to scratch the chassi when doing so.

    Last Thursday, however, I finally managed to solve the problem and end 6 months daily frustration. To help others out, I sent the solution to my colleagues…and instantly received a bunch of responses from equally frustrated colleagues who had the same problem without being able to solve it.

    The problem turned out to be (as discussed at https://discussions.apple.com/message/12913591?messageID=12913591) that Spotlight tries to index the BootCamp partition. When it fails to do so…it just tries once more…then once more…then…well, you understand 🙂

    The solution is to add the BootCamp partition to the Spotlight ignore list. When I did, the problems stopped immediately and my Mac is now fast as lightning. It’s an amazing difference. You may need to re-add the ignore after rebooting (I had to do it once) and maybe add a certain file to the BootCamp root, but when you have, you will be in a world of speed.

    Now, since no one (except the great people at the forum) was able to help me out with this problem, my advice to Apple is to:

    1. Fix the Spotlight bug (duh)
    2. Recognise it, so that you know what is causing something that makes your great computers sooo slow and your customers soooooooo frustrating.
    3. Recognise it, so that, when people call in in desperation, you will be able to help.
    4. Please, tell your SP:s not to scratch my monitor the next time I send it to them. It is impossible for me to prove that they did.
    If you have the same problem, I really hope that you found a solution (and some piece of mind) here.

        Yeah, I’d like a PC with a really small screen instead.

      Thanks for the fix, it stopped after i deleted my bootcamp partition but it is good to finally know what it was. At the time i didn’t connected it to the spotlight. Thumbs up! 🙂

      Stinky, you’re name fits you like a glove. And it’s not about Mac vs PC, it’s more about Mac OS vs Windows and in that matter Windows is pretty crappy. You can have the best hardware out there and still be stuck to an unreliable operating system which tries to copy mac os unsuccessfully.

        Great to hear that it works well, Andrei! I am actually considering removing my Bootcap partition as well, and see if I can get my iMac to stop sounding like a percolator 🙂 It worked for a while, but now it is reading mostly all the time (but not as bad as before the fix).

      Daniel, this is an awesome advice. Thanks for sharing it. Though the post is a bit old, it still holds pretty well today 🙂 Two months ago, I updated my iMac to OS X El Capitan and it was extremely slow as well. It turns out it’s the same culprit – Spotlight indexing. Fortunately, after a day, the speed went back normal.

      I too, expect Apple would fix the issue. Hopefully in one of the upcoming updates. By the way, I also have a small blog dedicated to fixing slow iMac issues, in case other readers who read your article might be interested to know, it’s here: https://www.imacslow.com/

      I welcome you to check it out and would love to know any feedback you may have on the content. Thanks again!

        Insane that the problem is still around! My disk eventually crashed as well, and with the new SSD, the iMac is completely silent and (still, after all these years) lightning fast! 🙂

    Slow iMac about to be fixed? 

    I have been having a world of pain with my iMac 27″ (4GB RAM), on which I run Windows 7 on a Boot Camp Partition (using VMWare Fusion). It’s basically the same setup as I have on my MBP (which has 8GB RAM though), with the minor difference that the MBP is fast as lightning and the iMac is slow as HELL!

    Now, don’t get me wrong. I do not expect the iMac to be lightning fast when running both OS X and Win 7 with 2GB each, but you have to experience my iMac to know what I’m talking about. Basically, the HDD reads and writes a lot…all the time. Sometimes, it starts hammering the disc like crazy, during which the computer goes into slowmo.

    And…it does not matter whether or not VMWare is running – it’s dead slow anyway. Despite all my communication with various Mac Stores and Apple Support, no one has been able to help me…

    …until tonight, thanks to the people at https://discussions.apple.com/message/12913591?messageID=12913591

    The key concept here is that Boot Camp + Spotlight can go no no, causing Spotlight to constantly indexing the Boot Camp partition. I am almost certain (99% give or take) that this is what has been causing the slowmotion behavior for me as well.

    When I rebooted my computer, the disc was going crazy from start, as usual. As soon as I added the Boot Camp partition to the no-indexing list in Spotlight, the disk went quiet and the computer has been working SOOOO good since then. The Boot Camp exclude gets reset when I restart my computer, but I will follow the root folder file advice in the discussion and see if it helps.

    So, if anyone of the brave forum members at https://discussions.apple.com/message/12913591?messageID=12913591 reads this – thank you sooo much! You may just have ended six months of daily frustration 🙂
