    iMac - Very Slow At Times
    I have an iMac running on version 10.9.2. The processor is an Intel Core I4 (2.7 GHz) and 4 GB of RAM. At times the operating system is very slow to the point where I can't do anything. I can hear the computer spinning quite a bit when this happens. The problem is much less after I reboot. Does this IMac need to restarted regularly. If so how I often? I typically rarely restart it. I have an older macbook air with less RAM and a slower processor that never has issues with speed and freezing up. Any other suggestions to optimize performance of the IMac would be greatly appreciated as well.

    How full is your hard drive and when was the last time you performed maintenance clean up on it? We only recommend one tool to perform maintenance cleanup: OnyX which is free. The link is for the version that works with Mavericks. Run OnyX in automatic mode and be sure to read the instructions first. Let us know if that helps speed things up for you.

    My hard drive has 850 GB of 1000 GB free. Should I use disk utility to run verify disk. I wasn't sure; especially since my mac did not come with a reboot disk.

    The trouble with downloading OnyX is that it wants to make Yahoo my home page, along with other alterations. The only way I can get rid of that condition appears to be by doing a custom install, and I am not competent to do that.

    Where are you downloading it? I've NEVER had Onyx try to change anything. Custom install? It's a drag-n-drop to the Applications folder.
    Always listen to experts. They’ll tell you what can’t be done and why. Then do it!

    The link "chscag" provided works just fine (you should click on the "direct link download" area). But if you prefer...use this link:

    Removed the Cnet link and inserted Titanium's above - Cnet is now auto installing what most of us would consider malware in the form of changing your home page, search engine and installing multiple adware extensions in Safari, Firefox and Chrome unless you catch it.

    Guess we now have another download site to stay away from - or at least make sure you read all the fine print.

    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    Thanks everyone. I have now downloaded from the Titanium site. I arrived at the original site by clcking the link. Curiously, I did not have the same result the second time, but reached Titanium.

    I note that in doing its checks the program has found that I do not have SMART. Should I?

    Are you saying SMART says Failed? If so that means BACK UP your data and NOW because the hard drive is about to fail.

    How long have you owned the iMac? Does it still have Apple Care?

    I hope I am not creating a stir over something I have misunderstood. If so, apologies.
    The message I get when I invoke the OnyX program to check on SMART is:
    "The SMART status was not verified because it is not supported by this hard disk"
    This suggested to me that SMART was not present.

    That is the message on the Internal drive that is built into the iMac? That is normally a message you would get from an external hard drive.

    I assume that is so. I have an external back-up drive. Is there a way of discovering which drive the OnyX program is looking at? I take it that my Mac would have SMART program?

    I saw this thread. Also want to try to clean the Mac. A Mac Book Pro 2010 running Mavericks. I went to titanium and downloaded the version for Maveriks. It said to drag the icon into either apps folder or the utility folder IN apps. I put it in the utility folder. When I click on it, I get a box that says it cannot be opened because it is from an unknown developer.

    That's a "Gate Keeper" warning which is a security feature built into OS X. Since we know OnyX is good application, right click on it and select open. It will then go ahead and install as per normal.
