Over the past couple of months it's becoming harder and harder to get programs working in a fast and efficient manner. When I click on an email in the Mail client, it can sometimes take over a minute for it to move from one email to another. Although I realize Internet provider upload and download speeds play a part, during that same time it can take 4-5 minutes--leterally---for a page to be accessed and download. And I don't even want to talk about Aperture and it's plug-ins. This morning, it took well over 5 minuters for an Aperture plug in to be accessed and fully functional; and the past couple of weeks it can take 2-6 minutes for Aperture to download a photo already in the library and bring it up for working on.


I got a new iMac about 6 months ago and it started out working great, but thse past couple of months it's been one of the slowest and frustrating machines I've ever owned. I purchased MacKeeper in hopes that it would end the problems, and it has helped some, but not nearly enough For the past 7-8 years I have been a 100% percent faithful Apple Fanboy, but these issues are starting to make me want to throw my iMac, less than 7 months old out the window. It's got 4 GB Ram, but since it worked fine for the first few months, I'm thinking it's something else.


Any suggestions?

    Well, for one thing, 4 GB is an absolute minimum - running Aperture efficiently, you should really have double that. You might want to check Activity Monitor (Applications > Utilities) and check how much memory apps are using - post a screenshot of the high usage "offenders". Also, check at the bottom of the window under memory - can you post a screenshot of that part please.


    And, how much empty hard drive space do you have/maintain?

    My guess would be that you've got a bunch of crap third-party software installed. That is mostly based on the fact that you have one of the most reviled apps in Mac history installed: MacKeeper. It is well-known for bringing a healthy Mac to its knees and even damaging systems to the point that they need reinstalling. Get rid of it, and then go through all your other third-party software with a fine-toothed comb. You'll find some suggestions as to how to do this, as well as some other tips, in my Mac Performance Guide:

    MacKeeper will do that.

    Okay, if you like MacKeeper, it's your decision. I would not let it within 20 ft of any of my Macs.


    As for the RAM, your screenshot does not show. You need to use the little camera icon in the toolbar to post the picture.


    And, as for Aperture, most posts I've read report needing more RAM for it, but - again - if it works for you, great. I'd still like to see the screenshot of your memory usage.

    Make absolutely certain all vestiges of MacKeeper are really gone.


    You should also boot OS X Recovery and use Disk Utility to verify and repair your disk if necessary. Disk corruption or pending failure could explain this.


    To help identify other third party software that may be to blame, also consider the following. It may reveal something useful, or nothing at all, but is easy enough to do.



    Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:



    Don't be concerned about anything that says "Problem" or "failed".


    Copy and paste its output in a reply.


    Etrecheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.


    When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.

    Images are still unreliable on ASC babowa. I see it here:
