My computer has started running really slow.

It takes about 3 minutes for things to print.

Other applications are running slow - such as Photoshop - the spinning wheel is a common occurence. This suddenly happened about a month ago.

I have removed files in an effort to help, thinking it was becoming overloaded, but this is not helping.

I have run a virus scan - nothing.

Any suggestions?

    Do not continue to  randomly delete data that you do not know what is or why it needs to be deleted.

     

    Completely uninstall any virus software per the instructions on the developer's website.

    Antivirus software can slow down the normal operation of OS X and have other adverse! negative effects on performance and operation of OS X.

     

    Do do you have any garbageware hard drive "cleaning" style apps on your Mac. Completely uninstall these per the instructions on the  developer's website, also.

     

    How Much RAM installed?

    How full is your hard drive? If your hard drive has 15 GBs or less of free space, then it is time for some housecleaning of the hard drive.

    You may want to run these "standard" fixes if the problem persists.

     

    1) Check the amount of free space on your harddrive.  You should have a several gigs free.

     

    2) You should run disk utility

          Macintosh-HD -> Applications -> Utilities -> Disk Utility

          a) verify the disk

          b) update your permissions.

     

    3) Try a safe boot.

         Shutdown your machine.  Hold down the shift key.  Poweron.  Wait awhile; wait awhile while you harddrive

         is being checked.

    4) Another way to correct filesystem problems is into single use mode.

         This page will tell you how to get into single user mode.

         http://support.apple.com/kb/HT1492

     

        Basically, you hold down the command + s key then  powering on your machine. The command key

        has a little apple symbol on the lower left. It is between the alt/option key and the space bar. 

     

    4) You may want to run applejack to clean up your machine.

          http://applejack.sourceforge.net/

     

    6) Run hardware diagnostics.  It's good for a sanity check.

    Some semi-randomn thoughts on addressing performance problems.

     

    Activity Monitor
    Look at what is happening with your Mac when you run Activity Monitor.

     

    Macintosh-HD -> Applications -> Utilities -> Activity Monitor
    Click on the CPU tab on the lower half of the window. Make sure the little triangle is pointed down.  Make the triangle point down by clicking.
    With the down pointed triangle, you will see the apps which are using the most of the processor.

     

    You can gain some understanding of Activity Monitor by  looking at it every once in a while.  Look at the small graph.

     

    Here is how I have my cpu display set up:

    AppleJack
    "AppleJack is a user friendly troubleshooting assistant for Mac OS X. With AppleJack you can troubleshoot a computer even if you can't load the GUI, or don't have a startup CD handy. AppleJack runs in Single User Mode and is menu-based for ease of use."
    http://applejack.sourceforge.net/

     

    Console
    You can use the console application to examine Mac OS log files.  The logs will contain information on various system processes.

     


    Macintosh-HD -> Applications -> Utilities -> Console

     

    File > open console log
    this will display the startup messages

     

    and
    file > open system log
    once the system is started, messages will go into the system log

    I've discovered since I wrote about the scripts in 2010 that, starting with OS 10.5, the scripts are now coded to "catch up" if the computer is not running at the prescribed times. The only Macs I have where I still run the scripts manually are those running 10.4.

     

    The old march of technology!

    Thanks for all your replies.

     

    I am complete novice to all this side of using a Mac.. (i.e. don't know much!)

     

     

    Checked free space on hard drive -

    I ran disc utilility when back ups on time machine started failing. I ran it on the disc used for back ups and got the following report:

    Incoreect number of extended attributes - it should be 1224469 instead of 1224470. Incorrect number of access Control lists it should be 1224434 instead of 1224435. The volume 1123 needs to be repaired. Error Filesystem verify or repair failed.

    I did a disc repair and then all was well - apparently.

    Tried to back up - still not working. Got error message Time machine error - this backup is too large for the back up volume. (Is very little on there!) The back up requires 173.3 GB but only 132.6 GB avaialable.

     

    Disc utility on hard drive came back fine.

     

    I tried a safe boot - things like photoshop now running relly well - no wheel at the mpoment. However, now taking 10 minutes or so to send data to printer - not sure it is going to print at all now......I'm still waiting for it to print one sheet of A4 with word testing written on it.

     

    Not sure how to use Applejack - not sure about siingle use mode etc....

    You have enough free system memory -- over 50 percent.

     

    You have enough free hd space.  No need to delete files.

     

    Disc utility on hard drive came back fine.

     

    You ran disk utility on both the startup drive, the internal drive and the external backup drive?

    This is interesting.  seems like you have some extra programs running. We will have to figure out what they are.

    What printer do you have?

     

    Let's look at CPU usage.

    Macintosh-HD -> Applications -> Utilities -> Activity Monitor

    Look at my activity monitor image.

     

    allprocesses2.png

    Make sure you are looking at all processes.

     

    cpu2.png

     

    make sure that you have clicked on the cpu tab.  make sure the triangle is down.

    Skip this for now

    Looks like you have 412gig of data on your startup drive seems more than a little to me.  I do not have experience with time machine.
