sorry if this has been discussed endlessly, but.....

 

I seem to have to be forever repairing permissions and recently re-installed the system fro 10.6 CD, then software update to 10.6.8 again.

 

I mostly only use a few programmes: DxO optics (photoprocessing), GraphicConverter (photo-sorting etc) Safari, Mail, Nikon Transfer (getting the images from the camera). I would use Nikon Capture more only daren't. They are all latest versions. Don't want to move to 10.7 as I also occasionally use progs needing Rosetta (Color-it & FocusMagic plug-in for CS4)

 

The progs seem to fight each other for memory/CPU attention, then slow down when they don't get it. Safari is at least as bad as the others, though its DxO that actually needs the power.

 

There is no obvious hardware fault.

 

Is there anything else I can do to try to improve things?

    4GB of RAM should be enough but more is always better.

     

    Obvious question: how much free space is left on your hard drive?

    What leads you to believe that you need to repair permissions?

     

    In Console.app, is there any frequently-recurring error message?

     

    How much free disk space have you?

     

    Post a screen shot of the System Memory tab in Activity Monitor.app.

    In Console.app, look at the console messages for repeating errors.

    Boot up from your Snow Leopard Install DVD while holding down the "c" key.

     

    Select the language you wish to use, and then choose "Disk Utility" from the menu bar.

     

    Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.

     

    If Disk First aid is unable to complete the repair you will need to use a stronger 3rd party utility like DiskWarrior or TechTool Pro.

     

    Once this process has been completed restart your computer.

    Your MBP running slow wireless or when using ethernet?  Both? 

     

    You may wish to reinstall the OS using the Mac OS X 10.6.8 Update Combo.

    That won't reinstall the OS.

    What does it do then?  I thought the combo installs more stuff than the regular update from Software Update.

    It will possibly fill in any corrupted or missing files from 10.6.0 on. It may sometimes be useful as a troubleshooting step, but it is not the same as a reinstall. A reinstall, which involves booting and installing from the install DVD, will revert the system files to whatever version as of the install DVD, while leaving settings, users and third party programs in place.

    So noted.  Thanks for the heads up!

    First, there will always be repeating Permssions messages. You can ignore those and stop repairing Permissions; it's not needed.

     

    Two ways of dealing with the slowdowns. I'm not seeing any excessive paging in your System Memory screenshot, but it might help anyway to run fewer programs concurrently, if possible. Other than that, install Developer/XCode from optional installs on the install DVD. When things slow down, you will be able to run purge (from Terminal), which will clear the virtual memory being used. But this will only be a temporary fix, until the VM starts accumulating again.
