Hello all


I am running macmini 2012 with a 2.3Ghz i5 processor and 8GB memory (OWC). The memories are loaded and reading properly in system profiler.

I have 10.8.2 (upgraded from native Lion)


I have noticed everything has a delay in response. When opening Mail, I click it and there is a 2-3 second lag before the icon bounces and responds.

Going from one message to another in mail, has another lag time that is annoying and sometimes up to 5 seconds long


Opening any application carries with it an unusual lag in response time.  I don't normally get a spinning beach ball


I have tested the RAM and HD with Drive Genius and they appear fine.  I have also defragmented the HD, although it shouldnt' really be a problem as over 90% of my space is free.


In Activity monitor, other than "kernel task" there aren't many apps that bog down the memory, other than "Safari Web Content" which only registers 0.9%-4% of CPU memory


The system memory has 0 page/out so there isn't much data swapping betweeb physical and virtual mems


Any ideas would be greatly appreciated

    Ok open System Preference go to start up disk check and to see if your start up disk is set in blue and restart

  • VikingOSX Level 5 Level 5 (4,710 points)

    Steps that I would take:


    1. Press Shift+command+U and start Disk Utility
      1. Select your boot drive in the left panel
      2. Choose First Aid
        1. Verify Permissions
        2. Repair Permissions
        3. Verify Drive
    2. Boot into Safe Mode
      1. Boot/Reboot and press/hold the shift key until grey progress bar appears
      2. At Login prompt
        1. Usename
        2. Password
        3. Press/hold shift key and click right arrow to login
        4. Release shift key when desktop menus appear
    3. Reboot normally


    You should see further improvements.


    For Mail:


    1. Select individual accounts under Inbox.
      1. From Mail > Mailboxes menu
        1. Choose Rebuild


    You have just rebuilt the Mail indexes for each account


    From what I gathered from your post, you actually have a 2011 Mac mini that you may have purchased in 2012. No late 2012 mini came with Lion.


    After you have done all of the above, launch Activity Monitor (shift+command+U) and have either All Processes, or All Process, Hierarchically chosen. Click the % CPU column if it isn't already showing the ▼ descending sort indicator. Anything other than the kernel hogging the CPU?


    On my machine, same as yours, my CPU % system rarely rises about 2% with Activity manager running and a Safari window open. Under System Memory, my Page Outs are 0.


    Apply or check the above and post back.

    Please read this whole message before doing anything.


    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.


    Step 1


    The purpose of this step is to determine whether the problem is localized to your user account.


    Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”


    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.


    Test while logged in as Guest. Same problem?


    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.


    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.


    Step 2


    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.


    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:


    • Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    • When you see the gray Apple logo, release the shift key.
    • If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.


    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.


    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.


    Test while in safe mode. Although it's slow, there should not be a distinct lag. Same problem?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    Synergy allows a user to share a mouse and keyboard with a windows computer through LAN....Could this be causing any of this??


    It could, but it wouldn't run in safe mode unless you started it manually. Did you?

    Please follow these directions to delete the Mail "sandbox" folder.

    Back up all data.

    Triple-click the line below to select it, then copy it to the Clipboard (command-C):


    Quit Mail.

    In the Finder, select

    Go Go to Folder

    from the menu bar. Paste into the box that opens (command-V), then press return. A Finder window should open with a folder named "" selected. If it does, move the selected foldernot just its contents — to the Desktop. Leave the Finder window open for now.

    Relaunch Mail and test. If the problem is resolved, you'll have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.

    Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
