I know several others have had this problem, but was there ever found a solution ??


I never had the problem before, but now all of a sudden mtmd and mds processes consume huge amounts of CPU (+250% together) and I cannot really work on the laptop. It pretty much started after my external Apple 24" monitor froze and I had to hard boot.


I am running Parallels and made Bootcamp "private" because of other performance problems with mds.

I am also running backups to Time Machine, but have now been forced to turn this off.


When running Kaspersky AND Time Machine turned on - I cannot work at all.


So, was there ever found any solution to this (other than turning off Time Machine, which is probably not the intension from Apple).


I am running X Lion on a 15" Mac Book Pro from June 2010, 2,66GHz, Intel Core i7, 4 Gb DDR3. All software updated as far as I know. Also, just updated the firmware on the Time Capsule.

Mac Pro, Mac OS X (10.7.2), Parallels Desktop

    Please read this whole message before doing anything.


    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.


    The purpose of this exercise 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:


    • Be sure your Mac is shut down.
    • Press the power button.
    • Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    • Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).


    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 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.


    Test while in safe mode. Same problem(s)?


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

    Uninstall the Kaspersky crapware, reboot, and test.

    You can try deleting the Spotlight index and having OS X rebuild it. To do this, go to the Spotlight system preferences and add your hard drives to the "Privacy" list. Then remove them and wait for Spotlight to re-index the system.

    Both are useless garbage.

    An automatic transmission and ABS brakes are useless to a racecar driver, but for most people they're quite handy. AV utilities are not without their problems, but are progressively becoming more and more needed by the non-technical OS X users who need assurance, if nothing better, that they can catch malware if/when it happens.

    If you're going to use any AV software use the free ClamXAV, available here, which plays well with Mac:



    Kaspersky is well known to cause issues with Mac.

    MacKeeper has caused thousands of users untold damage more serious than any virus or malware than any I've heard of.
