I recently added 2GB of memory after talking to Apple support as a way of speeding up my late 2006 20" iMac.  Unfortunately, that was NOT the solution.  So here's my problem:  I can do very little, from scrolling to even moving the mouse cursor without the rainbow wheel turning.......and turning, and turning.  In short, I am being held captive by a all-but-functionless computer.

I've run MacKeeper, TechTool device and MacScan all with the hopes of speeding my iMac up, but to no avail.  And there is still a good deal of space left on my Hard Drive.  Can anyone offer some possible solutions?  I'd like to conquer this problem before moving on to a new iMac.

    First you need to uninstall MacKeeper: How to Remove MacKeeper. Uninstall MacScan and TechTool. See the following:

     

    Things You Can Do To Keep Your Computer From Slowing Down

     

    If your computer seems to be running slower here are some things you can do:

     

    Boot into Safe Mode then repair your hard drive and permissions:

     

    Repair the Hard Drive and Permissions Pre-Lion

     

    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.

     

    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

     

    Repair the Hard Drive - Lion

     

    Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.

     

    Boot to the Recovery HD:

     

    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

     

    Restart your computer normally and see if this has helped any. Next do some maintenance:

     

    Suggestions for OS X Maintenance

     

    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.

     

    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.

     

    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.

     

    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.

     

    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.

     

    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.

     

    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):

     

      1. Carbon Copy Cloner

      2. Data Backup

      3. Deja Vu

      4. SuperDuper!

      5. SyncTwoFolders

      6. Synk Pro

      7. Synk Standard

      8. Tri-Backup

     

    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.

     

    Additional suggestions will be found in Mac maintenance Quick Assist.

     

    Referenced software can be found at CNet Downloads or MacUpdate.

     

    Additional Hints

     

    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.

     

    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.

     

    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.

     

    Check for applications that may be hogging the CPU:

     

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.

     

    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

    Thank you AND thank you again.  I'm going to approach this slowly and with intention.  And Kappy, this is more info than I've been able to glean anywhere else.  Again thank you and I will report back on my (hopefully) success.

    I've run ... MacScan all with the hopes of speeding my iMac up, but to no avail.

    A couple of comments concerning MacScan. It started out as a nitche utility to detect and dispose of "spyware" and tracking cookies, neither of which are considered malware by most A-V vendors. The reason being that most spyware apps are actually commercial utilities or hacks that require physical access to the computer in order to install.  Since this is usually done with the users knowledge and permission, it's not something standard A-V software has any need to deal with. In recent years MacScan has broadened their focus to include some, but not all other types of Mac malware. It does not provide the broader malware protection that most other A-V software does and it rarely updates it's signature database more than once a month.

     

    It is also known to produce "false positives" due to the way it attempts to identify it's targets, so be sure that anything it finds is actually something you don't want on your Mac before you decide to eliminate it.

     

    It won't slow down your computer, except when it's actively scanning and it may help with eliminating tracking cookies, but they will eventually come back if you don't use some other method of blocking their installation. Ghostery is a browser extension that helps me with that. There is no reason for you to remove it. There might be a time when you'll find it useful.

    I think thou doth protest too much.

     

    As one who could care less who gets the credit as long as it gets fixed, you are more than welcome to have my points in this matter. Not sure what that does for a level 10, but you've obviously gotten your fair share of the credit in the past, and rightly so. At least he verbally thanked you in advance of trying all you suggested.

     

    I would agree that you provided most of the other info, but none of what I posted and note that I don't support your advise to uninstall MacScan.

    Hi Kappy......I haven't delved into all of your instructions quite yet (I need to be totally in the frame of mind to do so, so that I can concentrate to the fullest), but rest assured, that with your body of knowledge and your history (I read your profile) of Mac work, yours are the plans of attack that I am going to follow.  From the get-go, I sensed that you know what your're talking about.

    THANK YOU KAPPY!!!!!

    Hi

     

    I had the identical problem with a friend's iMac - -same drive etc.

    Tried everything -- for no result -- re-installing Lion took 24 hours.

    BUT

    I found the answer.

    In the list of LOGIN items of my friend's computer was Techtool Pro Protection from the Tech Tool Pro Platinum that came withthe machine. The tipoff came when I removed Techtool Pro Platinum as it was not Intel code. I remembered having seen the TTP Login item.

    Remove it, Reboot and the machine is better than new.

     

    Hope this helps you

    As a TechTool Pro beta tester, I'm embaresed to say I've never heard of TTP Platinum.  I know there was a TechTool Deluxe that came with AppleCare for many years (I was not involved). I do recall when that they had a Universal Binary version (PPC and Intel) ready very shortly after the first Intel Macs hit the street which would have been early 2006, so that had to be a very old piece of software.

     

    I will agree that PPC only software has caused a bunch of problems for Lion and above in ways that defy explanation. It's not just applications that won't run, it's the internet plug-ins, frameworks, and other non-application executables that are often at fault.

     

    I always recommend users who migrate to Lion run this script to find an eliminate them. It takes a long time to run, so start it on your way to bed.

     

    This thread is a bit old, but perhaps it your suggestion will help users that bothers to search for answers.
