Hello

My 2011 Imac takes 5-6 minutes to boot up. Once it boots up the computer seems to run fine. I have tried several things to try and fix the issue but have had no luck. Any advice would be great.

Thank you

Richard

    Install or Reinstall Lion/Mountain Lion from Scratch

     

    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

     

    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.

     

    Erase the hard drive:

     

      1. Select Disk Utility from the main menu and click on the Continue button.

     

      2. After DU loads select your startup volume (usually Macintosh HD) from the

          left side list. Click on the Erase tab in the DU main window.

     

      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on

            the Security button and set the Zero Data option to one-pass. Click on

          the Erase button and wait until the process has completed.

     

      4. Quit DU and return to the main menu.

     

    Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible

                because it is three times faster than wireless.

    Did you get a recall notice for the hard drive? Seagate 1TB drives are being replaced:

    Hi Richard,

     

    Hello, see how many of these you can answer...

     

    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...

     

    http://support.apple.com/kb/PH7029

     

     

    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?

     

    How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.

     

    Open Console in Utilities & see if there are any clues or repeating messages when this happens.

     

    In the Memory tab of Activity Monitor, are there a lot of Pageouts?

    If you have more than one user account, these instructions must be carried out as an administrator.

     

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Step 1

     

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.

     

    Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages loggedafter the boot, during the time something abnormal was happening.

     

    For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. Please include the BOOT_TIME message at the beginning of the log extract.

     

    Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into a message.

    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

     

    Step 2

     

    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs.

    I did get the recall notice and have had the hard drive changed.

  • 6. Re: Imac takes 5-6 minutes to boot up
    BYRichard Level 1 Level 1 (0 points)

    I have 1.46GB of free RAM and zero Pageouts, i have ordered more RAM but i'm not sure if its going to help with this problem. Also i ran a hardware test and everything seems to be fine.

    RAM is not the problem. If you refuse to reinstall as suggested, then:

     

    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.

    Kappy

    its not that i refuse to reinstall mountain lion, its that i'm not sure how to do it properly. When i bought my computer it shipped with snow leopard, since then i have upgraded to lion then mountain lion. will my install disks still work? or can i just reinstall from the app store by re downloading mountain lion?

    Thank you

  • 10. Re: Imac takes 5-6 minutes to boot up
    Kappy Level 10 Level 10 (226,775 points)

    If you follow my original post it outlines how you reinstall Mountain Lion without erasing your drive.

     

    Maybe "refuse" came across a little harsher than intended. Perhaps a better choice would be "can't."

     

    You have a number of alternatives to explore without have to erase your hard drive. However, it all else fails, then you may need to erase and reinstall. But for now you can avoid anything too extreme.

    Turn off the built-in firewall. If you're behind a router, it serves no purpose. See whether there's an improvement.

  • 12. Re: Imac takes 5-6 minutes to boot up
    BYRichard Level 1 Level 1 (0 points)

    Turning off firewall didn't help, still the same boot up time, apprx. 5 min 30 seconds.

  • 13. Re: Imac takes 5-6 minutes to boot up
    Linc Davis Level 10 Level 10 (117,995 points)

    Please post the first few minutes of log messages.

    Do you have any external drives attached? If so try booting without them, any periferals actually, and if it helps plug them back in one at a time.
