Imac starting very slow

Since a few day my iMac is starting very slowly (at least 5 to 10 min). I don't know if I have done something wrong or my childrens...
Soft is up to date. I've got a HDD external for Time Machine but I have the same trouble with or without.
Only one internal HDD.
The model is 20 inch from early 2008, running under OS X Lion 10.7.5 (11G63).
Thaks for your help.

Hi..
Not enough free space on the disk can slow the system down.
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
Try removing login items. Open System Preferences > Users & Groups then select the Login Items tab. Remove all items.
And go to HD > Library > StartupItems. Remove all items from the StrartupItems folder.
Check the startup disk.
Launch Disk Utility located in HD > Applications > Utilities
Select the startup disk on the left then select the First Aid tab.
Click:  Verify Disk  (not Verify Disk Permissions)
If the disk needs repairing, restart your Mac while holding down the Command + R keys. From there you can access the built in utilities in OS X Recovery to repair the startup disk.
Be aware, OS X Recovery requires a high speed broadband connection.
And backup all your important files before repairing or restoring OS X just in case.

    Check your system Login/startup items in OS X System Preferences under the Accounts icon- Login items tab.
    If you have more than 6 items trying to launch at startup, you need want to remove these apps from the automatic launch/startup list

    Select your user account, then click Login Items.
    Do one of the following:
    Click Add below the list on the right, select an app, document, folder, or disk, then click Add.

  • Pulseaudio starting very slow

    For some reason, pulseaudio is starting very slow on my system, even when it was a fresh install.
    I was seeing very bad startup performance with several programs: firefox, hotot, etc.  I did an strace on them and found they were stuck on waiting for a PID associated with pulse for about a half minute.  When I turned off autospawn in the pulse config file, these programs loaded instantly, even if I put
    pulseaudio --start
    in my i3 config.
    I'm not familiar enough to know how to debug this.  Does anyone have any ideas of what I could do to get more information?
    My sound devices are the integrated audio from my motherboard (Intel), my Nvidia graphics card, and my webcam (HD Dualpix).

  • My macbook starting very slow i want to factory reset

    my macbook starting very slow i want to factory reset

    Hello sallay Amir,
    Thanks for participating in the Apple Support Communities.
    It sounds like you would like to erase your MacBook Pro and install a new copy of OS X, but the Mac does not boot to OS X Recovery when you hold the Command + R keys during startup.
    If your Mac came with OS X Snow Leopard (10.6) or earlier, I recommend referring to the steps in this article:
    Mac OS X v10.6 Snow Leopard: How to Erase and Install - Apple Support
    For a newer Mac (OS X Lion, Mountain Lion, Mavericks or Yosemite), try reinstalling OS X by using Internet Recovery, as described in the "OS X Internet Recovery" section on this page:
    OS X: About OS X Recovery - Apple Support
    All the best,
    Jeremy

  • My iMac started running slow now won't start at all

    Two days ago, my Mid 2011 iMac 27-inch, OSX Lion 10.7.5 started running very slow.  Had trouble opening and closing apps.  Then after restarting, it took an extraordinary amount of time to start.  Had to shut down by holding in Power button.  Restart failed a few times, then I was finally able to get to desktop but unable to open any apps.  After many tries and waiting about 30 minutes between each keystroke for something to happen, I got to Disk Utility.
    Under the First Aid tab, I ran Verify disk and got "The volume Macintosh HD appears to be Ok."  Repair Disk was not an active button.  At one point I got to the Force Quit menu under the Apple and force quitted Safari, iPhoto, and one other app (maybe Disk Utility) but then still was not able to Shut Down the computer.
    Some background info that may or not be important,  I have been unable to Empty Trash or Secure Empty Trash for a long time.  Most of my hard drive filled capacity (60%) are photos and videos.  After running for what seems a very long time, I'd get an error message about not having the right permissions to delete some files in Trash. 
    Back to Disk Utility, I tried to run Repair Permissions and Verify Disk Permissions, and both just ran forever (hours) until I stopped them.  After 6 hours of reading possible solutions in this community but being able to perform none of them, I unplugged the computer because I couldn't get to Shut Down.
    This morning, I plugged it back in and upon hitting Power, it took about 10 minutes to get the User icons.  I clicked on mine and got a gray screen with the spinning circle.  That was about 30 minutes ago and nothing has changed. 
    I welcome to all offers of help.  My concern is that I was in the middle of copying folders upon folders of photos and videos to an external hard drive for the past several weeks and still have not completed that project.  I look forward to a solution that would not result in the loss of photos an videos.

    When I selected Disk Utility, the Repair Disk button was active.  It ran for a few minutes then read, "The Volume Macintosh HD appears to be Ok."  Followed by "Volume repair complete" and "Updating boot support partitions for the volume as required."  I have no idea what that last statement means. 
    I just ran "Verify Disk" and  "The Volume Macintosh HD appears to be Ok" was the result.
    I also ran "Verify Disk Permissions" which wouldn't run yesterday but did just now.  Ended with "Permissions verifications complete."
    I ran Repair Disk Permissions, "Permissions Repair Complete."
    What should be my next step?

  • IMac is very slow after switching to OSX Mavericks

    I'm still getting used to the philosophy of this site, so excuse me if I stray.  I had posted in a different thread and was asked to start a new thread.
    I have a 20-inch, Early 2008 iMac and I've been upgraded to 10.9.4 for a few weeks.  I did have the fan problem, but sorted that out, forget what I did but may be able to retrace my steps.
    But, the machine is so slow now - really not tolerable.  Every program I launch just takes a lot of time.  Even launching Textedit that used to just flash up is sow.  Safari is now very slow to launch.  Google, which I use all the time and was normally slow, is now excruciating.  Logging on, I have to wait a long time to even put in the PW.  Once open, most applications are tolerable.  But, like others have mentioned, the machine is just slower at everything.  I watch "Activity Monitor" to see what's using what for memory and CPU, and nothing new with that compared to 10.6.8 except it's not as good giving me the information I want in an quickly readable form.
    Do I need to just go back to 10.6.8, or is this Mac's hardware is not compatible with 10.9.4?  It seemed that the upgrade was recommended for this machine.
    I'd appreciate any thoughts, recommendation, suggestions. Thanks!
    PS:  I was asked to send top 5 CPU and then the average User CPU....
    Firefox                    6.7%
    Activity Monitor     1.0 %
    Window Server     0.8%
    Firefox Plugin         1.1%
    kernel_task          0.4%
    User:                    4 - 11%
    As you know, these constantly change, but I just jotted things down in the list above.  Nothing was taking any serious time.  Firefox will momentarily go up to 30%.  I know when Time Machine is slowing things down because I can see it backing up with the icon on the menu bar, but that's not only when it's slow.  It's just always slow starting applications or opening new windows in Firefox, opening a new window in Word or Excel.  I always have Activity Monitor open to watch for anything unusual, like if Firefox is bogging me down.
    The question is should I expect this OS to be bogging this machine down, in general?  Thanks!

    It would be nice to know how much RAM is installed. A report of this would help:
    You should use Activity Monitor to check for:
    Open Activity Monitor in the Utilities folder.  Select All Processes from the View menu.  Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) 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.
    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities 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.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    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 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.
         Reinstall the 10.9.4 update: OS X Mavericks 10.9.4 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
         Reinstall the 10.9.4 update: OS X Mavericks 10.9.4 Update (Combo).
    Download and install EtreCheck 1.9.12. Run on your system and copy and post results here.

  • Brand new iMac running very slow!

    I just purchased brand new iMac on January 2nd (the specifications are below).  The computer seems to be running very slow just doing normal everyday tasks. I have barely even used the computer and the only installations I've done where the ones recommended from the app store.  I saw I had an itunes update the other day and went to install, the computer sat there for 5 minutes before it did anything.  After it installed the app store still had the badge icon #1 next to it as if it never installed.  During the installation I was listening to pandora, I tried to turn down the music and it took about 45 seconds before it turned down.  I finally tried to log out of my account and it took over 2 minutes to log out.
    I haven't had the opportunity to mess with anymore since yesterday.  I feel a brand new computer like this shouldn't be running this slow.  Does anyone have any suggestions?  I will probably be contacting Apple Support after I get off work and maybe even exchanging the computer for a new one.
    21.5-inch: 2.7GHz
    Specifications
    2.7GHz quad-core Intel Core i5
    Turbo Boost up to 3.2GHz
    8GB (two 4GB) memory
    1TB hard drive1
    Intel Iris Pro Graphics

    If you are referring to this icon for the App Store:
    the red numeral 1 is to tell you there is an update available. It may even have started to download, and been paused.
    As far as your Mac's performance goes the Apple Store is the place to take it. You have paid for a one year warranty, and of course there is the option to return it within 15 days. Good luck.

  • Imac  is very slow with downloading mail

    My imac is the ast weeks very slow with downlaoading mail.
    I am using mail 5.3 from apple
    Nothing has recently been chanched in my internet setting or internet speed
    Anybody an idea what can be wrong?

    Hi, I worked out what you recommended, but I do not see any difference at speed.
    Mail starts normal, though that is also somewhat slow,
    Before it has finished downloading mail (even is there os no mail!) it takes sometimes 2 minutes!
    Also there was no"boing"when starting up, with following your procedure, is it normal?
