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.

iMac, Mac OS X (10.7.5)

    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.

    If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the boot drive, or some other hardware component, is failing. Back up all data immediately, then run the Apple Hardware Test or Apple Diagnostics.

    Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly.
