Since few months, I've been noticing that it takes too long to start up my macbook pro


I sot by the Apple store and they told me to set it back to factory settings, but I'm not sure how to do this


Is there a way to find a step by step process to do the reset?

¨Thanks a lot


MacBook Pro, Mac OS X (10.7.2)

    I would try a SafeBoot-  this deletes the dynamic loader cache.  Then reboot-  the first reboot is noticable longer as the cache rebuilds.  See if this helps.


    Also in >SysPrefer>Users and groups  look at your log-in items in your account,  remove from the list anything that is launching on start up to slow you down.

    How slow is it, and at what point does it seem to lag: before or after you enter your password to log in?

    Very slow, before upgrading to 10.7 it took less than 1minute from switch on to enter the password an few more seconds to start working.


    Now it take 3 mins or more to get to password and maybe 1.5 mins after thevpassword

    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. Select the messages logged after the boot, during the time something abnormal was happening. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).


    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.


    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 this discussion.

    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.


    Step 2


    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of 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 — they're very long and not helpful.
