    Boot in Safe Mode


    Keep in mind, a Safe Mode takes much longer than a normal boot.


    Once you are in Safe Mode, right or control click the MacintoshHD icon on your Desktop then click Get Info.


    See:   Capacity & Available. Make sure there's at least 15% free disk. Any less could be why it's taking your Mac so long to startup.


    To restart, click the Apple menu icon top left in the screen. From the drop down menu click Restart.


    If there's enough free disk space, restart your Mac while holding down the Command + R keys for OS X Recovery OS X Recovery


    The startup disk may need repairing.

    If it is stalling at login when you enter your password, uncheck the apps that are loading at that time.  eg. Dropbox will take time to sync and anti-virus programs may need updating etc.

    It's not clear whether you can log in, except in safe mode. Can you?

    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. If you don't see that menu, select


    View > Show Log List


    from the menu bar.


    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.

    Do you, by any chance, have an empty SD card adapter connected to your Mac? It messes up after the 10.8.4 update.

    I'm having this problem and I followed those instruction and nothing really jumps out. Just a lot of kernels. I don't really know what to look for anyways.
