I just got this mac over the summer. It's been amazing, however just within the past month it has been acting up with the web browser application - Safari. It seems to be slow loading certain webpages and almost always has a problem loading videos (Hulu, YouTube, etc.). I deleted the history, cookies, cache, etc. I have ensured that youtube.com/html5 is disabled, I have checked the preferences and even reset safari to no avail. I logged out of my account and into the guest account and safari works fine there, but not in my own account. I'm fine losing my bookmarks and saved information in Safari if I need to reset it, but how do I go about doing this. Any help is greatly appreciated. =/

MacBook Pro (13-inch, Mid 2012), Mac OS X (10.7.5)

    Safari Preferences Extensions


    from the Safari menu bar. If any extensions are installed, disable them and test.

    I don't have any extensions, but I still have the problem.

    Please read this whole message before doing anything.

    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

    The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.


    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
    • Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    • When you see the gray Apple logo, release the shift key.
    • If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.


    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    Test while in safe mode. Same problem?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
