Safari 6 keeps lagging and it takes forever to upload most websites, it doesn't matter if it's this Comunity Support page or a website with flash, YouTube or otherwise. And if I try using YouTube (for example) once the website is finally uploaded and ready, I can expect to wait for the video to start for at least three times as long as the website upload. And the video then play for about 3 seconds and it needs to buffer, for about 10 seconds to play another 3 seconds. If I try opening up a newspaper website the article thumb pictures usualy never show at all.


I tried Reseting Safari, didn't help.


I emptied the Caches, didn't help.


I changed the DNS, didn't help.


I deleted certificates that were out of date, didn't help


Everything on the Mac (MacBook Pro) is updated.


I don't have any fancy Plug-Ins or Apps.


I have fast Internet.


There's nothing wrong with my Wifi as I've got other stuff hooked up to it that runs smoothly, including my Iphone and iPad.


I don't have too many things hooked up to my Internet Connection either as other people (visiting) use my Internet (with their Mac and computers) and theirs run smoothly as well.


Lastly I'd like to add that I haven't had any problems with my MacBook Pro, Mountain Lion or Safari 6 until this problem started. And I have restarted the Mac after every above mentioned attempt at solving the problem.

    What year MacBook Pro and how much memory is installed? Also, what version of Flash is currently installed?

    Delete the alternate DNS entry and reboot the machine, don't need any trouble from that.



    Run through this list of fixes in a systematic manner


    ..Step by Step to fix your Mac



    Creating a new user account and logging into it will determine if it's a user account issue of some sort.


    #12 OnyX cache cleaning will clean system caches that could be causing your issues.

    Why is my computer slow?



    Also why do you only have one web browser on your machine?


    Use Firefox as a extra or your primary web browser, it's the most feature rich, customizable and fastest browser, not based upon webkit which is known for it's security problems.


    Web browsing for hard of seeing users


    Maintain some level of privacy/cookie tracking

    This may sound a little harsh and it's not that I'm not wiling to work to solve this problem, in fact I've been googling and reading and trying a lot already. So this long "to do" list is just out of the question. These kind of lists are the exact reason I went from using PC and IE to using Mac and Safari.


    Mac's are computers just like Windows PC's are.


    Any perception that they run any better than a Windows machine is sorely mistaken one.


    You can hunt around forever trying different things and having to wind up erasing and installing everything or you can be methodical and fix things in a process of elimination manner.


    The fact is we can't see your machine and have no idea what you have done or what's been done to it or what other things you can't tell us is causing some of the issues your seeing.


    The Steps are designed to flag other issues and make sure everything is working as it should, narrow down your problem into smaller chucks so we can corner the problem and solve it.



    I may be persuaded to surrender Safari and try FireFox, but I don't see it as a good solution to keep both. One should suffice if Apples advertising is anything to go by, I was told by Apple salesmen that Mac was the choice for people who wanted stuff that works rather than stuff you had to re-build, extend and repair.


    You always need more than one browser on the machine for issues just like your having.


    I'm glad you took the time to answer my question, but I was hoping that the extra money I put in when I chose Mac was going to relieve me from these kind of deep set issues...




    There are now about the same amount of issues on Mac's and Windows 7 PC's now.


    Windows XP was a nightmare.



    Take your machine to a local PC/Mac software repair shop, any hardware repairs take it to Apple.

    Please answer as many of the following questions as you can.

    1. Have you restarted your router and broadband modem (if separate) since you first noticed the problem? If the answer is no, please do that now and see whether there's any change.

    2. Are any other web browsers installed, and are they also slow?

    3. What about other Internet applications, such as iTunes and the App Store?

    4. Are there any other devices on the same network that can browse the Web, and are they also slow?

    5. If you can test Safari on another network, is it slow there too?

  • Linc Davis Level 10 Level 10 (107,550 points)

    Do you want to fix the problem, or have you already decided what to do about it?

    I apollogize if I seem somewhat unwilling and ungreatful but it is VERY frustrating to pay three times as much money for a MacBook Pro and still have to deal with "Windows" type of problems.




    You are not experiencing "Windows type of problems" you are experiencing computer problems. Unless you follow the troubleshooting advice already provided you will not solve your issues.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.


    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.


    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.


    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.


    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.


    Launch the Terminal 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 Terminal in the icon grid.


    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.


    Step 1


    Triple-click the line of text below on this page to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2


    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read LoginHook; sudo crontab -l; } 2> /dev/null | open -f -a TextEdit
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.


    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.


    Step 3
    { launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; crontab -l 2> /dev/null; } | open -f -a TextEdit
    Step 4
    ls -1A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit
    Important: If you formerly synchronized with a MobileMe account, your email address may appear in the output of the above command. If so, anonymize it before posting.


    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.


    You can then quit Terminal.
