Safari 6.0 starts to hang after a few minutes of use

Hi all,


First thanks for the view. I love safari and do not want to use chrome but at times it is the only browser that functions properly. I can't seem to figure out why Safari performs great for 5-10 minutes of use then as soon as I try and load a different webpage, whether it is the same .com or not, it hangs for at least 1-4 minutes. Then, once it finally loads it is fine again and performs well, but it eventually happens again later. It is quite annoying. Any suggestions? I'm running ML 10.8.1 on a MBP retina display. Thanks for the help.

MacBook Pro (Retina, Mid 2012), OS X Mountain Lion

The next time you have the problem, note the exact times when it starts and ends: hour, minute, second.


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 page that opens.


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.


Scroll back in the log to the time you noted above. Post any messages timestamped during that interval – the text, please, not a screenshot.

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 A MESSAGE. If you do that, I will not respond.


Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

Some sort of norton error? What do I need to disable? Thanks for the help. Hope this wasn't too much code.

This comment applies to malicious software ("malware") that is installed unwittingly by the victim of an attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an attacker who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.


OS X versions 10.6.7 and later have built-in detection of known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.


The most effective defense against malware attacks is your own intelligence. All known malware on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of trojans, which can only work if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?


  1. Any website that prompts you to install a “codec,” “plug-in,” or “certificate” thatcomes from that same site, or an unknown site, merely in order to use the site, is untrustworthy.
  2. A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. [Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.]
  3. “Cracked” copies of commercial software downloaded from a bittorrent are likely to be infected.
  4. Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.


You should disable Java (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those versions has bugs that make it unsafe to use on the Internet. Those bugs will never be fixed, because those older operating systems are no longer being maintained by Apple. Upgrade to a newer version of OS X as soon as you can.


Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.


Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
