Why is Safari running so slow under Mountain Lion?

Why is Safari running so slow under Mountain Lion?

I have other mac's on my home network that are still running Snow Leopard and the are performing well. I wanted to use the iCloud so I upgraded and instantly started experiencing the slow down, to the point of ridiculousness. Other function are mixed some normal speed, others a day on the beach with the spinning ball. Firefox is at full speed, good thought, haven't checked Chrome yet.
Last night and hooked into a projection unit that adjusted my screen resolution for a presentation and after the event my Mac reset back to the normal settings and Safari launched and is running normal speeds so far. In the past there have been issues with performance speeds and certain resolutions, has anyone had similar luck or is this a fluke?

    Since downloading Mountain Lion, why is Safari running very slow?

    You're going to have to be more specific and include some details.

  • Safari slow under Mountain Lion

    A friendly enquiry to the Apple Expert Community
    After I have upgraded my LION configuraiton with the latest MOUNTAIN LION Release, Safari has become very slow in loading web pages. I am connected to a highly performing Internet DSL Link (VDSL 20kbit's DL / 2kBit's UL).
    Under LION I had no problems in this area. Also I must mention; when using FIrfox under Mountain Lion (ML), the Internet and Web Page Loading Process is very fast!
    What have I done for test purposes:
    1) I deactivated all iCould services to see whether it would improve - no change - still slow
    2) I Did a clean ML Installation with no software etc on it - from scratch - all patches loaded etc. - Safari STILL SLUGGISH !
    Assumption:
    There is a bug or new feature within ML, possibly the new combined URL and Search Bar feature (searching ahead, etc) which slows down the load of Web Pages... ?
    Anyhow,
    The results of my short tests give me a strong indication (proof) of, the slowness of Safari 6 under ML is not caused by mal user handling or buggy software installed, but an initial insufficiency of the first release of ML
    Question:
    Does anybody have already found a slution to the described problem?
    many thanks for some feedback

    Launch the Keychain Access 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 Keychain Access in the page that opens.
    Click the column headed Kind in the list of keychain items to arrange the list by kind. Look for certificates that are expired or invalid. Delete any you find.

  • Stage/Timeline extremely slow under Mountain Lion

    Hello everyone,
    I'm having this issue with Flash CS6 on OSX Mountain Lion. Almost every action in the program causes it to slow down considerably. Things such as selecting/moving anything something on the stage, selecting something in the liberary panel, clicking buttons on any editor panel, and scrubbing the timeline. Even using the Mac's menu bar in Flash is slow. The slowest thing is playback from the timeline editor, it becomes so slow that it often crashes the application:
    Even though all of this is happening, every other application is running perfectly fine. Flash isn't taking more RAM or CPU that it usually does (except when it's about to crash), and I've only had this problem after upgrading to Mountian Lion, in Lion everything was fine. SWF file publish and playback have no problems whatsoever. The exact same problems are even effecting Flash CS5.5. I am an Adobe Creative Cloud member and all the other apps that I've tried work perfectly. I've also tried Flash CS6 in Windows on the same machine and that works as it should. This problem also consists on not only my existing .fla projects, but also brand new ones with absolutly nothing in the liberary or stage.
    I have an Early 2011 13-inch Macbook Pro with a 2.5 GHz i5 and 8 GB RAM upgrade. I also have the 32-bit version of Flash CS6 and CS5.5, and of course OS 10.8
    I have a Bootcamp of Windows, so I can keep working, but rebooting is a big hit on my workflow, so I plan to use my backup of Lion. But before that, I want to try and solve this problem.
    Thanks to those who read this! I hope I can solve this problem.

    Yep - I know the MacFuse is dead, but aparently it is the only way to run the free NTFS-3G plugin. All other options are commercial. I am trying now Paragon NTFS For Mac - if it works, I will have to buy it. And it's the same 20$ as I pay for the whole OS! So basically I will just consider going back to Snow Leopard - I know that I will have much less compatibility problems there in general... I will be able to also run Extensions Manager 1.8 (CS3) there, cause it also doesn't work on Mountain Lion (it is a known issue). It's just too much isn't working for me on 10.8 and Adobe

  • HT4848 Two days ago I upgraded my MAC PRO from Lion to Mountain Lion via my account at the Apple App store.  My machine runs so slow with Mountain Lion especially mail that it is completely useless.  It take about ten minutes per mouse click to register. 

    I also run Parralles 7.  I re-installed this a few times with no affect.  I have it not running and my Mountain Lion is still too slow to use.  Again a single mouse or keystroke takes up to ten minues to register. 
    Suggestions ?

    Then you can update or uninstall your problematic third-party software.

  • How to run PowerPC application under Mountain Lion?

    I ahve just upgraded my ancient laptop running Leopard to a newer model running Mountain Lion.
    I use a legacy application (Filemaker v5.5) for work that cannot be upgraded in the near future for my work.
    This is a PowerPC application that is  no longer supported. Is there an emulator or utility that will allow me to run this (and other) PowerPC applications?
    Is there a version of Rosetta or something similar I can get?
    The alternative is to create a Windows partition (shudder) and run it there.

    No Mac will run an OS or OS point version earlier than what it originally shipped with. You can see which iMacs shipped with Snow, from this link. That said, it's not entirely clear that even the mid-2011, if it shipped with Lion, will still be able to run Snow.

    baltwo said he got it running on a mid-2011 refurb, but on a separate partition from a clone.

  • Why does office 2011 run slow under mountain lion?

    I was in an Apple Store and launched MS Office (Word or Powerpoint) on a new iMac they had on display.  It was very slow.  I rebooted and repeated the event from cold.  It made no difference.  Is there a problem with M.Lion and Office 2011?

    I suspect it isn't that the program is running slow it's just these programs aren't made by apple therefore could take up alot of RAM space so the more apps you have open the slower your system will be. Try downloading apple's iWork (pages, keynote and numbers) and quitting some apps. You should see a major difference. If you would like to stick with MS Office just quit your apps. I doubt it's the program.

  • Why is safari running so slow

    Everytime I open safari all the sites even apple takes forever to load and is not internet connection I even went out and bought a new modem thinking it was the modem but is still running slow, wifi or ethernet.

    Since this is the forum dealing with the MacBook Pro Hardware, your question will be best answered in the Safari forum.  There are several steps that need to be taken, but you need to determine if Safari is the culprit or your network. 

  • Whys is my mac so slow with mountain lion

    Hi
    I have an early 2008 Macbook Pro with 4GB RAM. I recently installed ML and CS6 and I have had nothing but problems since. I have reverted back to CS5 Photoshop and illustrator which has improved things slightly but generally, my machine has become a nightmare. It's SO slow - and it's not just the system - my internet is also unbearable. I am a freelancer and connect to other networks onsite and I have exactly the same problems there too. When I have PS and ID running, Activity monitor tells me I am using 3.67GB RAM - and I only have 2 smalll files open. It has become virtually unworkable and it's just not good for the soul - I really need help!
    Any suggestions or tips would be very gratefully received.
    Thanks!

    First, back up all data immediately, as your boot drive might be failing.
    Take these steps when you notice the problem.
    Step 1
    Launch the Activity Monitor 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 Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    You must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way as above. 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.
    Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into a message.
    Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

  • HP Laserjet 100 color scans VERY slow under Mountain Lion

    i have uninstalled the software and drivers and reinstalled using the 10.8 installer form HP.  The scan process takes up to 2 minutes per page when under Lion a page could scan in 22-36 seconds.
    Anyone else have this problem or a solution for speeding the process up?

    I have this problem with hp 1536dnf. Have you found a solution yet?
    I'm having a discussion with an hp "Expert" on the hp site. You might want to join in with any solutions you've found or, if you haven't, to let them know the problem goes beyond the 1536dnf.

  • Why is my macbook pro running slow with mountain lion?

    After installing Mountain Lion, I find navigating, opening programs, etc. is taking more time, why is this?

    Immediately after installing Mountain Lion, your system will be rebuilding the Spotlight index. This should only take a couple of hours at most. If the problem persists you can run diagnostics. I just happen to have written a little diagnostic program recently. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.
    Disclaimer: Although EtreCheck is free, there are other links on my site that could give me some form of compensation, financial or otherwise.

  • Firewire, Virtual software and Chrome don't work under Mountain Lion.  Why?

    I upgraded two machines to Mountain Lion:  A Core i7 iMac and a Core2Duo Mac Mini running OS X Server.
    The first thing I noticed was that any virtual machine software icons - Fusion, Parallels and Virtual Box - show up with the circle crossed out, even though each version was the latest installed (came as part of a couple of MacUpdate bundles). 
    Then I noticed on the iMac, all firewire devices were not being seen.  I have a Lacie 4big Quadra hooked up via firewire 800, an LG DVD+R drive on firewire 400 (800 to 400 cable coming out of the Lacie) and an EyeTV 200, which all were working just fine under Lion.  System Profiler shows a "Maximum Speed:  up to 800 Mb/sec", but no devices listed as available.  I did dupe the original Lion installation to an external USB disk but haven't resorted to that yet.  Tried identifying all connected devices at the command line, but haven't had success finding the firewire devices.
    Finally, although the latest Safari is nice and fast, I have been accustomed to working with Google Chrome.  On the iMac, every time I attempt to run Chrome, it comes up crashing and asking if I wanted to report it, which I do.  I even went as far as to delete and reinstall Chrome and I get the same result.  What's up with that?
    Ideas?
    Regards,
        Tony.

    Since posting, I found out there were some updates available from VMWare, Parallels and Oracle (VirtualBox) which now allow them to run properly under Mountain Lion.
    I still have the problem with Firewire and Chrome though...  For Chrome, I have deleted and reinstalled but get the same result.  As for Firewire, I'm almost ready to "reorganize" my wiring from adding another powered hub and hooking some of the devices via USB, or just follow the lines and plugging and unplugging, although moments before the reboot from Lion to Mountain Lion, all firewire devices worked in the configuration described and nothing had since changed...
    Regards,
        Tony.

  • Did macbook air mid 2009 running slow with mountain lion?

    did macbook air mid 2009 running slow with mountain lion?

    Yours is the first computer I've heard about on these forums that is attempting to run Mavericks with only 2GB of RAM.
    Indeed that is acceptable per the Mavericks requirements:
    http://support.apple.com/kb/HT5842
    ... but as you may know, Apple has not sold computers with as little as 2GB RAM for quite a while.
    I suggest therefore you make sure you remove any applications that may be overtaxing your machine.  Examples are browsers other than Safari, Mac cleaning products (such as Mac Keeper), or any other non-Apple app that has some startup process running (such as Outlook).

  • MacBook Pro runs slow after Mountain Lion installation

    I have a mid-2009 13" MacBook Pro with 2.2g Ghz processor, 2 GB of RAM and 160 GB encrypted disc.
    After installing Mountain Lion and the recent upgrade OS X 10.8.1 (12B19), the system runs noticibly slower than with Lion, which ran slower than the previous version.  This shows up in opening and closing programs, rate that drop down windows appear when something is clicked on the task bar,  rate that windows open and close, rate that the dock comes up and the icons expand when the curser is moved over them, etc.  
    Due to my type of work, I need to encrypt the disc.  I know this is costing me some speed.  I unencrypted the disc and it ran noticably faster, and when I re-encrypted it seemed to run faster than before unencrptying and re-encripting.  I have repaired permissions and verified the disk OK.
    Somewhere in the build up to Mountain Lion release I thought I read where 4 GB of ram was recomended for Mountain Lion, allthough now the specs indicate 2 GB is OK.  In activity monitor, the pie chart for system memory seems to always remain less than about 40% of active memory (yellow).
    What recomendations does the community have to increase the speed of operations back to when this system was new?
    Dave

    I was having the exact same problem.  My MacBook Pro was seriously close to unusable how slow it was.  On a different thread, someone recommended I reset the VRAM and PVRAM (not sure about those initials).  Shut down computer.  Rebooted while holding down Command-Option-P-R all at the same time until I heard the second startup tone and then released.  I noticed an improvement in performance immediately.
