If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the startup drive, or some other hardware component, is failing. Back up all data immediately, then run Apple Diagnostics or the Apple Hardware Test.
Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly.

  • When I enter the website, Firefox stops responding and I have to end the process from the Task Manager. How do I solve this problem?

    I am running Firefox 4.0 beta 7 on Windows XP Tablet Edition OS. When I enter this site using Firefox, the browser stops responding and I have to end the process using Task Manager. However, when I open it with other browsers such as IE8, I am able to view the site as per normal. This only happened when I updated my browser to Beta 7 and I did not have such problems in the previous betas.

    There is [[Flash]] content on that page.
    Do you have a problem with Flash on other websites?
    Create a new profile as a test to check if your current profile is causing the problems.
    See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
    If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

    Dear Adobe.
    Yesterday I installed the latest version of Flash Player that auto appeared on my screen. Ever since I can not play video, and my system has become painfully slow. I have Mac OS Lion 10.7.5 and software is up to date. Before this everything was running beautifully. Can you please provide a link so I can uninstall the latest version only. Thank you. Stephen Kress. Melbourne. Australia

    When you run the uninstaller, it will uninstall all Flash Player versions.
    If you want to revert to an older version after that, get it from http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html

  • I am running OS X Yosemite on my four year old MacBook Pro which has become progressively slower and is loaded with applications I no longer use. I plan to start afresh by formatting a new 1TB SSD as a boot disk and reinstalling Lightroom 5 and PhotoShop

    I am running OS X Yosemite on my four year old MacBook Pro which has become progressively slower and is loaded with applications I no longer use. I plan to start afresh by formatting a new 1TB SSD as a boot disk and reinstalling Lightroom 5 and PhotoShop CC.
    Is there a list of the files and/or folders that contain Settings and Preferences which can be copied from the old system to the new?

    with your cc apps you should try to use the sync feature.  that's never worked consistently for me, but when it does work, it's helpful.
    there are preference folders and presets and settings that you could copy but you're better off installing fresh because a common problem for people with adobe program issues is a settings issue.

  • My mac has become very slow and crashes frequently after installing Lion

    My mac has become very slow and crashes frequently after installing Lion. I have a 4 GB DDR3 ram and 2.4 GHz Processor. The Mac was running just fine on Snow Leopard. Has anyone else faced this issue?
    Any suggestions on how to solve it?
    Thank you
    Kimberly M. Noronha

    I refer you to the TM expert
    http://web.me.com/pondini/Time_Machine/14.html
    As a extra precaution I would copy the user file folders of Music, Documents, Pictures etc to another external drive and disconnect, just in case.
    Always maintain TWO backups of your data at all times, since your messing with one, you need another until your back at two again.

      Restart the computer.
    Reset Safari.
    Click Safari in the menu bar.
    From the drop down select "Reset Safari".
    Uncheck the boxes beside  all items.
    Just check the box beside “Remove all website data”.

  • I am using iphone 4s ios6.1.2 ...my iphone has become too slow once i have updated from ios 5.1.1..can anyone help me to make my iphone perform batter

    Standard troubleshooting...
    Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
    Remove all apps from Recently Used list...
    - From any Home Screen, double tap the home button to bring up the Recents List
    - Tap and hold any icon in this list until they wiggle
    - Press the red  to delete apps from this list.
    - Press the home button twice when done.
    If still a problem restore with your backup.
    If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
    If still a problem, it's likely a hardware issue.

    I have an IMac and opened an email that may have been infected with a virus. How do I check my IMac for a possible virus? What does PPC mean?

    You would be better posting this in the Lion forum.
    https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion?view=discussi ons
    It's possible you email contained a virus, but unlikely.  There haven't been any reports of email viruses effecting the mac. 
    My understanding is the Apple provides security updates for all malware including viruses.
    There have been reports of a --
    -- Phoney virus checking program
    -- flash malware.
    ppc -- Power PC.   An older computer processor used by Apple.  Last Mac shipped with PPC was in 2006.
    I've read about two virus checking programs for the mac. One is clamav.  The rest are either junk or malware.

    houseofrest,
    According to this page, you can use it for CC:

    Or you can buy CS6:

    Hi Deb,
    Please accept my apologies for the inconvenience so far.
    I am not sure if you already tried this, but in case not, try to update Muse via Creative cloud directly.
    Start creative cloud application manager, if you dont have it, you can download it from here,
    Adobe - Adobe Application Manager : For Windows : Adobe Application Manager
    Login using your adobe id, once you are in, switch to Apps, and you should see the Update for Muse, click Update.
    Let me know if you get any error or warning.
    Thanks.
