my mac keeps freezing on highlighting only way to get out of it is to force a power down and restart

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 the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • My Mac keeps freezing in the middle of applications (most notable Safari) requiring me to shut down and restart.  It also freezes during video playback (online and using Quicktime).  Do I need to wipe and reinstall OS?  I'm thinking I have a virus........

    Please help!!  It's driving me nuts.  I've reinstalled the OS via the disc about 3 times so far, but haven't yet erased the drive (and am seriously considering doing so).  I barely have any files on my HD because I run everything off of external drives (after losing a TON of stuff after my Mac crashed in the first 3 months of having it).  I bought the computer in 2007 and was running Tiger.  I passed on Leopard but gave in for Snow Leopard because I wanted an iPhone and iPad.  When I installed SL, I had to reformat the HD and made it Journaled......it's been acting ******** ever since. 

    First you don't have a virus because none exist for OS X. So you can stop worrying about hat. If you recently got a warning about a Virus and accepted downloaded some software then you fell for a Trojan. Here is an article about that and how to rid yourself of it.
    If you did not download anything like that then doing a Erase and Install would be the way to go. Here is a video that will show you exactly what to do.

  • I am having trouble with computer freezing, spinning wheel.  The only way to get out is to manually shut off computer and reboot.

    The issue usually occurs when computer goes into the screensaver mode.  When this happens, none of the keys are opperable and the round wheel/ball just continues to spin.  The only resolve is to manually shut down the computer witht the button on back of the monitor/hard drive.  Not sure if this is bad for the computer to shut down this way or not.

    I starting having this "colored spinning wheel" problem too! It started about two weeks ago and like the others, every time I go into my Yahoo mail, I get the spinning-wheel and the only way out is to "X" out of the site. Sometimes I can make it through a few notes, other times the problem starts as soon as I click on the first note. I searched google a few days ago and saw a response to this problem that said I should "uncheck" the 3 items in the "Auto-fill" preferences in Safari (Safari-Preferences-Autofill) and that should help. It did not. I also went in and deleted cookies, cache and history, but that didn't work either, or if it did, it only took a few clicks to experience the problem again. One of the times I went in to delete cookies I noticed over 100 cookies and other website data stored and I had only been on perhaps 2 or 3 sites (CNN, google and yahoo and perhaps Apple), and I never click on the adds. Don't know if there's any significance to this but I thought that was an awful lot of "cookies" for just a few clicks after previously deleting cookies. Also, I believe I have the latest version of Yahoo mail. I actually have 2 Yahoo accounts and the spinning wheel is a problem with both of them, same for my wife. Any help would be very much appreciated.
    I have a MacBook Pro purchased last December with Snow Leopard 10.6.8, Safari version 5.1, an Intel core i5 processor, 4 GB of memory and a 320 GB HD with very little loaded on it.  

  • Firefox 5.0 stalls while watching videos (at least) and the only way to get it back working is to close it and restart it, and this is not right !

    I have been using Firefox 5.0 for the past few days. I have been experiencing the following error : I watch videos and suddenly, the video stops. From that point, it becomes impossible to open new tabs, especially, I tried to use the search box (with Google or Yahoo) on the top right of the page and got no result.
    However, if I close the browser and restart it, Firefox works again, until it drops again. I therefore have to close it and open it again every 5 minutes to read a video (the problem also appears when not using the video). The only thing that might cause this that is not Firefox could be my latest upgrade from Xmarks, however I disabled the thing and still got the issue.
    I would like to uninstall Firefox 5.0 from now and put Firefox 4 at least until the browser is more stable, but how do I do that ?

    Hey ppgg,

  • Since I upgraded my 5c to iOS 7.1.1 my apps randomly stop working. The only way to get them to work is to power off and on. Any suggestions?

    My apps including safari are randomly not able to access their servers. Then my wifi goes to E. I have to power off and on to make them work. What should I do?

    Double-press the HOME button. Then flick each screen image up to terminate the application and free up its memory. When all apps have been killed. reset the phone by holding the HOME and SLEEP buttons at the same time until an Apple logo appears.

  • The round button that allows me to get out of an app or to move or delete apps has stopped working.  Once I am in an app the only way to get out of the app is to power off my ipod completely.  Help!

  • Firefox just updated to 5.0.1 when it opens it opens two tabs, one a restore session tab and the other Firefox home tab. Nothing appears in the restore tab and everything freezes. Only way to get out is to ctrl, alt, del.

    After updating to Firefox 5.0.1 and trying to open Firefox, it opens two tabs. One is the restore session tab and the other is the Firefox home tab. Nothing opens in the session restore tab and once the Firefox home tab loads the browser screen freezes with no crash ID's listed. The only way to get out is thru the task manager and ending the process. Firefox worked fine before updating.

    Hi glivezey,
    Try typing ''about:home'' into the address bar. Is that the page you are looking for? If so, go to ''Tools > Options > General'' and save it as your homepage. If that home page doesn't show up the next time you start Firefox, you should look at [[Preferences are not saved]].
    Hopefully this helps!

  • Just picked up my Macbook Pro (Oct 24th) to find that it keeps freezing on me - only way out is to crash it via the power button. No particular pattern to it.  It can happen on opening, or clicking on Safari - or when it's backing up on the TC.  Ideas?

    Picked up my new Macbook Pro Retina display on October 24th (2013).  It runs Mavericks.  Keeps freezing on me - with no pattern to it.  Sometimes when it's backing up, sometimes when it opens, sometimes when I click on Safari.  Only way out of the probelm is a crash shut down using the power button. Nothing else works.  Anyone found a fix to this yet?

    Safe Mode deletes some system caches that may help.
    Startup your Mac in Safe Mode
    A Safe Mode boot takes longer than a normal boot so be patient.
    Once you are in Safe Mode, click Restart from the Apple () menu.

  • I get a pop up window when leaving a site asking if I am sure I want to leave, the only way to get out is kill Firefox in task mgr but FF restarts the lockup

    On some sites I get a pop up window asking if I am sure I want to leave the site. The only option is to click on the pop up, nothing else works you cannot use back or even shutdown FF. I have to shut down with task manager, but when I restart FF it goes back to the locked up page.

    If you want to change how Firefox starts up after a crash, you have the option to have Firefox show a list of windows and tabs. Then you can deselect the tab you do not want opened again. Here's how to change the setting:
    (A) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
    (B) In the search box above the list, type or paste '''sess''' and pause while the list is filtered
    (C) Double-click the '''browser.sessionstore.max_resumed_crashes''' preference and enter 0 (that's a zero) and click OK.
    Note: Please don't customize any other sessionstore preferences to zero, or you might lose the ability to recover your closed windows and tabs.

  • Is there a way to get out of using RSS in mail.app and go back to Safari?

    Hello,
    I am a big RSS user and have a pretty huge and unwieldy subscription list. When Leopard shipped, I started using mail.app to read my RSS. I went so far as to delete all of my subscriptions from Safari and rely entirely on mail.app.
    As some of you may have noticed from other threads in this forum, RSS in mail.app seems to be not ready for primetime. Specifically, if I leave mail.app open for more than about an hour, the RSS feeds stop updating entirely or update sporadically. It is at this time when I will also invariably find a Database.sqlite3 file in my trash can (which prevents the trash can from being emptied, too).
    If I restart mail.app, the feeds start updating again BUT INCLUDE HUNDREDS AND HUNDREDS OF OLD ITEMS. This happens every time I restart mail.app now. I have read all of the other threads that suggest that perhaps dot mac bookmark synching is to blame. This cannot be in my case since I have it all turned off and am not a dot mac member. I have no plugins installed in mail.app or safari.
    I have come to the conclusion that RSS in mail.app is too buggy and unreliable to be used and I would like to go back to Safari. The trouble is that when Leopard shipped, the idea of RSS in mail.app made perfect sense to me and I got so enthusiastic and "there's no going back" that I deleted my enormous amount of RSS subscriptions in Safari. Is there anyway to export my RSS subscriptions from mail.app so that I can import them into Safari? I REALLY don't want to try and add them again one by one.

    here is a link to macosxhints.com that tells you how to output all of your feed URLs to a terminal window. from there you can cut and paste them into your new feed reader of choice...
    http://www.macosxhints.com/article.php?story=20080319094830396
    and if you are in the marked for a new reader may i suggest David Watanabe's excellent NewsFire. he had just recently made it totally free as a gift to the macintosh community.
    best of luck.

  • My desktop (M73 SFF) keeps power down and restart while playing games

    I bought M73 small form factor with Intel core i5-4570 and 4GB RAM with integrated video in Sep. 2014.
    Recently, it keeps being shut down while playing game (starcraft 2).
    Is this related to hit sink issue? graphic? or both?
    How do I fix this problem? Should I replace hardware?
    Thanks!

    Probably heat related.    You can monitor the temps using Hwmonitor or SpeedFan.    Your BIOS may have a fan setting, that you can adjust for better cooling performance (acoustic performance is the default.)   And check that your BIOS and drivers are up to date, using Lenovo System Update, including the optional ones.  

  • My phone goes off in any time of the day and the only way to get it back is through pressing and holding of Home and Sleep button together

    Like I said in the subject line:
    My brand new iPhone 4S/32Gb goes off in any time of the day and the only way to get it back to live is through pressing and holding of the Home and Sleep button together for 5-10 seconds.
    Does anybody have that kind of problem as well?
    Thank you.

    I restored it on I tunes as well did something on the phone. The lastest seems to have helped it but I haven't used it much yet!  Thanks for the help & I'll let you know!

  • No way to get out of App

    Hey guys,
    Some of my apps won't give me a way to exit the app.
    The reason is that, for apps like the reader or calendar, when I point towards the top right corner, the x for close doesn't appear. Neither does the last used app when I point towards the top left corner, or the task bar when I point towards the bottom
    of the screen. The only way to get out is by pushing the windows key or alt tab. 
    I want my close x, task bar and last used app back - How can I?
    Thanks! 
    Tobi

    Hi Tobi,
    Alt+F4 will also completely stop all processes associated with an app, if you don't see the Close button in the title bar, you might don't have the latest update to Windows 8.1 and Windows RT 8.1.
