Hot corners malfunction

Hi, My Macbook Pro is doing a wee bit of a malfunction on the hot corners. Most of the time it works perfectly. (I have set the top left corner to show all programs) But every so often, it puts the computer into sleep mode, (a full shutdown) and I have to go through the process of getting back on to wireless etc every time it does it. Sometimes this can be 4 or 5 times a day...I am doing a disk repair, but wondering if the problem exists for others too or if anyone knows how to fix it?  Thank you

Try deleting the System Preferences plist and see if that will solve the issue.

  • Dock, Expose, Hot Corners etc. don't work anymore! Solutions?

    Two days ago I decided to restart my Macbook. When the screen popped up it gave me the option of "Reopen windows when logging back in". I never noticed this before switching from Snow Leopard to Lion but maybe it's always been there. Anyways, as you know it is checked by default so I unchecked it just out of curiosity and restarted my system.
    When the system came back on, my desktop background had vanished, hot corners will not work, dock does not show up, and when I try to change any of these preferences they do not take. (i.e.-changing orientation of the dock from bottom to left, it simply won't let me select left) I can only open applications from spotlight, and when I mouse over an item now it turns the font white, which never happened before since I did not have it set like that. In addition, google chrome and safari both crash quite frequently since these mess-ups, and so I have resorted to doing all of my work from Firefox.
    I've read in these forums as well as other place on the web about this problem happening, but I have tried all of the remedies to no avail. In the past, the problem for users was a lot of the time caused by the use of a wireless mouse. However, I have never used a wireless mouse so this can't be the problem. I also went in to disk utilities and ran a repair, thinking maybe something might click but nothing did. I have restarted/shut down many times just to see if the problem has fixed itself, which it hasn't yet. I've gone into Activity Monitor and relaunched Finder several times, and also noticed that Report Crash is working super hard on the system for some reason. (Maybe because of many of my programs freezing and crashing?)  I also deleted many recent downloads, since I had one or two unfinished downloads and this had been the problem for one user inparticular...I did a "Secure Empty Trash" from the finder menu for these items. I also ran CleanMyMac and uninstalled a couple of applications that I don't use just for good measure...still NOTHING.
    I'm in no way an expert with computers, I just own a macbook and it's having problems. If you guys could lend your expertise as a last ditch effort that'd be great. I'd prefer not to take it to GeekSquad, Apple Store, or a repair shop because I'm a college student and I'm literally broke at the moment, so any remedies or ideas would take weight off of my chest.
    Thanks in advance-Jameson

    Also, this black bar shows up towards the bottom of the screen on the left side when it's on the apple loading screen. Not sure what it is...and yes I have also run system updates.

  • Screen Sharing and Hot Corners/expose bug?

    I tried searching but I came up with nothing. I have an iMac and a Macbook. On the iMac I have hot corners set up to use expose. On the bottom left I have it show the desktop and on the bottom right I have it show all windows. Now when I use my macbook to screenshare with my iMac and try to drag a file on the iMac, it activates one of the hot corners even though my mouse cursor is no where near either of the corners. If I deactivate the hot corners, I can drag just fine but I don't want to have to do that every time I use screen sharing. So this is making screen sharing pretty useless. Anyone else have this problem? I just submitted a bug report too.

    I have the same problem. Very annoying.

  • Having issues with two-finger swipe and hot corners. Help!

    I've lately been having an issue, where my two finger swipe will stop working. I also notice that 3 of my 4 hot corners no longer work, either. The only one that works is the top left. When I restart my computer, or change users, etc, it's fixed for a while, but then the problem will start up again in about an hour.
    I've tried the Software Update, and it seems everything is up to date. Any solutions?? I spent a good deal of money on this iMac, and I'm concerned there's something wrong with it.
    I have a 27" iMac, which I bought around November 2011. Software is OSX 10.7.5
    Thanks!

    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 in OS X 10.9 or earlier, 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.

  • Using my MacBook with a "docking station" setup issues with hot corners

    I have a 13" white 1.83GHz Core Duo MacBook. Came with 512MB of RAM, upgraded that to 2GB from OWC. then my HDD started to die, so while replacing that I went from the 60GB to a 120GB SATA 1.5 5400RPM HDD. This is my main system, I use it for both work and home. At work I use the laptop display, keyboard, and touchpad. But at home, I use a 19" wide via Mini DVI to VGA, one of those new bluetooth apple keyboards (just got it, one of the best keyboards I have ever touched), and a USB wired Microsoft mouse.
    The issues I have been having are as follows: I get home, plug in the power, video, and mouse. then click a key on the keyboard and it will wake up. But half the time my hot corners don't work, and I am unable to see other PCs on my network. I reboot and these issues are fixed. Then I leave from home, and try to wake up the Book at work, half the time it wont wake up, and when it does, same issues, hot corners don't work, magnify doesn't work. Can't see other PCs until I reboot. I have a short drive, and I prefer to just put it to sleep.
    One other issue. I play World of Warcraft on this system, and in the last couple of weeks, it will produce system lag. to the point where it gets really hard to keep playing. Other people I know have identical systems that play it just fine. Any ideas?

    Yes, the use case you describe is possible.
    If you buy the Lenovo fingerprint keyboard, then you are buying something that has been tested with ThinkPads and we provide a driver for Win8/Win8.1
    If you buy some other fingerprint keyboard, we can't guarantee whether it will work or not.  At least, make sure there's a Win8/Win8.1 driver for it.

  • My macbook pro started acting strange after a safari reset. the mouse no longer: animates the dock, activates hot corners or selects pages from the 'top sites' page.

    my macbook pro started acting strange after a safari reset.
    the mouse no longer: animates the dock, activates hot corners or selects pages from safari 'top sites' (without a hassle). attempts to reset dock and hot corners from preferences has been fruitless
    the mouse also gets 'stuck' in logic precipitating force quits.
    i run osX 10.6.8 on a 2007 macbook pro that has had 2 motherboards replaced autumn 2010.
    my troubleshooting has been: restart, pRam and safe boot, also checking a 'test' account to find the same issues extant.
    pRam restart caused airport to quit and say there is no airport card, and wouldn't respond untill another reboot.
    macbook pro 15" 2.4 GHz intel core duo.2 GB 667 MHz DDR2 SDRAM.
    i have treated this book with care, yet run logic pro studio to the limit of this book's abilities.
    what shoud i do?

    You don't say which year you have, however...
    ...there are known problems with the mid-2010 models (see http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US) as well as early and late 15" 2011 models (see https://discussions.apple.com/thread/4766577?tstart=0).
    Apple has taken ownership of the problems with the 2010 model but, unfortunately, the free logic board replacement for that model has probably long expired for you - three years after date of purchase.
    One the 2011 models Apple has admitted no defect. You'll just have to skim the articles to get an overview of the problems that people are having (usually showing up as screen glitches at first and then going downhill from there).
    Good luck,

  • Hot Corners: Display Won't Sleep

    I have, for a long time, used hot corners to put my MBP display to sleep. I have things such as backups run while I sleep, so shutting down MBP or hybernation is not an option. Since the last OS update, envying the display sleep hot corner only works for less than a minute before the display wakes. I have had no problems with display sleep on my iMac. Does anyone have a suggestion to a fix? Thanks.
    Alice

    I'm running the latest OSX, and have the same problem.
    The screen saver, or sleep, set in hot corners, only runs for 10secs at best.
    Obviously something is disturbing the mouse. Could it be the uneven surface of the desk playing havoc with the laser? I'm not using a mouse pad, just using the desk surface.

  • IMac Hot Corners stopped working

    I have a wireless mouse and keyboard. Mouse has new batteries. Hot corners worked yesteday but no matter how I set them in System Preferrences, they do not work today. Any suggestions?

    I was about to try your suggestion, however the hot corners have started working again. I don't know why... Hopefully, whatever it was has fixed itself.

  • Moving tabs from one window to another makes the new window vanish. I have hot corners enabled so when I move up to the right corner of my display I can see all my open windows but when I click on the tab that I moved to make it its own window it vanishes

    Moving tabs from one window to another makes the new window vanish. I have hot corners enabled so when I move up to the right corner of my display I can see all my open windows but when I click on the tab that I moved to make it its own window it vanishes

    I came up with an alternative solution.
    Instead of actually trying to move the JInternalFrame from one JDesktopPane to another, I added a single, maximized JInternalFrame to the left side. When one of the right side frames is to be docked, I merely copy its ContentPane to the single JInternalFrame on the left, set the original to be non-visible, and adjust the properties of the JSplitPane to make the "docked" frame appear.
    When the "close" button on the docked frame is pressed, I simply undo this procedure to "undock" the frame and redisplay it on the right-hand side (with its content intact from the docked frame, but in its original position).

  • Can I use Hot Corners to make the display sleep immediately?

    I have Hot Corners set up so that the screen-saver kicks in as soon as I move the mouse to the top-right corner. However, I'd really like to be able to make the display sleep immediately, rather than show the screen-saver first... can I do that? There doesn't seem to be a Hot Corners option for "Display sleep".

    Hi Garth
    That can be set using expose.
    Open up preferences /dashboard & expose.
    Click on one of the buttons to set your option to start screen saver by choosing the corner you wish to use.

  • Hot Corners don't work/Click and drug doesn't work

    Hi, I have two computers, iMac 2008 desktop (OS X 10.9.4 ) and Mac air book.  Recently about  3 weeks ago. Both of them started having issues. When  i will navigate in any corners they would not work (neither Screen Saver, nor All Applications) none of the hot corners that I set up work. However, at times they would work but really slow and my computer kind of like logging (getting supper slow)  Another thing happened to both computers: When I click and drug any file from one folder to another it just would not do. the file I click would get hi lighted stick to my mouse pointer and the computer would just freeze. However, when I do copy and paste a file it works.  I upgraded to Yosemite and even that did not help.   I reinstalled OS X from my old time machine back to  OS  X 10.9.4 and the problem still persist.  Is this disease  a nation wide ???
    Please help....
    did anyone else had something ???

    Please post the EtreCheck output

  • Hot Corners Stopped Working

    Strange, up until yesterday my hot corners were so sensitive I was constantly activating them accidentally; now they are not activating at all.
    System Prefs>Desktop & Screensaver>Hot Corners is not doing it for me! Reboot?

    Hi David!
    That sounds really strange. Can you think of anything you might have done/changed on you mac before the hot corners stopped working? Any new applications installed, for example?
    Maybe a resart might work, if you haven't done that already. Also, try using Disk Utility (found in HD>Applications>Utilities) to "Verify Disk Permissions" and "Repair Disk Permissions" on your Hard Drive. That might sort out any little bugs which might be stopping your hot corners from working.
    I take it, that your 'Hot Corners' Preferences are properly set to what you want? What ahppens if you put them back to "Nothing", restart and then put them onto what ever triggers you want?
    I hope that helps!

  • Hot corners stop working with USB Mouse?

    Hi,
    pretty simple one this (to explain anyway)
    Hot corners don't work with a USB mouse on my 10.10 MBA.
    If the USB mouse is plugged in, hot corners do nothing (Whether I use the mouse, or the track pad to move to the corner of the screen)
    If i unplug the USB mouse, they work fine again.
    I have rebooted and unplugged and replugged the USB mouse to no avail.
    Any ideas?
    Thanks!

    Have you tried another USB port?

  • My two right hot corners stopped working

    The two right hand hotcorners of my Macbook Pro stopped working 2 days ago. The left hotcorners work fine, as the right ones did, but suddenly nothing. I already tried the thing with erasing the dock file from the library and restarting the laptop, but it didn't help. I'm a little frustrated,,,is this a bug or what?

    Try a SMC reset:
    http://support.apple.com/kb/HT3964
    Also go to system preferences>Desktop & Screen Saver>screen saver tab, in the bottom left corner click hot corners and see if they are blank, somehow it was dumped and try resetting them to your preferences.
    Try this before the smc reset. Sorry I had to fire up my Lion machine to check this.
    All the best

  • Hot corners do not work. Is there a plist that can be deleted to rectify this?

    Is there a plist that can be deleted for hot corners?  I cannot get them to work at all.  Thanks for any help.

    "The easiest way to get the hot corners temporarily working again is to launch the Terminal.app and type "killall Dock" in." quoting Michaël Betsch
    I tried this but it still doesnt work. Just to clarify, i'm using a MacBook Pro MAC OS X v10.7.2 Lion.
    I even tried changing the hot corners and changing it back. But all the 4 corners still doesn work.
    I encounted this several times already. I tried rebooting my mac and it worked after startup.
    Is there a better solution to it besides rebooting my laptop?
