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.

  • 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!

    Hi my name is Amit, after upgrading to OS X Maverick I often have problem of my Hot corners stop working after a short period of time.

    Right-click or control-click the line and select

    from the contextual menu.* A folder should open with an item selected. Move the selected item to the Desktop, leaving the window open. Log out or restart the computer and test. If there's no change, put the item you moved back where it was, overwriting the one that may have been created in its place. Log out again. Otherwise, delete the item you moved.

  • 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:

    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 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?

  • Corners stopped working

    My corners have suddenly stopped working. When I go to System Preferences-->Expose-->Active Screen Corners, they're still set the same way they were before they stopped working. Help!

  • HT2452 my imac keyboard has stopped working? help!!!

    my imac keyboard has stopped working??? help!!!!!

    My keyboard just stopped working out of the clear. One minuet OK next it was dead. No little green light at all. New batteries did not help.
    FIXED THE PROBLEM!  I took a small piece of aluminum, made a little ball out of it and dropped it down the tube where the batteries go. Replaced the batteries I had just used......little green light comes on and the the keyboard functions like always.
    My guess is after a few years the contacts oxidize a bit and don't make contact with the batteries on the bottom of the tube. Give it a try.

  • Getting Hot Corners to work with Captivate 6 Recording

    I've been having trouble getting hot corners to work when I'm using Captivate 6 for desktop recordings. I've tried telling the program to record a custom resolution that is slightly smaller than the screen size to see if that would help, but neither that or full screen recording fixes it. When I mouse into the corners during a captivate recording nothing shows up, but if its not recording they work fine. Any thoughts?

    Hello,
    Welcome to Adobe Forums
    Do you have Windows or MAC ?
    Did you try a different user account on your computer for recording ?
    Which recording option are you choosing ? (Video Demo, Automatic Recording or Manual Recording)
    Could you upload some sceenshots to elaborte your issue ?
    Thanks,

  • Hot Corners not working after using Call of Duty 4

    So I have noticed that Hot Corners are not working after i use COD4.
    I know that the game uses different resolution and somehow interupts the hot corner software. Buty why and how I dont know.
    I very often close COD4 by using Cmd+Q (or something like that)... But it doesnt matter if I quit it the "real" way. Hot corners still stops working after I use it.
    Hot corners works again if I reboot my iMac and also if I have used COD4 then go to System Preferences and Hot Corneres and make one change there.. then it magically works again.
    Does anyone have any definate solution for this.
    PS: I have an iMac 3.06 GHz Intel Core 2 Duo. 4GB 1067 MHz RAM and Lion 10.7.3.
    I also have a Macbook Pro with the same problem.... and both computers running Lion OSX and are always updated....
    Peace

    Does your 8600M GT have 128 or 256MB VRAM? Both versions shipped with that model MBP. The game sysreqs says that, while 128 is minimum, 256 is preferred. We all know what "minimum" means in software advertising.
    Have you downloaded the SL Graphics updater?
    http://support.apple.com/kb/DL1083
    It's supposed to fix certain games but it's worth a shot.
    I'm surprised that the temp doesn't change. Even running the COD2 demo on my Late 2007 2.2G with 2G RAM and the 128MB version of the 8600, temps go up to 160-170F. That was under 10.5. Just upgraded to 10.6 Sunday, so I guess I should check COD2 again, because SL seems to run cooler on my MBP.

  • Imac headphone jack stopped working!?

    i have a 2.4GHz intel imac that is only about 6 months old and i had a headphone extender plugged into the headphone jack outlet on the back that i never touched. i unplugged it yesterday and re-plugged it in today and now the sound is not going through the headphone jack at all. i've tried using different sets of headphones without the extender, i've unplugged and plugged all cords, re-booted, etc. to no avail. i'm really frustrated as this computer is basically brand new! and i'm guessing to replace the jack is going to be a big job. has anyone else experienced this or know of a way to fix? i haven't run any disc utility programs...

    I just bought a brand new 24" iMac and the jack worked out of the box for about 1 week. Then yesterday it stopped working. I did some research in these discussion threads and found one about using a secondary cable between the external speakers and the imac. So, I plugged in my Monster cable splitter for sharing your headphone jack with a friend. The connection was more secure than when the speakers alone were plugged directly in. The Monster cable had not static or wiggle. Everything seems to be working again. So it appears to be a defect in the headphone jack tolerance in the iMac. I've tested the external speakers in 2 different ipods and it works fine with both of them.
    It ***** to have your new computer not work well out of the box, so if you truly want a mint machine, contact Applecare and see about replacement. Or you can try this easy fix. We'll see how long it holds up!
    Good Luck!

  • IMac External Monitor stopped working

    I have an Intel based iMac and have been running my old 17inch apple monitor as a second display for over a year now. For no apparent reason today the monitor stopped working. The screen just appears black. there is power getting to it as the power light is on and the computer detects the display fine. I can even move objets to that monitor, I just cant see anything. Any helps would be appreciated.
    thanks
    Joe

    Yep, have the same problem using a 3rd party cablesson mdp-hdmi adapter. Everything worked fine until quite recently. I have tried pretty much everything to fix it but nothing seems to work. I'm almost convinced it's an OS problem, as everything works fine when I boot into my windows bootcamp partition.
    Apple, please get this sorted! I'm reluctant to shell out $35 only to find that I have the exact same problem with the official adapter. Though I probably will anyway because I urgently need to get my display working again.

  • IMac sound intermittently stops working

    I have an intermittent sound problem with my new iMac.  Periodically, sound stops working in certain user accounts; but, works fine in others.   The only way to temporarily resolve the problem is to reboot the computer.   Haven't found a pattern to when sounds stops working... please help.

    I have the same problem on my 21" iMac purchased in early 2011.  My wife's user account is fine.  The settings in System Preferences and Audio MIDI Setup are correct.  I've tried deleting relevant plist files, all to no avail.  Any ideas, anyone?

  • Imac 20" just stopped working - just switches off

    Hi I'm running an imac 20" intel and its about a year old - I've had no problems with it until now - I installed ilife 08 last week and also added a 4 port USB extender cable but it worked ok for a few days after.....Now it has suddenly started turning itself off and I have to unplug the power cable before turning on again and even then it starts to boot and then switches off........fortunately I backed everything up the first time it did it but is it the power cable or a computer issue? I'm in Singapore...
    Thanks for the help
