Hot corners regularly stop working

My hot corners are correctly assigned (from the previous OS) but always stop working after a while. This is corrected by a restart. Guessing that this is a bug in Mountain Lion and wanted to bring to your attention. Thank you.

Try this. In the Finder menu bar click on Go > Go to Folder and type ~/Library/Preferences. Highlight com.apple.screensaver.plist and remove to your desktop. Logout/Login or restart and reset screensaver preferences in Desktop & Screensaver in System Preferences. Click on the Hot corners button and reset your hot corners preferences. If this works you can trash the Preference file you moved to the desktop.

Dock hiding and hot corners no longer work

I am not sure exactly when it began, but for the past 2-4 weeks, my hot corners and dock hiding have been very erratic. At seemingly random times, all the sudden my hot corners stop being active, so when I move my pointer to the corner, the designated task whether it be dashboard, Expose, screen saver, etc. as selected in preferences no longer activates. Dock hiding stops working as well. The dock hides, but when I move my cursor over where the dock is parked it doesn't appear, it stays hidden. I can click command alt d and the dock will appear or disappear, but will not appear by just moving the cursor to the side of the screen where the dock is parked. I have not added any new software lately other than Apple OS 10.6.4 and whatever Safari, iTunes etc updates that keep coming at along at pretty regular intervals. Interestingly I have an iMac at work and at home, and they both are misbehaving in the same way. They are similarly populated with software, although not exactly. When I update one, I update the other. Both started misbehaving at about the same time.
I have rebooted- sometimes works, sometimes not. I have trashed the dock and finder plist- works for awhile, but problem always returns. I have reset the PRAM- works for awhile, but problem always returns.
Any thoughts. I like being able to hide the dock to gain that extra bit of screen space, although the command alt d, is an adequate if not ideal work around. But I really like the hot corners, and I do not know of a work around for that problem.

The university requires all computers to have anti-virus software and recently switched to Sophos from Symantec, in July I believe. That was a new software install. Since it just works in the background and I never actually access it, I had forgotten about that. I hope that is not the problem, as I am required to have antivirus software.
And no I have not created a new user to log in. It is erratic enough that I don't know how long would have to be on to see if the problem recreated itself. Sometimes it seems like just minutes after I start the computer up and sometimes hours. Right now it is still working since starting this morning.

Personal Hot-spot has stopped working for no reason

I had a perfectly functional Person Hotspot (data tethering) feature with my Vodafone UK connection, and the data tethering plan I had enrolled proved more economical than those regular USB dongles. Recently, I upgraded my vodafone plan to allow for a higher usage - and somehow the person Hotspot just stopped working. Every time I navigate to the Personal Hotspot Button, the tab - which used to read 'Enable Personal Hotspot ON/OFF' - now reads 'Setup Personal Hotspot'. When I click on the link, it directs me to a Vodafone Iphone Advertisement page.
I contacted Vodafone officials, even personally visited their store and got a confirmation that the data tethering plan is active, and there should be no problem with my iphone's data tethering capability. The best advise they could suggest was to backup and restore the Iphone using Itunes. Well - I tried that as well, and still the problem persists.
Has anyone faced this problem before? Can anyone help - where exactly can I reset the Hotspot settings, or even enter it manually to get it working? I've tried backup and restore, reset cellular data network, Disable and re-enable 3G, ejecting and re-inserting Vodafone SIM........ The hotspot was a wonderful feature, would love to get it back.........!!
Thanks!

Thanks Dodie. My personal hotspot just stopped working. I use it all the time and it was driving me crazy having to connect via usb.
I have used the reset before and forgot all about it.
Simple fix, get it got it, good !

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 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?

Hot Corners do not work on second (extended) display

Hi all!
I'm using a 24" ASUS display to extend my MB's screen, when using it at home.
After upgrading to Snow Leopard, the hot corners still work with/on my MB's screen, but no longer with/on my ASUS-screen.
After defining the hot corners in the system preferences, everything works well, even with the second screen, but when I shut the MB down, and start it again on the next day, the hot corners only work with the MB-screen, and no longer with my ASUS-screen.
Sorry for my bad english, but I hope you understood my problem so that anyone might be able to help me, or at least share the experience...
Thanks!

No ideas?

Hot Sync just stopped working

I recently noticed that my Zire 31, which is linked to my Windows 2000 computer, has suddenly stopped adding any new dates to the handheld device. I can add them to the main program on the computer, the Hotsync button seems to work and it appears to being doing the sync but when you look at the handheld, there is no new information added.
I have not updated any programs or changed out any hardware. The Zire 31 was working fine then it stopped.
Any suggestions?
Post relates to: Zire 31

Hello..
Have you checked the conduit actions for your calendar if its set to do nothing?
simply right click on hotsync manager icon in your system tray then go to custom check if the action for your calendar is set to do nothing and if does change it to synchronize the files or Desktop overwrites handheld (if the most current information is in the Palm desktop)

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.

Why do hot corners break every time I wake from sleep?

Every time I open my computers, my set hot corners have stopped working. In the settings, they are still there, but I have to either change the settings and change them back, or use the terminal command 'killall Dock' to fix the issue. It's quite annoying to have to do this every single time I turn on my computer. Does anyone know a fix?

I have this same issue - after coming back from sleep hot corners stop working - this is a constant problem and I think having to type "killall Dock" is NOT a solution. I also have a rMBP with 10.8.2

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 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?
Re: Hot corners

Hot corners work for exposé but not for screensaver

There are several fairly specialized posts in these forums about hot corners, but my problem is a very simple one: whereas I can use hot corners to control windows, etc., I cannot make them work to turn the screensaver on or off. In the Leopard forum, there is a reference to an article in MaxFixIt, but it is only accessible by MacFixIt Pro subscribers (amongst whom I am not numbered). Were it not for the fact that hot corners seem to work for me as far as Exposé is concerned, I might have guessed that my problem is caused by the fact that the eMac has a CRT display and not a LED one. But the hot corners do work for Exposé, so that cannot be the answer. I trust someone will be able to find the correct answer and tell me how to make them work for the screensaver.

Further to my question, I think I need to be more specific. I have set the top left corner to start the screensaver and top right to disable it. There is no trouble with top left: the screensaver starts. But that is actually fairly trivial: I have it set to come on anyway after 3 minutes. But if I leave my cursor in the top right corner ('disable screensaver'), I expect the screensaver not to come on after 3 minutes; that is what 'disable' means. But it does come on: that is my problem.
Surely 'disable' cannot mean 'stop'? If one moves the cursor while the screensaver is running, it instantly stops anyway, so why use a hot corner? Surely it must mean 'do not start up after whatever time is normally specified', so that, for instance, one can watch a slide-show of photographs without interruption?

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.

NB205 Wifi Stops Working When Laptop Is Hot

Hi Everyone,
I have a NB205 laptop that's in great condition. I love it to death, but whenever the system becomes hot, the Wifi stops working. I usually have to restart the computer for it to work again. The problem seems to be getting worse. Even if the device is on a cooling pad, it seems to have this issue. The laptop, in my opinion, doesn't even get that hot for the issue to occur.
I sent the laptop to Best Buy for repairs, and after two weeks they returned it with absolutely no improvement in performance. Is there a driver or something that I can try downloading before I take it back to Geek Squad?

It's not losing connection to the router. It happens at all locations, so it's not the internet connection thats the problem. It's definitely an issue with the laptop itself. I have Windows 7 and upgraded ram.
It happens as soon as it gets hot. I can't keep it on my lap for more than 5 minutes without it becoming too hot (although it doesn't feel that hot compared to past laptops I've had) and then I just get a big red "x" on the wi-fi icon.
