OS X :: Command+tab Switching Stops Functioning / Shortcuts Stops Working
Nov 22, 2009
On a day-to-day basis I run: Adobe PS, INDD, and AI, Microsoft Entourage, Firefox and iTunes. Just recently, after an upgrade to Leopard, I added Things and Simplify Media to the list.The problem that happens before (on Tiger) and now (on Leopard) is command+tab switching stops functioning and Expose hot corners and shortcuts stop working.
I'm pretty sure this isn't a Finder crash because before, on Tiger, I could quit+restart Firefox and everything would be back to normal. Almost as if some shortcut had causes the system to act differently or there was some app dissonance?
But now, with Leopard, nothing I quit will cause these two features to act properly until I do a restart. Both features (command+tab switching and expose) are very necessary for my work flow. I have checked SysPref to make sure keyboard shortcuts are default and Univeral Access to make sure assisted devices is turned off.

Somehow my keyboard shortcuts got switched, and the dashboard shortcut is now assigned to the F12 key. It says that in order to switch a keyboard shortcut, just double click and hold down the new shortcut key, but that's not working!

I'm yet to figure out a pattern, but my Macbook Pro's keyboard will just stop working for several minutes at a time at random points in time...Even if I hit caps or num lock, they don't turn green. Sometimes it'll just happen once every few hours, but I was in class the other day and it would work for a minute, then not work for a few, than work for another minute, etc.

I've noticed that occasionally my IR sensor stops working, and no longer responds to changing the volume, skipping the track in iTunes, etc. It can be resolved by going into Security prefs, disabling and re-enabling the IR sensor. This is annoying, however, and I'm wondering if it's a known issue that might be fixed.
I noticed that when you disable and re-enable the IR sensor, the last few remote button pushes you made while it was broken come through in a burst.

I got my computer yesterday, it's a iBook G4 OS X 10.5.8. The charger worked fine until around six o' clock. Then it wouldn't charge. We switched the power pack and it worked for an hour or so, and then the same thing. What can I do? I CANNOT take it to be fixed.

I've read another strand about the problems with the gaps when PowerBooks are closed, but does anybody know how to fix the clasp when it stops working? The hook still comes down and "hooks," but as soon as I let go of it, the top pops back open. It's been getting progressively worse over the past three weeks or so, but now it won't stay closed at all. It's not a big deal when I power the thing down, but I can't just close it and put it to sleep now. (Especially one's that don't break the bank!)

I'm running 10.5.2 on a 2GHz C2D BlackBook. Recently I've encountered 3 symptoms that suggests Quartz Extreme stops working after the computer's been running for a while (and by a while, I mean it could only be a couple hours).
I've recently (a few days ago) set my desktop picture to change every minute. It's supposed to fade smoothly between pictures, and it did for a while, but then eventually I noticed the fading transition had stopped and the pictures were just switching without any kind of transition. The problem was resolved after a restart.
I don't use iMovie often. But I opened iMovie '08 yesterday and I got the following error message: "iMovie requires a graphics card that is compatible with Quartz Extreme. One or more of your graphics cards does not support Quartz Extreme." My only option was to quit iMovie. I noticed my desktop picture was also not doing the transitions any more. After a restart, both problems were resolved.
Today, I got the same error message in iMovie and the desktop isn't transitioning again. I haven't restarted yet, but I assume it will fix itself when I do. Also, I tried adding a widget to my dashboard to see if I get the ripple effect, to test my theory that Quartz Extreme (or is it core image, or core graphics?) stops working after a while. I did not get the ripple effect I usually get when adding a widget.
Since I just started using the changing desktop feature and 10.5.2 is a new update, I don't know if one of those could be causing the issue. I'll try turning off the desktop transitions and see if it continues.

My macbook pro keyboard and my silver Apple bluetooth keyboard (primary keyboard) randomly stop working in Finder can anyone explain? Heres the details:
I usually use my wireless keyboard, and when this happens the keyboard keeps working with everything else, and only stops working in Finder i.e. I can't edit the names of files or even click through files with the arrow keys. (the Macbook Pro keyboard also stops working-only in Finder-during these times too as I just tested..)
Also, Finder keeps working its not frozen or anything, I can click around in it with the mouse and open files/apps, etc.
This has only happened approximately 3 or 4 times (I've had the keyboard since the new ones were released and the computer for 1.5 yrs)
Lastly, when I restart the OS (10.4.11) the problem disappears for a week or more..

So to preface my problem let me just say that ive got my own macbook which works on the same wireless network with no faults at all, so i assume its not an error with the networking hardware.
For xmas i bought my parents a macbook, recently (not sure how recently as theyve only just told me its happening) they can be browsing the web then all of a sudden the internet takes ages to load, it stalls on 'trying to connect' for a long time (40+ for each web page).
Ive tried using firefox and the same thing happens so it looks like its not safari specific, during this time i cannot ping [URL] through a terminal either or if i can the response time is unbelievably slow.
Now, ive tried disabling ipv6, ive set the dns servers to opendns and none of this has fixed it. if i click on the airport utility and turn it off and the back on it fixes the problem for a short period of time before it happens again.

I have some strange problem after updating my MacBookPro4,1 to 10.5.7. After a while (can be a few hours) the trackpad and keyboard stop working. When I then put the MBP to sleep and wake it up, both work again but only for about maybe 5-10 minutes. This can be reproduced (put to sleep, works for 5min, put to sleep, works for 5min, etc.) When I reboot it works again for some hours.

I have noticed that my keyboard will randomly stop working after switching Spaces or using other shortcut keys. When I hit the CMD-arrow key to switch spaces, the Spaces box that shows which space you just moved to stays on the screen and the keyboard completely stops working. A logout of required.
Running 10.6.2 with all updates applied.

I have a lot of usb stuff strung out: 6 kbds, 5 mice (three kinds), 4 audio interfaces, 7 hubs not counting in kbds, etc.; most powered. At the root of the USB tree is a KVM switch feeding a new MacBook (10.5.2) and a G5-Quad (10.4.11) This all pretty much works fine and runs for weeks without hiccup.
But tonight, one MacPro kbd, quit. It's at the end of the chain, but it has been working fine. Plugged into hub one level up it's fine. A new Apple thin-flat kbd plugged in where it was works fine.
When MacPro kbd plugged in, the light on the hub port flashes. Other stuff (Wacom tablet, Insignia speakers) works fine and lights the lights. With other stuff pulled (use less power?) kbd fails the same.
So what's up with this sort of problem, and how does one trace/debug? Usually, when (once in a while) there's a USB problem, just unplug and plug back in and it works again.

Skype stops working after 20 minutes - the other person can hear me fine, but I cant understand a word the other person is saying (very digitalized). This doesn't happen on the PC so I'm wondering if it's an issue with the MAC. Does anyone have the same problem? Any ideas how to solve it?

I have to delete .plist files..and it usually starts working right away. (com.apple.systempreferences.plist and com.apple.preference.desktopscreeneffect.plist) I've tried resetting the PRAM, etc. The problem gets fixed, only to return about a week later. My screen saver is always set to turn on after 3 minutes.

I have had inquisitor installed and working for months with no problems. For no apparent reason it has stopped working properly. In that it only shows one link "local" and when clicking on this nothing happens. I had downloaded release 58 and Safari is 3.2.1.

I have a macbook that is about 2 years old, maybe a little less, and recently it's been giving me trouble. Every time I go online (on firefox or safari), the internet stops working after about 20 minutes. It used to be about every hour but it's more frequent now. To fix it I have to restart. Once I restarted and the internet didn't even work. It's getting to be immensely frustrating since I have to save everything else I'm working on, restart, and then reopen everything. I don't know much about computers but I'm using a wireless that's shared with one other mac and one other pc in the house. Any ideas of what I should do?

I have two shares that are always connected on my mac (two folders via smb share). They are NAS devices. They are also connected on numerous other macs in the house. On my mac pro, once in a while, I will click in the share and nothing happens. I will disconnect the share and then try to reconnect, and I just get "Connecting to server" forever (until I cancel). A reboot does the trick, but a reboot is a pain because I have two VM sessions, numerous jobs in queue, etc.
Is there a way to restart that daemon that handles smb mac shares? I already tried to stop and start network services.

After chatting on FaceTime on my MacBook pro for approximately 5-7 minutes, the other person cannot hear me. I went to Apple and they said it may be the actually mic/camera connection and would have to replace it. I can't lose a week without my MacBook!

I have a Dell Inspiron 1545, and Safari has been working perfectly up until this last week when I went away. I left my laptop at home with safari running, and I left the laptop on while I was gone. When I got home and clicked on Safari (the laptop had died, which closed all of my programs), the window pops up but then it freeezes and stops responding. When I click on the window, a smaller window pops up asking me if I would like to close the program or wait for it to respond, and when I select close program, another window pops up saying that the WebKit2WebProcess.exe has stopped working. I have tried starting the computer in safe mode and nothing is working. If I reinstall Safari, I run the risk of losing all of my bookmarks. What should I do?!
Info:
Safari, Windows Vista

I noticed my sound wasn't working, so I did a restart. The "blip" sound when you adjust the volume using F11/F12 would play, but as soon as I tried to run something else (YouTube video, iTunes, etc.), that wouldn't play (just get stuck at whatever point I tried to start it). After that, the blip sound no longer worked either.
I have tried the following things already and none of them fixed the problem (all of them reset the "blip" sound, but it always went away again as soon as I tried to play anything):- running Apple Diagnostics (no problem detected)- resetting PRAM- resetting SMC
I've checked things as suggested in other message boards … there's no red light in my headphone jack, nor is the sound muted under System Preferences. The problem persists whether headphones are in or not.

10.9.4 mavericks macbook pro retina to TV via HDMI using an HDMI cable to watch movies on my laptop macbook pro retina. was working this morning, and watched a movie. then I go to work, and come back and now the exact setup is no longer working. it does not show any display in the preferences menus, and the TV is just blue without any input. cable is secure, nothing has changed. nothing.
edit: actually I did pull the HDMI cable out while the two were connected this morning.
tried restarting, reconnecting, nothing ... Why computers suddenly stop working for no reason whatsoever. maybe someone hacked my computer this afternoon while I was gone? it's just a random failure.

I have an obscure brand USB keyboard that I am trying to use with my Mac Mini, with one problem: after the Mini goes to sleep and wakes up again, the keyboard doesn't work. The solution is to either unplug and replug the keyboard or restart, but both are I think unnecessary hassles.
What I like even more is that the keyboard will wake the Mini (by pressing the spacebar or something), but won't work after that.
I also tried a plain ol' Apple keyboard, which works just fine after sleeping/waking.
Any ideas on what's going wrong, or how to fix it without replugging/restarting? It's just a keyboard, so I don't see why it should pose as any real problem after waking, so buying a new keyboard is not quite what I am looking for. I may end up doing it anyways (a wireless one to go with the wireless MX1000 I am using) but at the moment I don't want to spend money for a new keyboard.
It's a 1.66GHz Core Duo, 512MB RAM, 60GB HD, OS X 10.4.10.

So I've been having problems with my TC for awhile but it has gotten much worse. Now I find that I lose my wired and wireless network often. If I go to where TC is I notice that it is very hot. I unplug it and if I leave it unplugged for a while and replug it in I can get back TC. Usually if I replug it in right away it will come back but I lose it a minute later. The length of time it is unplugged for corresponds to how long it will stay active.
I'm assuming the problem is the heat b/c of the hard drive spinning. However this seems strange that this would be a problem as I'm sure Apple would realize that these drives will get hot and there aren't a ton of problems like this. Do you think I should have it replaced? Any ideas that I should try first? If I replace the TC with an old Linksys router I don't have any problems with it, it is just much slower since it is G not N.

I'm on an older blackbook (2 years old? ca. summer 2007) running Leopard and I'm getting some weird behavior with Finder. When I right click on anything in the dock, i.e., to close a program, the dock locks up, I can't click on any of the menu options, Expose stops working and the alt+tab interface stops working, as if everything is frozen... This caused me to think that Finder was crashing, but then I discovered that when I went up to the menubar at the top, everything "unfroze." The dock went back to normal and was usable, expose works fine and the alt-tab interface works fine too.
