OS X :: Shutting Off IMac Screen (Keyboard Command)
Mar 29, 2009
I use "Ctrl+Shift+Eject" to shut off my iMac screen (not shutdown) usually before I go to sleep, but recently, I've had to hit it 5 or 6 times before it actually turns off the screen. It also happens when putting the computer to sleep pressing "Option+Command+Eject".

Is there a keyboard command that will take me to the top of the next page in Word 2011 on a MacBook Air? I can creep up and down the existing page using Fn + right/left arrows. I can go to the top and bottom of the file using Fn + Command + left/right arrows. I want to go to the TOP of the next page (Page Down) and googling isn't turning up anything that works.
Info:
MacBook Air, OS X Mavericks (10.9.4)

Does anyone know the terminal command for toggling on/off the System Prefs for Keyboard & Mouse? I'd use it for an Automator workflow or Quickeys shortcut. The specific setting is "Use all F1, F2, etc keys as standard function keys." I and many other Cinema 4D users find ourselves needing to turn this on and off all day long, because the app uses that F8 key that the new Aluminum keyboards have coopted, but using it means losing our speaker volume / mute settings. This is in Tiger btw.

Is anybody know if there is a way to switch to a particular "input source" (keyboard) with a command line? (or with Apple Script).
Not switch to the next or the previous, but to a specific one. Like switch to "Canadian French" or "Us English".

For no apparent reason the command-space keyboard shortcut no longer works for opening Spotlight. I go into the preferences for Spotlight and it shows no keyboard shortcut, I make it command-space again, exit, and it still doesn't work. If I go back into the preferences, it is blank again. What is going on?

How can I disable the (Command + "Left or Right Arrow") Keystroke in Safari that navigates Back and Forward. If I could also disable the (delete) key from navigating back, I would be happy.Â
I edit text with these keystrokes all the time and now that I've upgraded to Lion and Safari 5.1.5 I run into problems with my workflow.Â
I just want (delete) to delete text and (Command + Arrow Key) to select a whole line of text.

My screen went green before shutting down... Is this common? It didn't warn me that I had a low battery. We I restarted it I got a screen saying ' The date on my computer was set to before 1/1/2008 and it would cause problems. I checked the time & date and it's got the correct time. it anyone has experienced this I would like to know.

Is there any way to set my macbook pro to shut off rather than going to sleep? My problem stems around my family not shutting off the computer after they are done using it. They will simply shut the lid, putting it to sleep. Normally, this isn't a problem, but the computer then may go unused for days which then leaves the battery depleted. I cannot get them to shut off the computer, I could set the computer to shut off when the lid is closed rather than go to sleep.Â

So frustrated with this situation. It appears this is only happening since upgrading to Lion so that's why I've chose to post it in this forum. My screen has been shutting off randomly. And I've only been able to get it to happen when I use gestures on the trackpad. (I.E.: "App Expose, "Show desktop" or "Show all windows.) I say my screen because the HD is still spinning, the keyboard backlights are still on and the status light is still lit. I can't do anything but hard shutdown. I've tried adjusting the brightness, clicking, keyboard commands (force quit) and nothing does anything. I've been sending the crash report to Apple but I feel like that is pointless so I'm turning to the forum for a possible answer. I've inluded my specs below as well as a copy of the log that got sent to apple (in blue). I don't know if it will say anything to anyone but it's worth a shot. I don't think it's a screen cable issue cause I'm not moving or adjusting the screen when this is happening.

My 4 year old Powerbook Pro locks up intermittenly when shutting down. Could this have something to do with Malware or adding an antiVirus program? Using 10.6 OS.

I Have a very new Mac, and for some reason, the screen goes black when I open it more than halfway. It happens to all the users, and even if it is or isn't charging. The brightening keys also doesn't do anything for it. I don't know if this is connected, but I also have half of the lights on at the dock, it kind of looks like lights on a stage..

Recently a email link was clicked on and since then my wife has been having issues with her G5 shutting down. Sometimes the box will not completely boot at all and others it will boot up for a moment and then shut itself off.
I have looked for teh Flashback Trojan and appear to be clean. If i boot the box in safe mode when booted in safe mode all seems okay. I have also recently reset the PRAM and have had the machine up for a few minutes and it has not shut down yet.

I have a iMac G5 (Pre-iSight). I just got home and my computer was off, I didn't turn it off and I asked my mom, she said she didn't come into my room. I was posting something on here and my computer shut off on its own. What gives?

I have a refurbished iMac G5 that randomly just shuts off. It makes a little "zzzttt" sound, like something is short circuiting and then dies. Sometimes I can power it right back on and sometimes I have to unplug it and wait a few hours before it will come back on. While it's running, there are no issues. It functions beautifully. Anyone else had this type of problem or can you suggest a solution? Here's the info on it:
Mac OSX 10.4.1,
Machine Name:iMac G5
Machine Model:PowerMac8,1
CPU Type:PowerPC G5 (3.0)
Number Of CPUs:1
CPU Speed:1.8 GHz
L2 Cache (per CPU):512 KB

I've learned quite a bit from this site in recent weeks as I found it following my purchase of a 20" iMac (2.66 GHz) a month ago. I've got a question for the group and I'm quite certain it's a stupid one so please be gentle. As I do every night, last night I put my iMac to sleep at around 11:15 pm before going to bed. Upon awaking this morning I couldn't get it to wake up. Hitting keys on the keyboard didn't do it, nor did moving the mouse around. I'm not sure if this is important but both my keyboard and mouse are wireless. Power to the other things on my desk was still on so it wasn't a power problem.
Anyway, I hit the power button on the back to see if it had simply shut itself off and nothing happened. I hit it again. still nothing. Finally, hitting it a third time did the trick and the computer roared to life and came on normally. It had never done this before. It had always immediately awakened in the morning upon hitting a button on the keyboard. First, is this common for an iMac to shut itself down? Second, why would the power button be unresponsive? Finally, if the machine had actually not been off (which I doubt very seriously) did I do a big "no no" by hitting the power button to turn it off/on?

I have a ibook G4 that's been randomly shutting down. It started doing this maybe about a month ago but it's started getting really bad lately. At first it would shut down if I unplugged the adapter. Not every time I unplugged it, but probably about 50% of the time. When I press the battery button all of the green lights would light up. About half of the time it will start up again if I just hit the power button but the half of the time I have to reset the pRAM. Lately this same thing has been happening except when the computer is still plugged in. And when in say shutting down I mean essentially instantaneously. One second it's on and then the screen goes black and it makes that turning off noise. Not a chime, but like all the fans and hardware are coming to a stop.

I have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something
Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.

I don't know if it is a fan or a drive that starts up and runs really fast and loud, then the computer shuts off. I always thought it was the fan, but now am not sure. I have moved it to a place where it is exposed to more air, but that has not seemed to help. Does anyone have an idea or solution to this problem? The nearest Mac dealer is about 80 miles away, so if I can fix this on my own, I would like to try.

I have a late-2009 27" iMac i7 with 8gb Ram and a 1TB HD. I updated my OS to Yosemite soon after it came out. Now, I admit I don't use the computer that often, so it took a while to notice the issues but, we first realized there was a problem in early November when my husband could not download a game (presumably because of the wi-if connectivity issues supposedly fixed in the latest update). It was around a week after he finally was able to download tthe game, that he was playing it and the computer would just shut down out of nowhere. No warning, just shut down and restart with the "your computer shut down unexpectedly" screen.
Now, because it happened so many times, I started to get worried about all of my photos and music that is stored on thIs computer, so I went to do a back-up on my time capsule. This was when I noticed my computer had at some point been renamed (not by any human) to "my Computer (3)" when prior to yosemite (as far as I can tell) it was named "my computer". Also at this point I could not for the life of me get the time capsule to back up the computer as it was looking for "my computer" and all that was available was "my computer (3)". This is when it had been working flawlessly for years. I ultimately had to wipe the TC completely, reformat it and start a back up from scratch. It was for the short period of time that the time capsule was not connected to the computer that we noticed it was no longer shutting down unexpectedly. however, one the TC was reconnected and doing a back up, anything extra that you would be doing (with the exception of web surfing) caused the computer to crash.
So, simple fix, right? Turn off the auto back ups while and try to remember to turn them on every so often. fine , dandy, whatever. However, I have done the latest yosemite update and the wi-if still does not seem to be staying connected, disconnecting every few minutes. Now I'm seemingly having more issues with a game that is well within the limits for my computer and the game will not start.

I don't know if this has been discussed here but all of a sudden my iMac, running Snow Leopard, 10.6.1) keeps waking up all on it's own. I believe this started after the latest update of Java and Super drive firmware (I believe these were the latest updates).
Is there anything I can do short of shutting the computer down.

I can't figure this out. My iMackeeps shutting itself down part way through the Windows 7 Boot Camp install. I can't get it completed. Usually about at the point were files are copied it turns off.
Is it possible the fans are not working properly while booted to a CD causing it to overheat and shut down?

My friends iMac G5 just recently has been randomly shutting down. Does anyone know anything I can do to him fix his computer?
I checked [URL] and there seems to be issues with power on some models, but his serial number just misses the infected batch.

I looked into my issue a little but recently my IMac G5 started randomly shutting down when left unused for a bit but that seems to have stopped as far as I have noted. Now occasionally when it goes into sleep mode it will freeze on the black screen and the fan will go crazy. I plan on buying a MBP, if the update ever comes out, and then ill just completely wipe the IMac and give it to my parents, who still use the original I mac, G3 or something. I read a certain series of I Macs were having motherboard problems, W950 or something, but mine wasn't that serial code.
