OS X :: Command, Control, Alt 8 Turns Screen Negative / Stop Working?
Jul 27, 2009
I saw this little "trick" command, control, alt, 8 in a Mac article a few weeks ago. It was nothing more than a cool, little screen alteration that makes the screen go negative. I tried it after first getting my Mac. Just this past week, I tried to do it again and it is not working. Not that it is a serious issue however it is more of a curiousity why it stopped. Did some application I installed on my machine cause this feature to halt? Just curious if anyone has the answer. I tried disabling Shades, Growl and even turned off my power settings to see if that was interfering.
I recently have been running into problems with my Macbook Pro in that an hour or two after startup, the hot corners no longer work and command tab no longer works. That is when I try to use them nothing happens at all. The keyboard still functions normally other than that. Also, if I then try to shutdown the system appears to begin the shutdown in that my desktop icons disappear, but then the machine just sits there and will never shutdown. I am then forced to hold the power key down to force a hard shutdown. Then once I do a startup, I have my hot corners back and command tab works. Until it sits for a while and then I start the cycle over.
I cannot control my screen brightness using the F5 and F8 keys. The only way I can adjust it is through System Preferences. I tried just F5 fn F5, Control F5, Option F5 and Command F5 and non work.
Is it possible to switch the control key to the command key in Windows? I am so used the to CMD shortcuts, and hate having to move my finger to CTRLI downloaded a program to edit the registry, but it didn't change the command key, just the control key. So I had two keys that were assigned to the left command button. I cannot remember the name of the program for the life of me.
I just bought a Macbook Pro 15" i7; the only problem I've had with it is this: every now and then my Expose/Space/Screen Corners stop working, and the only solution I can find is to just restart my computer (which thanks to the i7 is only about 20 seconds anyway ). Does anyone here have any advice on this?
OX 10.4.11. Screen freezes when I stop working on computer. Usually can happen anywhere from 5 minutes to hours after I leave and come back. It doesnt happen when I'm working on computer and it doesnt seem to matter what programs I leave open. Ive tried zapping the pram...disabling the screensaver..I did an archive and install of the operating sysem (actually surprized myself by doing that one ) Ive run a disk utility and hardware check.. My computer is running a lot faster now, but it still has frozen up and needs to be restarted by holding down the button for a few seconds.
When we upgraded to 10.5 and got the new iMac (I don't know which one caused the problem) I noticed that the Command, control, alt, and shift button all act like caps lock. I use those buttons all the time, and if I accidentally press one and have no idea what it is, I am stuck trying to figure out what to do.
Every time I press Command it opens Mission Control. Would loike to reset so I can press command W or other similar combinations to get back to normal.
It seems that in his nasty habit of taking naps while resting a body part on the keyboard, he has managed to press some obscure key combination that has inverted the colors on my screen (like a color photograph negative). I've searched everywhere to try to revert this, but had no luck so far. When I restart, and/or log out and back in again, the screen is normal during the booting sequence till I choose the account I want to log in with, then it immediatly goes into "x-ray" mode. If I choose another account, it will boot and log in with no screen problem whatsoever. So this must be either a preference option has been changed via keyboard command or the account is corrupted. Right?
it makes everything on the screen a negative. I like to use it for design ideas, and screenshots sometimes. Hit Ctrl+Option+Command+8 and see the madness.
My screen suddenly went xray/negative/black & white. Everything on the internet says to hit "control+option+command+8," but that doesn't fix it--the screen just goes white. Going to system preference and adjusting the universal access items doesn't help either.
suddenly my screen color changed to negative/black on white. but when i inverted the screen did not back to normal quality. the trace or shadows remains when i move the window. when i log out it turns again to negative form. and when i log in it seems back to normal. but it does not have the same quality and sharpness.
i am currently on my imac 5.1 intel core 2 duo 2.16ghz. my 2 year old son managed to change my screen into negative color this includes everything from start up picture to screensaver to photo booth to skype etc etc etc. i have tried everything to get my screen back to normal and can't do it hoping you have any idea on how to fix this
My room mate turns on his computer and the screen is fine. After about 15 miuntes the screen image basically goes negative for a minute or so. After that little pixels begin to rain down until the entire screen is pixelated. When it is pixelated I can use an external monitor to view my desktop perfectly, which eliminates the graphics card as the issue in my opinion.
There is a possibility that there is something amiss with my external hard drive. I have ejected the hard drive and read in a thread that there is a way to disable TM's continuous "local Snapshots" Backup with a command typed in Terminal. The reasoning is that TM uses a lot of CPU's? and things can become a bit sluggish. If I turn TM to "OFF", doesn't this stop the hourly snapshots on the INTERNAL hard drive?
My MBP has this issue every once in a while where I have to hold the power button and force shut down. Randomly the volume keys/brightness etc. stop working and i can't open apps or shut it down normally. Everything still works though (can still function in open applications) Anyone know what the problem is? It fixes when I force reset.
I had an image from an older macbook (10.5.4) and I put it in a newer MacBook which I assume was could not boot as far back as 10.5.4, so I updated it by booting 10.5.6 on an external and running the combo 10.5.7 update on the MacBook's internal drive. I boot and after staying on a blue screen for a while, it goes black and shows me a command prompt and I can see all the processes starting up. then it goes back to blue and works normally. On shutdown, I see the prompt again. I cannot boot into safe mode or single user mode for some reason. When holding down the s and shift it still does the same thing. I can however still use option to boot from a different drive.
The computer runs perfectly normally once booted. I just don't want to see the command line stuff. So is there some way to stop it, or hide it?
I just bought a new keyboard for my mac, and although it is very sleek (but the keys are smaller), I have a problem. I cannot configure Control-F11 as an application shortcut. It will only decrease the volume when I try to set it as that. Is there a way to do this? (*Better be )
I have done this before where I disabled infrared control on the MacBook Pro but for the life of me I cant find the spot where to disable it on the MacBook.
Does anyone know if it's possible, and if so how, to stop my iMac from registering when I use my little white Apple remote (the one that comes with iMac, AppleTV etc)? Reason being when I go to run through my AppleTV menu my iMac registers each press as well.
I have the Remote app for my iPhone and iPad but I'd rather be able to use the Apple remote aswell for quick pauses etc., so as to not have to load the app just to pause, skip etc., if I'm using my iPhone/iPad for something else at the time.
How can I stop the control button from moving the open applications up and exposing the desktop? It is getting very annoying when I want to use the control button for other functions. I tried looking in settings under keyboard, but found nothing.
So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.
Since a couple of days, my screen (iMac 27" mid 2011) turns off. Also, half of the screen looks darker. Is it a hardware problem or maybe can be solved by software?
For a while now the command-tab, dashboard key and spaces key do not work. I press the key and nothing happens. If I restart the OS (OS X 10.5.5) they work but only for a short time and stop working again. Other accounts on the system work fine and do not have this problem.
