    Are the colours there right from the start of the machine, meaning when you turn it on, as soon as the display comes on are the negative colors there, or do they appear after the software loads in?

I'm not sure what exactly would cause Universal Access to be unresponsive, but I have some troubleshooting ideas:

Try putting the file in the trash.

It is in ~/Library/Preferences

1. Click on Finder (the smiling guy on the Dock).
2. Press and hold the following keys: Command and Shift and H (Command-Shift-H). That will take you to your home folder.
3. Double-click the mouse on the Preferences folder in the window that pops up.
4. Find
5. Click and hold down the mouse button on that file and drag it to the trash.
6. Click and hold on the trash icon. Select "Empty Trash".
7. Click System Preferences from the Apple menu or the Dock. Click Universal Access. Click "Black on white" under the Seeing tab.

Please let us know if that works. Another possible solution, though a bit drastic, would be to reinstall your operating system. If the above solution doesn't work, I can explain how to do that, if necessary. I'll also be thinking about other possible fixes.

Good luck!

Black and white or negative screen resolution in Mac OS X

A black and white display, or negative screen resolution, is an issue which can occur within the various Mac OS X system versions ranging from Mac OS X 10.3 to Mac OS X 10.6.

It can appear as an anomaly which can leave a Mac User dumbfounded, not sure what is going on.

At one time your screen is normal like this, but then somehow,


the screen changes into this strange negative, inverted screen.


So how does this occur?

The answer is more simple than you think.

An inverted screen like the one you see in the screen shot above, is not actually an anomaly, or the result of some sudden strange happenstance. What's more, chances are, this occurred because of what you did.

Its an easy fix however, because the only way your Mac OS X desktop screen can turn into a negative or black and white resolution, from its normal color resolution, is if a setting within your Mac OS X system has been modified.

To return your screen back to the normal color resolution, follow these steps:

* Click on the Apple menu icon, located on the upper left corner of your Mac OS X desktop screen.

* From the drop down menu, select System Preferences.

* Within System Preferences, select the pane (in System Preferences, Apple references all icons as "panes") entitled "Universal Access".

Quick Note About Universal Access:
The reason this System Preferences pane is known as"Universal Access", is due to the purposes Apple designed it for. If you notice the image for this pane above, this symbol for this feature, is similar to a placard or sign you would see on a car license plate, parking space, door or building, for an individual who has a disability or is handicapped.

Universal Access was designed to enhance features like Voice-over speech (your Mac talks to you), screen size, display settings, keyboard and mouse settings for those Mac users who are vision impaired, hearing impaired and /or physically disabled.

* For the next steps in the process:

Click on the Universal Access pane.
If you look in the screen shot, under Display, you will see that the current setting is "White on Black".


Click on the radio button entitled "Black on White"
and this is the window you will see:


Back to normal!


That is all it takes, to return your desktop screen resolution back to normal.

This is why you were suggested as the probable cause" for your desktop screen to go into Inverted mode. Chances are you may have been in System Preferences, clicked on the Universal Access pane, and in exploring settings, may have clicked the Display setting and the
White on Black radio button, causing the screen to go into
the inverted mode or change in gray scale.

Another theory could be that you may have accidentally pressed the Ctrl-Alt-Apple Command keys on your keyboard, combined with either < > keys, depending on if you were in process of' increasing or decreasing contrast on your Mac's screen or display.

The true purpose of the inverted screen mode or change in gray scale, is to aid Mac Users who may be sensitive to the bright normal colors, that you and I see on the standard Mac OS X display screen, due to poor or failing vision.

So now that your screen is back to normal, if you should see an inverted display, or screen that resembles a negative resolution, like that of a photo negative, you know how to correct this issue.

Make reading documents easier on the eyes

Hold down ctrl, alt/option and command keys and press 8. You will invert the display and make reading documents much easier - especially in a dark room. Press again to return to normal.

My mac screen is in negative and it still doesnt change when i press control option command 8 (it just makes the screen lighter). the colors are off unless i press the dashboard button but its annoying...

Unfortunately with any kind of liquid damage all bets are off. You can change one thing and it may or may not fix the issue. And after some time you might have a completely different issue. You're smart thing is to cut your losses and get a new computer. Remember to backup your system before you lose everything. To be quite honest I'm surprised still working. Good luck.

I somehow screwed up the size of the image on my ibook. How can I restore it to the full screen?

Thanks for contacting Fixya Support.

You may have a System Preferences setting that needs to be activated.

Try this:

Click on Apple menu icon in upper left corner of your screen and select System Preferences.

* Click on Universal Access pane, within the System Preferences window..

* Within Universal Access, under Zoom settings,
make sure the Zoom setting is set to "Off"

This should bring your screen back to normal.

If you need more assistance, just let me know.

Negative screen image

Look in System Preferences for Universal Access, there is a Display option which says Black on White(the normal setting) and White on Black (the setting that has been enabled).

There is a keyboard short cut to change the setting, it involves pressing four keys - Apple, Option, ^ and 8.

My desktop looks like negative photo shot?

Aldanipio2 is close. You go to...
  1. System Preferences
  2. Click Universal Access
  3. Click Black on White (Yours is probably set to White on Black)
You many have gotten into this mode to begin with by pressing
Try that key combination and you will see it toggles you between positive and negative image. This can often trigger itself accidentally when the key command is similar to that in another program. I often find whenever anything visibly strange happens to my desktop, Universal Access is the first place to look.
Best of Luck.

Imac is displaying in negative.i.e word documents are black with white text. Photos have cyan faces instead of red. Mac is working apart from color issues.

It sounds like you managed to turn on the Universal Access inverse image setting.  Try hitting ctrl-option-cmd-8.
For future reference, go to the Universal Access pref pane under System preferences.  
I hope that helps.
