In OS X 10.9, you can simply do pmset displaysleepnow. This will immediately turn off your display without changing any of your settings or putting the entire host to sleep.
Escalated privileges don't seem to be required (at least with recent versions of OS X), but if you get a message about inadequate privileges, you could do sudo pmset displaysleepnow.
I haven't tested it myself, but according to John Siracusa's review at ars, if you disable the "Displays have separate Spaces" checkbox in the Mission Control preference pane, the old behavior (including ability to split a window between displays) returns.
You can turn off your iMac (and your macbook) screen without sleeping via the following keyboard shortcut:
⌃ + ⇧ + ⏏
(Control +SHIFT + EJECT)
Machines like the Air and newer MacBook Pro with no optical drives have the power button in the same place as the eject key and it works similarly for display sleeping shortcuts.
I assume you're not using a trackpad, and/or your Show scroll bars preference in System Preferences > General is set to either Automatically based on input device or Always (otherwise, you shouldn't be seeing persistent scrollbars).
Try changing this setting for Terminal only:
defaults write com.apple.Terminal AppleShowScrollBars -string WhenScrolling
Control+Shift+Power For current Mac keyboard layouts. Control+Shift+Eject works for older keyboard layouts that still include the Eject key.
This page explains some alternate solutions as well.
Also, if you have "Require password after sleep or screen saver begins" set to immediately in System Preferences -> Security & Privacy, it will ask you for your ...
While I haven't been able to find a command that will sleep the display natively, there is an app you download that will do it. There are two options from here.
Install the app to the Applications folder and from Terminal or SSH run open /Applications/Sleep\ Display.app
Right click on the app from the Downloads folder and click "Show Package Contents". ...
It seems like the issue is that when I plug the external screen, it messes with the coordinate system of my Mac's screen, effectively shifting the origin of my screen by the resolution of the external screen.
In other words, from the point of view of XQuartz the origin of my Mac's screen changes from 0,0 to 2560,1440 (which is the resolution of my external ...
You can install this command line tool from github.com/nriley/brightness. The install is pretty easy if you have homebrew:
brew install brightness
And usage is straightforward:
Set 100% brightness: brightness 1
Set 50% brightness:
Unfortunately it doesn't work for external monitors. See Does Apple support DDC/CI for 3rd party displays via ...
After some research i found this blog, which perfectly detailed explains how to get this hidden setting:
Open the system preferences
Hold down the command and option keys while clicking the display
Next locate the screen adjustments on the external monitor and you
will notice now there is an option called "Rotation".
Choose 90 Degrees and now your ...
You can do it via an Applescript and run it as such:
tell application "System Events"
key code 107
tell application "System Events"
key code 113
You can save these as .script files and then run them from the CLI like this:
You can also do it this way, but that ...
iPhone X corners do not have a conclusive corner radius. They're not normal arcs, they are ‘continuous corners’.
You can't replicate these with a simple .cornerRadius, and you also can't use Apple's own continuous corners, since that's a private API.
CALayer on iOS 11 has a private "continuousCorners" property, which is what powers many rounded corners ...
Your first stop should be the energy saver preference pane. Dial down the Display sleep slider as short as you can stand it.
If you don't want to wait for this time out, you could also set a hot corner and black screensaver so you could use VNC to set the mouse pointer to the corner to engage a black screensaver so the screen is as dim as possible until the ...
In the release of OS X El Capitan, just shake the cursor to locate it.
Call out your cursor.
Lost your cursor on your crowded desktop? Just shake your finger back and forth on the trackpad or give your mouse a shake, and the cursor gets bigger so it’s easy to spot.
To enable/disable this feature, go to System Preferences > Accessibility ...
If you are still looking for an alternative way, have a look at Spectacle.
You can select from the menu or use a keyboard shortcut.
There are many resize options but your requirement is "Fullscreen ⌥⌘F"
It is not like OS X full screen but Windows like maximum.
For this answer, let's define that…
…the sharpness of a display is the ability to distinguish two distinct pixels.
There is no industry standard for retina display, therefore I'll follow Apple's use of the word. The term retina display is relative, as the definition follows the human eyes's perception of a display's sharpness:
As implemented on iOS 9 and later, OS X 10.11 lets you split the unified full-screen view into two portrait sections with one application on the left side of the partition and a different one on the right.
It's pretty basic, but it also is elegantly minimal with a clear geometry with only one degree of freedom.
My hope is that as more people get used to ...
If you are very lucky it is just dirt and can be wiped off but usually it is permanent and there isn't much way to avoid them. I have seen it happen even when a soft cloth is used to cover the keys when the lid is closed. In fact that may even make it worse as the cloth adds thickness to the sandwich and may make the contact between the high points of the ...
The graphics are telling you to turn on the Magic Mouse or Magic Trackpad associated with the MacBook. Have you ever connected one of these devices to it?
If you haven't, I have to wonder if the internal keyboard and trackpad are not connected somehow. What year is this MacBook? Is it still under warranty?
Unless you can boot to recovery and reinstall OS ...
I've created a node module for this that supports setting the brightness using the CLI. See https://github.com/kevva/brightness-cli.
npm install --global brightness-cli
And then simply just run brightness from your command line.
Yes, glass chip kits can be used to fix a cracked screen, but only in the following conditions:
The crack does not cover any of the touch surface (only the bezel area is cracked). Anywhere resin is left on the surface of the device or seeps under the glass can block the electrical signal from your finger and prevent the device from reading a touch in that ...

Command + F2 to detect displays

I've once got water in a Dell (work)laptop and it started to get lighter and lighter the further water got. This is because the screen is built with multiple layers and you got water between them.
I would definately recommend you to shut down the device and put it in rice.
It depends on the cause of the yellowing.
I personally have seen the following situations:
Psycological yellow where any time you have a black border and a white area, the brain will color the white yellow. If you hide the black with a piece of white paper, the yellowness magically disappears.
Permanent manufacturing problem where the LCD is pinched ...
I have an iPhone 4S. Like you, I originally thought that I ought to get a protective case for my iPhone. I tried several cases, but none of them were satisfactory (too bulky, too cumbersome to open to get to the phone, too ugly).
I now have no case for the phone, and I keep it in my trouser pocket all the time. Instead of getting a case for the phone, ...
