So you are trying to wake your Mac from sleep, and it just wouldn’t. All you see is a black screen on your MacBook Pro, no matter what keys you are pressing. Below you’ll find a couple of solutions (mostly based on users’ cases) to bring your Mac back to the light.
The NOV Grid for MonoMac & Xamarin.Mac is a high performance Data Grid component for displaying and editing tabular data within your Mac OS applications. NOV Grid for for MonoMac & Xamarin.Mac is built upon the NOV Document Object Model (DOM) and is a scalable and extensible solution. An Internet blackout or outage can be caused by local signalling interruptions. Disruptions of submarine communications cables may cause blackouts or slowdowns to large areas, such as in the 2008 submarine cable disruption. Less-developed countries are more vulnerable due to a small number of high-capacity links. Marc Elsberg is a former creative director in advertising. His debut thriller BLACKOUT is a frighteningly plausible drama of an international blackout caused by a hacker attack. An instant bestseller in Germany, it has sold over a million copies and has been translated worldwide. Marc Elsberg lives in Vienna, Austria. Blackout Grid currently has 50 levels, each which record a best score (or lowest number of moves). Blackout Grid also features a random level generator for unlimited replay value! Race the clock in random mode to try and clear as many boards as possible!
Reasons your Mac screen goes black:
- 3rd party apps that expand the screen
- Recently upgraded operating system
- Corrupted display and energy settings
- Cables not connected
Easy fixes for MacBook black screen
1. Adjust your display’s brightness
You may have accidentally pressed the brightness keys on the keyboard, so your screen dimmed down. Could it be your cat stepping on keys? Use F1 and F2 buttons to light the black screen on your Mac.
2. Check if the power is on
Examine your charger cable is intact and if your Mac is charging. Is the green light on? To rule out the power issues, check if your Mac produces any noise — from the hard drive or fans. If you still see the black screen on Mac, read on.
3. Disconnect all peripherals
Remove all external devices like printers or external drives. These devices may start their own dialogues, which could interfere with your display settings.
More solutions if your MacBook Pro won’t turn on
Force restart your Mac
In most cases forcing your Mac to restart helps to fix it if your Mac won’t boot. The variance of this issue is your Mac not waking up after sleep. Try to open and close the MacBook lid and press a few keys on a keyboard. It might help, but if it doesn’t, in no way should you panic — first, let’s perform a quick force restart.
- Hold down the Power key for about 6 seconds.
- Wait for your Mac to shut down and press the Power key again.
Reset your Mac’s NVRAM settings
NVRAM stands for non-volatile RAM and is basically a functionality that stores in-memory settings for display, speakers, primary startup disk, etc. Everything remotely connected with the boot process (like your MacBook won’t turn on) can be set back to factory settings during the NVRAM reset.
To flush NVRAM settings:
- Shut your Mac down.
- Press the Power key.
- Wait for your Mac to start loading.
- When you hear a startup sound, hold down Cmd + Option + P + R.
- Keep pressing the keys until you hear a second startup sound
Do basic Mac maintenance: disk permissions and Login Items
Did resetting NVRAM do the trick? Now that your display is back to the light, you should be able to do a bit of maintenance under the hood of your Mac. In many reported cases, removing old cache files and broken login items helped prevent the “black screen” problem. Oftentimes, the reason for your Macbook black screen problem is broken disk permissions not allowing your Mac to boot normally. A good solution is to use the app called CleanMyMac on your machine and run the Repair Disk Permissions command.
- Download the app (it’s free to download).
- Install it and go to the Maintenance module.
- Tick Repair Disk Permissions and click Run.
From my experience, it’s the easiest way to optimize hardly-accessible parts of your Mac.
Another possible culprit — the corrupted Login Items. The truth is, some apps like antivirus software would inadvertently sneak into the list of your startup programs; if something goes wrong with the app, it will then affect your Mac’s booting. So, it makes sense that you check your Login Items list and uninstall the unwanted app — both too can be done with CleanMyMac’s free version.
Zap your Mac’s SMC settings
SMC is a System Management Controller. What it controls is temperature, lights, keyboard, fans, and many other side-processes. According to Mac support forums, resetting SMC helps in 90% of the cases when your Mac’s screen goes black. To perform this trick, follow the tips below.
For a MacBook with a non-removable battery:
- Shut your Mac down.
- Connect your Mac to a power outlet.
- While your Mac is still shut, Press the Shift + Option + Control and Power key simultaneously.
- Let go of the keys and boot your Mac again.
For a Desktop Mac: iMac, iMac Pro:
- Unplug the power cable.
- Wait for about 15 seconds.
- Plug your Mac back in and leave it for about 5 seconds.
- Start your Mac in a normal fashion.
Enter your password — a surprising trick that works
Though it looks counter-intuitive, you may try this solution when your Mac screen goes black. Still, with your Mac’s black screen on startup, enter the password — as if you would normally do. Now press the Return key. Lots of users have reported that this option helped to bring their Macs to life.
A variance of this trick has been found on many Mac forums. Once again, it implies that you press the keys on your Mac in a “blind” mode, hoping that it will light up.
- Press the Power key — just once to summon the restart dialogue.
- Press the S key to send your Mac to sleep.
- Press and hold the Power key to perform a forced shut down.
- Wait for about 15 secs and start your Mac as usual.
Check for any magnets nearby
Inside your MacBook's lid, there's a tiny magnet that reacts when the lid is closed. But when there are other magnets nearby that sends a wrong signal to your MacBook telling it to shut down. For example, this happens if you place your computer atop of an audio speaker.
Placing your MacBook next to a magnet may accidentally shut it down, even if the lid is open.
MacBook asking you to reset your password on bootup?
It may happen that your Mac became unresponsive and asks you to reset your password. However, after following all the on-screen instructions and changing your password, nothing happens — you still see the black screen. Don't worry, there is an easy fix.
When the screen is black, shine the light behind the display through Apple. This will help you see the login icon and put the cursor in the correct place. Then just log in, and the screen will come back.
The last-ditch solution to MacBook black screen
Re-install the macOS
The lion’s share of issues we deal with on our computers is software-related. The MacBook display not working is not an exception. So it makes sense that you update all your apps to their latest versions, including the macOS.
Here is the guide on how to quickly re-install the macOS:
If all of the above didn’t work, let go of it and take your Mac over to the service — you’ve done all you could. We hope this article was fun and helpful — feel free to share.
| Operating system | macOS |

| Service name | Dock.app |
| Type | Taskbar |
The Dock is a prominent feature of the graphical user interface of macOS. It is used to launch applications and to switch between running applications. The Dock is also a prominent feature of macOS's predecessor NeXTSTEP and OpenStep operating systems. The earliest known implementations of a dock are found in operating systems such as RISC OS and NeXTSTEP. iOS has its own version of the Dock for the iPhone and iPod Touch, as does iPadOS for the iPad.
Apple applied for a US patent for the design of the Dock in 1999 and was granted the patent in October 2008, nearly a decade later.[1] Any application can be dragged and dropped onto the Dock to add it to the dock, and any application can be dragged from the dock to remove it, except for Finder and Trash, which are permanent fixtures as the leftmost and rightmost items (or highest and lowest items if the Dock is vertically oriented), respectively. Part of the macOS Core Services, Dock.app is located at /System/Library/CoreServices/.
Overview[edit]
In NeXTSTEP and OpenStep, the Dock is an application launcher that holds icons for frequently used programs. The icon for the Workspace Manager and the Recycler are always visible. The Dock indicates if a program is not running by showing an ellipsis below its icon. If the program is running, there isn't an ellipsis on the icon. In macOS, running applications have been variously identified by a small black triangle (Mac OS X 10.0-10.4) a blue-tinted luminous dot (Mac OS X 10.5-10.7), a horizontal light bar (OS X 10.8 and 10.9), and a simple black or white dot (OS X 10.10-present).
In macOS, however, the Dock is used as a repository for any program or file in the operating system. It can hold any number of items and resizes them dynamically to fit while using magnification to better view smaller items. By default, it appears on the bottom edge of the screen, but it can also instead be placed on the left or right edges of the screen if the user wishes. Applications that do not normally keep icons in the Dock will still appear there when running and remain until they are quit. These features are unlike those of the dock in the NeXT operating systems where the capacity of the Dock is dependent on display resolution. This may be an attempt to recover some Shelf functionality since macOS inherits no other such technology from NeXTSTEP. (Minimal Shelf functionality has been implemented in the Finder.)
The changes to the dock bring its functionality also close to that of Apple's Newton OSButton Bar, as found in the MessagePad 2x00 series and the likes. Applications could be dragged in and out of the Extras Drawer, a Finder-like app, onto the bar. Also, when the screen was put into landscape mode, the user could choose to position the Button Bar at the right or left side of the screen, just like the Dock in macOS.
The macOS Dock also has extended menus that control applications without making them visible on screen. On most applications it has simple options such as Quit, Keep In Dock, Remove From Dock, and other options, though some applications use these menus for other purposes, such as iTunes, which uses this menu as a way for a user to control certain playback options. Other Applications include changing the status of an online alias (MSN, AIM/iChat etc.) or automatically saving the changes that have been made in a document (There is no current application with this feature made available for macOS). Docklings (in Mac OS X 10.4 or earlier) can also be opened by using the right-mouse button, if the mouse has one, but most of the time either clicking and holding or control-click will bring the menu up.
Electric Grid Blackout
In Mac OS X Leopard, docklings were replaced by Stacks. Stacks 'stack' files into a small organized folder on the Dock, and they can be opened by left-clicking.Stacks could be shown in three ways: a 'fan', a 'grid', or a 'list', which is similar to docklings. In grid view, the folders in that stack can be opened directly in that stack without the need to open Finder.
Blackout Grid Mac Os Catalina
In iOS, the dock is used to store applications and, since iOS 4, folders containing applications. Unlike the macOS dock, a maximum of 4 icons can be placed in the dock on the iPhone and the iPod Touch. The maximum for the iPad however is 16 icons (13 apps and 3 recently opened apps). The size of the dock on iOS cannot be changed.
When an application on the Dock is launched by clicking on it, it will jump until the software is finished loading. Additionally, when an application requires attention from a user, it will jump even higher until its icon is clicked and the user attends to its demands.
Design[edit]
The original version of the dock, found in Mac OS X Public Beta to 10.0, presents a flat white translucent interface with the Aqua styled pinstripes. The dock found in Mac OS X 10.1 to 10.4 removes the pinstripes, but otherwise is identical. Mac OS X 10.5 to 10.7 presents the applications on a three-dimensional glassy surface from a perspective instead of the traditional flat one, resembling Sun Microsystems' Project Looking Glass application dock.[2] OS X 10.8 to 10.9 changes the look to resemble frosted glass with rounded corners. OS X 10.10 and later revert to a two-dimensional appearance, similar to Mac OS X 10.4, although more translucent and with a iOS 7 blur effect.
In iPhone OS 1 to 3, the dock used a metal look which looks similar to the front of the Power Mac G5 (2003-2005) and Mac Pro(2006-2012 or 2019-). iPhone OS 3.2 for iPad and iOS 4 to 6 adopted the dock design from Mac OS X 10.5 to 10.7 which was used until iOS 7, which uses a similar dock from Mac OS X Tiger but with iOS 7 styled blur effects.[citation needed] In iOS 11, the dock for the iPad and iPhone X is redesigned to more resemble the macOS dock.[3][4]
Related software[edit]
The classic Mac OS does have a dock-like application called Launcher, which was first introduced with Macintosh Performa models in 1993 and later included as part of System 7.5.1. It performs the same basic function.[5] Also, add-ons such as DragThing added a dock for users of earlier versions.
Microsoft implemented a simplified dock feature in Windows 98 with the Quick Launch toolbar and this feature remained until Windows 7, where it was replaced by the Superbar, which implements functionality similar to the macOS Dock.
Various docks are also used in Linux and BSD. Some examples are Window Maker (which emulates the look and feel of the NeXTstep GUI), Docky, and Avant Window Navigator, KXDocker (amongst others) for KDE and various other gdesklet/adesklets docks, AfterStep's Wharf (a derivation from the NeXTstep UI), iTask NG (a module used with some Enlightenment-based Linux distributions such as gOS) and Blackbox's Slit.
Criticism[edit]
Bruce Tognazzini, a usability consultant who worked for Apple in the 1980s and 1990s before Mac OS X was developed, wrote an article in 2001 listing ten problems he saw with the Dock. This article was updated in 2004, removing two of the original criticisms and adding a new one. One of his concerns was that the Dock uses too much screen space. Another was that icons only show their labels when the pointer hovers over them, so similar-looking folders, files, and windows are difficult to distinguish. Tognazzini also criticized the fact that when icons are dragged out of the Dock, they vanish with no easy way to get them back; he called this behavior 'object annihilation'.[6]
John Siracusa, writing for Ars Technica, also pointed out some issues with the Dock around the releases of Mac OS X Public Beta in 2000. He noted that because the Dock is centered, adding and removing icons changes the location of the other icons.[7] In a review of Mac OS X v10.0 the following year, he also noted that the Dock does far too many tasks than it should for optimum ease-of-use, including launching apps, switching apps, opening files, and holding minimized windows.[8] Siracusa further criticized the Dock after the release of Mac OS X v10.5, noting that it was made less usable for the sake of eye-candy. Siracusa criticized the 3D look and reflections, the faint blue indicator for open applications, and less distinguishable files and folders.[9]
Thom Holwerda, a managing editor OSNews, stated some concerns with the Dock, including the facts that it grows in both directions, holds the Trash icon, and has no persistent labels. Holwerda also criticized the revised Dock appearance in Mac OS X v10.5.[10]
