Solving the OS X black screen problem while loading a MacBook
When you boot an OS X system on a Mac, problems may arise that lead to a black screen.
You might think that this is a hardware breakdown and in some cases this will be true, but more often than not, a black screen appears due to software problems that can be solved in a few simple steps.
First, do a SMC reset during MacBook startup.
This is the first thing that comes to the head of an advanced Mac user. Resetting the SMC will allow you to resume the parameters of the system management controller, which will fix problems with cooling, sleep and of course, problems with the display and the black screen.
On any modern MacBook Pro or MacBook Air with a non-removable battery, you can reset the SMC by following the instructions:
- Turn off your Mac and plug it in;
- Hold down the Shift-Control-Option keys (left) and the power button on the keyboard simultaneously;
- At the same time, release these keys;
- Turn on your Mac by pressing the power button.
Note: The LED indicator on the MagSafe power adapter may change state or be temporarily disabled when the system control controller (SMC) parameters are reset.
After resetting the parameters of the system management controller, the computer should boot up in normal mode, but if this did not happen, then go to the instructions below.
Secondly, perform a keystroke to solve a black screen problem on a MacBook.
This method is rather strange and you should do everything exactly as described in the instructions below:
- Press the power button once - it will launch a shutdown dialog box that you will not see;
- Press the “S” button - this will put the computer to sleep;
- Press the power button and hold it until the computer turns off;
- Wait 15 seconds, and then press the power button again to start your Mac.
