More solutions if your MacBook Pro won't turn on
Force restart your Mac
What type of software is adobe photoshop. 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 MacBook lid and press a few keys on a keyboard. It might help, but if it doesn't in no way you should panic — first let's perform a quick force restart.
1. Hold down the Power key for about 6 seconds.
2. 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 even remotely connected with boot process (like your MacBook won't turning 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 make 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 to 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 for this is to use the app called CleanMyMac on your machine and run Repair Disk Permissions command.
- Download the app (it's free to download)
- Install it and go to 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. 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 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 Shift + Option + Control and Power key at the same time.
- Let go of the keys and boot your Mac again.
