Part 1: Check the Hardware

Before you try any software fixes, it’s important to rule out any hardware problems that might be causing the lines on your MacBook screen. Here are some steps you can follow to diagnose the hardware issue:

Step 1: Check the cable connections

Sometimes, loose or damaged cable connections can cause lines or distortions on your MacBook screen. To check if this is the case, follow these steps:

1. Shut down your MacBook and unplug all external devices.
2. Use a soft cloth to clean the MacBook screen and remove any dust or debris.
3. Check the cable connections between your MacBook and the external display, if you are using one. Make sure the cables are firmly plugged in and not damaged or bent.
4. If you are using a Thunderbolt cable, try using a different one to see if the problem persists.

Step 2: Run the Apple Hardware Test

The Apple Hardware Test is a built-in diagnostic tool that can help you identify any hardware issues on your MacBook. Here’s how to run the test:

1. Restart your MacBook and hold down the D key while it starts up.
2. Follow the on-screen instructions to run the hardware test.
3. If the test detects any hardware problems, it will provide you with an error code and a description of the issue.

Step 3: Contact Apple Support

If you have tried the above steps and still have lines on your MacBook screen, it’s time to contact Apple Support. They can help you diagnose and fix any hardware issues that might be causing the problem. Make sure to have your MacBook’s serial number and warranty status ready before you call or chat with Apple Support.

Part 2: Fix the Software

If you have ruled out any hardware problems and still have lines on your MacBook screen, the issue might be caused by software glitches or conflicts. Here are some steps you can follow to fix the software issue:

Step 1: Restart your MacBook

Sometimes, a simple restart can fix software glitches and refresh your MacBook’s system. Here’s how to restart your MacBook:

1. Click on the Apple menu on the top-left corner of your screen.
2. Select Restart from the drop-down menu.
3. Wait for your MacBook to shut down and restart.

2. Select System Preferences from the drop-down menu.
3. Click on Software Update.
4. If there is any update available, click on Update Now.
5. Wait for the update to download and install.

Step 3: Reset the NVRAM and SMC

The NVRAM (Non-Volatile Random Access Memory) and SMC (System Management Controller) are two components of your MacBook that store and control various settings, such as the screen resolution, brightness, and color. If these components become corrupted or misconfigured, they can cause lines or distortions on your MacBook screen. To reset the NVRAM and SMC, follow these steps:

1. Shut down your MacBook.
2. Press the power button to turn it back on.
3. Immediately press and hold the following keys: Command (⌘) + Option + P + R.
4. Keep holding the keys until you hear the startup sound twice.
5. Release the keys and let your MacBook boot up normally.

Step 4: Boot in Safe Mode

Booting your MacBook in Safe Mode can help you isolate and troubleshoot software issues that might be causing lines or distortions on your screen. Here’s how to boot in Safe Mode:

1. Shut down your MacBook.
2. Press the power button to turn it back on.
3. Immediately press and hold the Shift key.
4. Keep holding the Shift key until you see the login screen.
5. Release the Shift key and log in to your MacBook.
6. Check if the lines or distortions are still present.
7. If they are not present, it means that a third-party app or extension might be causing the issue. Try disabling or uninstalling any recently installed apps or extensions to see if the problem goes away.
