Troubleshooting MacBook Pro White Noise Pixels

There's no denying that MacBook Pro is an exceptional device, but like any technology, it can sometimes exhibit issues. One such problem is experiencing white noise pixels when booting up your MacBook Pro. This article will discuss what could be causing this issue and how to resolve it.

What Could Be Causing White Noise Pixels?

There are a few possible reasons for the occurrence of white noise pixels on your MacBook Pro screen during boot-up. Some of them are:

  1. GPU or Graphics Card Issues: The GPU (Graphics Processing Unit) in your MacBook Pro might not be working as it should due to various reasons such as overheating or driver issues.

  2. Screen Damage: The MacBook Pro's screen could have been physically damaged, which might be the source of the white noise pixels.

  3. Software Glitches: Sometimes, software issues can cause white noise pixels to appear on a MacBook Pro.

How to Fix White Noise Pixels on MacBook Pro?

Here are some potential solutions to fix the white noise pixels when booting up your MacBook Pro:

  1. Reset the NVRAM/PRAM: Resetting the Non-Volatile Random-Access Memory (NVRAM) or Parameter RAM (PRAM) can help solve many display issues, including white noise pixels. To do this, follow these steps:
  • Shut down your MacBook Pro.
  • Press and hold the Option, Command, P, and R keys.
  • Turn on your MacBook Pro while still holding down these keys.
  • Keep them pressed for about 20 seconds, after which you'll hear the startup chime.
  • Release the keys and check if the white noise pixels issue is resolved.

  1. Check for MacOS Updates: Sometimes, updating your MacBook's MacOS can fix display issues. Go to the Apple Menu > System Preferences > Software Update and install any available updates.

  2. Test for GPU Issues: Running Apple Diagnostics can help determine if a GPU issue is causing white noise pixels. First, make sure your MacBook Pro is connected to a power source and follow the steps below:

  • Shut down your MacBook Pro.
  • Press and hold the D key.
  • Power on your MacBook Pro while still holding the D key.
  • Apple Diagnostics will start running automatically. Once completed, you'll receive a report if there are any issues found.

  1. Inspect the Screen: If you suspect screen damage as the cause of white noise pixels, consider bringing your MacBook Pro to an authorized Apple service center to repair or replace the screen.

  2. Reinstall MacOS: If none of the above steps help, you may need to reinstall macOS, as the issue could be software-related. Before doing this, make sure to back up all your data.

In Conclusion

Having white noise pixels during boot-up on your MacBook Pro can be frustrating, but resolving the issue can be achieved through various troubleshooting steps. If the problem persists even after trying the above fixes, it's best to consult an Apple certified specialist.
