MacBook Pro White Noise Screen Upon Waking: Causes and Fixes

Jan 23, 2024

As many MacBook Pro users are familiar, seeing a white noise screen when first waking up the device can be a cause for concern. However, this problem is quite common and can often be resolved through simple troubleshooting or more advanced methods if necessary. This article will explain what may be causing the white noise screen and offer potential fixes to this frustrating issue.

Possible Causes for the White Noise Screen

  1. Sleep mode: When your MacBook Pro goes into sleep mode, the display is turned off to save power. When waking up the device, it takes a few moments for the display to show the login screen, and during this time, the white noise screen may appear.
  2. Graphics issue: Another possibility is a temporary issue with the graphics card or graphics driver. This is more common in older MacBook Pros, where the graphics card may have degraded over time.
  3. Software glitch: The white noise screen could also be caused by a minor software glitch, which can be cleared up with simple troubleshooting steps.

Potential Fixes for the White Noise Screen

  1. Restart your MacBook Pro: One of the simplest fixes is to restart your MacBook Pro. This effectively resets the system and clears up any minor software glitches that could be causing the white noise screen.
  2. Reset your System Management Controller (SMC): Sometimes, a simple restart isn't enough to resolve the issue. In these cases, resetting the SMC can be helpful. To reset the SMC, first shut down your MacBook Pro, then plug it into a power source. Press and hold the Shift + Control + Option keys and the power button simultaneously for about 10 seconds, then release the keys and start your MacBook normally.
  3. Update your Mac's software: If the problem persists, check for and install any available macOS updates, as these may contain fixes for bugs that could be causing the white noise screen.
  4. Run Apple Hardware Test: If none of the above steps work, you may need to test your hardware. To do this, restart your MacBook Pro and hold down the D key during the startup process. Follow the on-screen instructions to perform a thorough hardware diagnostic.

In most cases, simple troubleshooting steps will resolve the issue of a white noise screen upon waking your MacBook Pro. However, if these steps do not work, it may be necessary to consult with Apple Support or an authorized Apple service provider for further assistance.
