If your Mac stalls on a plain gray screen, it can be quite frustrating. What’s more bothering is the absence of an error message. What you find in such cases along with the gray screen is either the Apple logo or a spinning globe or an image of a folder with a question mark or maybe a prohibitory sign. In all such cases, your Mac appears to be stuck, and you can’t skip the page to move ahead. You won’t hear any unusual fan noise or the optical drive spinning up/down; it’s just a Mac screen which won’t move forward to the login page.
So what do you do? First, you should try to find out all the possible causes behind a gray screen on Mac. Let’s start from there.
Reasons behind the MacBook Pro Gray Screen of Death
There could be several reasons behind a gray screen on your Mac:
A defective or unauthorized peripheral device can cause the MacBook Pro gray screen of death. When a defective peripheral device or cable is plugged into your Mac, there are high chances that it will stop the machine from continuing to the normal startup sequence. This causes your Mac to stall at the gray screen while waiting for the defective peripheral device to respond to the command.
Peripheral devices which do not have an updated firmware can lead to MacBook Pro gray screen with circle slash.
If you have installed any new program on your Mac and it is not functioning properly, it will cause MacBook gray screen error.
If you’re facing the MacBook Pro grey screen after login or at startup, there are multiple ways to try and fix the issue. Take a look at some in the next section.
How to repair Gray Screen on Mac?
Method 1: Disconnect all External Peripheral Devices
defective peripheral or cable causes the signaling pins on Mac’s ports to get
stuck in a single condition (low, high, or neutral). This freezes your Mac during the boot process. You need to remove
all the peripherals one by one using below-mentioned steps.
Shut down the Mac by pressing the Power button for 3-5 seconds.
Now remove all the peripherals from your Mac. You can remove the audio cables, headphones, Ethernet cables, etc.
Now press the powerbutton to switch on the Mac.
If your Mac goes to the normal login screen, then you need to find the bad peripheral by reconnecting one peripheral at a time. Then restart the Mac and see if you’ve spotted the bad peripheral.
Method 2: Use Disk Utility to Repair the Disk
You need to check if your hard drive (or SSD) is causing the gray screen on your Mac. To confirm this, you need to run the Disk Utility. It will show if your start-up drive is having any issues. You can follow the below-mentioned steps to do so.
Shut down your Mac by pressing the Power button for 3-5 seconds.
Now press the Command key and R key simultaneously to start the Mac.
Your screen will show up the “macOS Utilities” pop-up. You need to choose the “DiskUtility” option.
Choose macOS start-up using the left column of Disk Utility.
It will start the Disk Utility program and check if any hard drive issues are there.
Once this completes, you can start your Mac and check if the gray screen problem is resolved.
Method 3: Start Mac Using Safe Boot
Starting your Mac using Safe Boot will perform some common diagnostics to eliminate the gray screen of death and ensure that your Mac is running fine. It makes sure that all the minor glitches are excluded from the startup to run your Mac. You can follow the below-mentioned steps to do so.
Shut down your Mac by pressing the Power button for 3-5 seconds.
Now restart it by holding the Shift key.
While the Safe Boot is completing its task, you can press the “Shift + Command + V” key. This will show you the verbose mode and Safe Boot mode’s current status.
Once the desktop gets displayed completely, you need to restart your Mac from the Apple menu.
Method 4: Reset PRAM
Resetting the PRAM will reset your hardware to its default Mac settings. You can follow the below-mentioned steps to do so.
Shutdown your Mac by pressing the Power button for 3-5 seconds.
Now remove all the peripherals from your Mac.
Now reset the PRAM/NVRAM of your Mac as follows:
Shutdown your Mac.
Turn it on and then press and hold the Command, Option, P, and R keys together immediately after hearing the startup sound
Hold these keys until the computer restarts and you hear the startup sound for a second time. Then release them.
Restart the Mac now and connect all the peripherals again which you have removed in step 2.
