Tricks to fix a gray screen when booting Macbook

After a period of time using the Macbook, there are many problems, but the freeze on the gray screen is considered one of the most troublesome by many causes of this error. In fact, it's not always the gray screen error on the Macbook when starting up.

This booting issue is called the gray screen issue, as the screen will go gray during the boot-up phase when the problem occurs. Characteristic of this problem is that the screen changes from blue when powered to gray, although the blue screen may not be visible as it usually disappears very quickly.

Disconnect all peripheral devices

One of the most common causes that can cause gray screen issues is a problem with the peripheral or its cables. When a problematic peripheral is plugged into the Mac, it can prevent the autostart from happening and cause it to stall while waiting for the peripheral to respond.

The most common form of this problem is a problem with a peripheral or its cable causing one of the signaling batteries on one of the Macbook's ports to be 'stuck' at high / low voltage. , short circuit to ground or positive voltage. Any of these conditions can cause your Mac to 'freeze' during boot.

Therefore, please remove all peripherals for the duration of the procedure first, then turn off the Mac by pressing and holding the power button. If possible, unplug the ethernet cable, audio in / out cable, headphones, and any other peripherals, and then turn on your Mac again.

Note do not disconnect the keyboard, mouse or monitor. If the keyboard or mouse is connected via a USB hub, bypass that hub by plugging the keyboard and mouse directly into the Mac to check.

Or you can also try to replace peripherals by trying to change the mouse and keyboard you are using to an alternative device that you know is still working well, then restart your Mac. If you don't have a backup device, simply disconnect your mouse and keyboard, then restart it by pressing and holding the power key.

When using this trick if it works properly, reattach each peripheral, restart your Mac after each one, to verify that neither of them is causing the gray screen issue. head.

Boot your Mac using Safe Boot (safe boot)

If there are no faulty peripherals or cables, try booting your Mac using Safe Boot mode. To do that, first disconnect all peripherals except the mouse and keyboard.

During the whole Safe Boot process, the Mac will perform a check on the boot drive folder. If the directory is intact, the operating system will resume the boot process by loading only the minimum number of extensions needed to boot.

Remove all but the minimum amount of RAM from the Mac
