Part 1. Common Ways to Fix Mac Frozen Screen

It doesn’t matter if your Mac is stuck on the loading screen or whether it has got a white screen of death – there are some solutions that seem to fix Mac screen issues of all kinds. Before we discuss various issues and solutions individually, let’s quickly consider some recommended solutions, suggested by the leading experts.

Solution 1: Disconnect all peripheral devices

As surprising as it might sound, this is the easiest fix to a Mac screen issue. If you are using a third-party peripheral device (like a Bluetooth speaker or mic), then it can tamper with the booting of the system at times. Simply remove all the peripheral devices and only connect a mouse and keyboard to your desktop (genuine Apple products). Once it is done, try to restart Mac and check if it boots normally or not.

Solution 2: Forcefully restart Mac

If your Mac is stuck on the loading screen or has got a white/black/gray screen of death, then you can consider turning it off. If there was a minor issue with the firmware, then a forceful restart would fix it. This will reset the present power cycle of the system and let you get back full control on it.

  1. To forcefully turn off Mac, press and hold the Power key. It is mostly located at the top of the keyboard.
  2. If it won’t work, then you can just remove the battery of your notebook or disconnect the main power supply of the desktop as well.
  3. Wait for at least 15-20 seconds and press the Power key again to turn it on.

Solution 3: Boot Mac in a Safe Mode

If there is a problem related to a certain process or application in your Mac, then you should consider booting it in the safe mode.

Solution 4: Reset PRAM

PRAM, which stands for Parameter Random Access Memory, is one of the major components in Mac. Apart from handing other vital system processes, it is also responsible for Mac’s booting too. Therefore, if you have got a black, white, or gray screen on Mac, then you should consider resetting its PRAM first.

  1. Firstly, turn off your Mac by long pressing the Power switch and wait for a few seconds.
  2. Turn it on and press the P + R + Option + Command keys at the same time as Mac restarts.
  3. Keep holding them until your Mac would restart. Once you hear the startup chime for the second time, release the keys. This means the system has been started with new PRAM settings.

Solution 5: Repair the Startup Disk

Most of the times, an issue like Mac stuck on login screen usually happens due to a corrupt or malfunctioning disk. Since Mac lets us repair a disk on its own, you can take the assistance of Disk Utility to do the same. Here’s how you can fix Mac black/white/green screen by repairing its startup disk.

  1. Turn on your Mac or restart it if it is already power on.
  2. As it restarts, press and hold the Command + R keys at the same time for a few seconds.
