With that said, there are some known reasons of the issue that have been reported by other users. We’ll go through these potential causes in detail down below so that you have a better understanding of what could potentially have caused the issue in your particular case. However, in some scenarios, your issue may not correlate to the causes mentioned down below, but rest assured, you will probably get it fixed after trying the various methods that we will be listing. So, without further ado, let us get started. Now that we have gone through the possible causes of the issue, let us get into the different methods that you can implement to resolve the issue. Please make sure that you go through all of them to get an early resolution.
Method 1: Unplug External Hardware
Before we get into the much more complicated and complex methods, the first thing that you should do is unplug any external peripheral that is connected to your Mac. It often happens that these peripherals cause certain issues and your Mac, as a result, gets in trouble. So, before you try the rest of the methods that we are going to mention down below, just go ahead and unplug anything that is connected except the keyboard, mouse, and all the other necessary stuff required to boot. Once you have done that, reboot your system and see if that fixes the issue. If the Mac boots up this time, it means that one of those connected peripherals was causing the issue.
Method 2: Boot via Safe Boot
Safe mode is a feature that is widely used to troubleshoot problems when the actual cause isn’t really known. With the help of a safe boot, you are able to decide whether the issue that you are facing is caused by any third-party software that you have on the system or if it is something else. What safe boot does is it actually starts your Mac without any third-party software running and just the basic stuff required for the OS to boot up. Follow the instructions below to start your Mac in safe mode:
Method 3: Use the Integrated GPU
As it turns out, in some cases the Mac’s GPU can be the culprit which is causing the laptop to not boot up properly. This has been reported by various users and there’s an easy workaround to this. Basically what you have to do is to force the Mac to use the integrated GPU by heating up the primary GPU.
Method 4: Use Disk Utility
As it happens, sometimes a corruption in the files or a bad disk can cause the Mac not to boot up properly and get stuck on a white screen. In such a case, it is often useful to run the disk utility which searches for any errors in your disk and then tries to fix them. Follow the instructions below to run the disk utility:
Method 5: Reset NVRAM or PRAM
NVRAM or PRAM are small amounts of memory that store different settings of your Mac. There are various cases where issues are caused by these memory locations and thus resetting them often fixes several problems. This has worked for some of the users so it might work for you as well. The instructions are the same for both NVRAM or PRAM. Follow the steps provided down below:
