Users are able to hear the Mac startup as the fans start and the keyboard lights turn on. However, the display would remain black and nothing would happen. In such a case, to get the display back, users were forced to perform a hard reboot after which the Mac would start up normally. Now, this is not the intended behavior and this could either be caused by an operating system bug or in rare cases, your external hardware. As it turns out, in some cases, the issue would appear to be caused by a bug with the macOS Catalina which would prevent the device from waking up normally after sleeping. However, that is not it. It also happens to be caused by external hardware at times. Especially, if you have been using the J5create Dock. The extensions of the dock stored on your Mac can cause the issue as well, therefore, you will have to delete them. With that said, let us go through the different methods that you can use to get rid of the problem. So, without further ado, let us get started.
Method 1: Delete J5create Drivers Extensions
If you have used the J5create dock (or any other hardware from J5create) or are still using it, chances are that your issue could be because of the extensions of the dock stored on your Mac. Often external hardware stores their extensions in your Mac’s library folder. Therefore, in such a case, what you have to do is simply remove the extensions and then try waking up your Mac to see if the issue persists. To do this, follow the instructions down below:
Method 2: Reset NVRAM
As it turns out, NVRAM is a small amount of non-volatile memory that is used by Mac devices to store some specific settings so that they can be accessed quickly. In some scenarios, black screen issues can be caused by the NVRAM as well in which case you will have to reset it. This is completely safe and you won’t be losing any data so no need to worry. To reset NVRAM, follow the below instructions:
Method 3: Update your Mac
As we have mentioned above, in some cases the issue can be due to an operating system bug. This has been reported by several users and thus updating your Mac to the latest version available often fixes the issue. Therefore, you will have to check if there are any updates for your Mac. This can be done pretty easily from System Preferences. Follow the instructions down below to check for any updates:
Method 4: Boot into Safe Mode
As it turns out, if the above methods do not work out for you, what you can do is launch your Mac into Safe Mode and then let it sleep in Safe Mode. It should wake up normally in safe mode. Once you have done that, reboot your system normally without getting into the safe mode. Hopefully, that will fix your issue and you won’t experience it anymore. This has been reported by a user who was facing a similar issue on macOS Catalina. Follow the instructions down below to know how to do all of this:
