Check For Brightness And Power

Before you do anything, check the most apparent options. Is your screen’s brightness set to the lowest setting? Check to see whether your Mac is turned on. Is it enabled when you use an external display? Is your Mac hooked into a power source? Also, is there a battery drain if you have a MacBook? You may only sometimes have your Mac in sleep mode. The screen’s brightness is most likely only adjustable lower down. It’s also conceivable that you shut down your MacBook. It will instantly fix your sleep wake loss dreams by altering the brightness of your Mac or turning it on.

Reinstall macOS

If you have previously altered the brightness of your display, tested your connection, and reset your Mac, and it still wakes up to a black screen, you may need to reinstall macOS. Reinstall macOS without totally formatting your Mac. However, the usual guideline is to offer a backup before resetting your operating system.

Reset Mac’s FileVault

A bug might prevent your device from obtaining all the necessary content and files on your hard drive to wake up your Mac from sleep. As a result, when it wakes up, it conflicts with your full-disk security policies, such as FileVault, and your system fails. To fix this issue, disable your full-disk encryption techniques. The hard drive should then be decrypted using third-party software. After that, re-enable the protocols for full-disk encryption. See how this resolves the problem.

Disable System Hibernation

Aside from sleep mode, which is also an option, your Mac includes a hibernation mode. The hibernate mode is a useful defensive mechanism that allows you to preserve information during a power outage. You may, however, go on with your normal activities even if this mode is not enabled. Therefore, consider disabling hibernation mode if you don’t need to hibernate your Mac and usually have difficulties waking it up. To accomplish this, open your OS X Terminal and follow these steps.

  • sudo pmset autopoweroff 0
  • sudo pmset standby 0

These commands will deactivate the hardware configuration in charge of activating hibernation mode. If you ever want to activate this option again, execute the commands in your OS X Terminal, but this time modify the value from 0 to 1.

Clean System Junk

System garbage, such as cache archives, failed updates, diagnostic reports, and unused file logs, may accumulate on your system over time. If they are not deactivated, they will consume valuable disk space and, worse, interfere with your machine’s functionality. To remove system garbage, you must download and install a third-party app. Then, use it on your Mac to search quickly, empty your trash, and eliminate any unnecessary files from all normal places.
