After installing the macOS 10.14 updates, a user can run into issues with the Mac’s sleep and wake functions wherein the Mac refuses to wake when expected or the OS fails to launch after going to sleep, even after the power button or any button on the keyboard is pressed ad nauseam.

The Sleep and Wake activities of Macs are normally regulated by user settings, app activities, connected devices and networks. That implies that most users encountering this issue might think it’s a technically intricate task to fix a Mac that won’t wake up on macOS 10.14.

If you’re still short of answers as per how to fix macbook won’t turn on on macOS 10.14, you can get cracking on the following steps to find your way around:

1. Disable System Hibernation:

Note that the hibernation mode is only a preventive measure to prevent the loss of data during a loss of power, you might be able to do without its intervention. To turn off the hibernation mode, run the following commands in the OS X Terminal:

sudo pmset standby 0

sudo pmset autopoweroff 0

These two commands disable the settings of the hardware responsible for the hibernation mode. These include the Apple’s main standby mode option, and a functionality installed in accordance to regulations of European energy. To revert the settings, simply reset your Mac’s system management controller. Another way is to run the commands again, this time replacing the '0' with '1'.

2. Reset FileVault

A glitch may impede the storage and retrieval of file contents on the hard disk during hibernation, causing conflicts between full disk encryption protocols like FileVault, which in turn prevent the authentication and loading of hibernation files, leading to a crash as the system wakes up. To resolve this, disable the full-disk encryption protocols, and re-enable them if the hibernation works fine after the disk is fully decrypted.

3. Clear Out Hibernation Files

When the system figures that a hibernation file (files written on the hard disk by the hibernation function) is missing, it recreates the file. But if it does so erroneously, it might damage the file, preventing reading from the system when waking up. To fix, force the system to recreate the files again by the run of the following command:

sudo rm /var/vm/sleepimage
