Is your Mac having insomnia issues? Trouble sleeping through the night? Like babies and humans, Macs can get finnicky about sleep patterns and may not shut down, or go to sleep properly. No matter how much you tweak the System Preferences, sometimes it takes a little bit of trickery under the hood to get the Mac going the way it should. We'll show you how to find rogue apps in the background, change the lid closed action, and prevent your Mac from sleeping.
If you've ever used a large file discovery tool like Daisy Disk, you may have stumbled upon a peculiarly large filed dubbed sleepimage. This file is a by-product of Safe Sleep and it's basically a saved state of your Mac's memory when it goes to sleep. MacBooks especially use this function your contents before the battery completely loses its charge. When you start up your system, the Mac will restore this data from the sleepimage file.
Regardless of how important this file may sound, it's actually completely unneccessary. So why not free up some hard disk space by eliminating it? Read on to find out how.
