The MacBook is a reliable, powerful laptop that has become the choice for many professionals, students, and everyday users alike. Unfortunately, like all technology, it isn’t perfect.
A common issue that MacBook users have been reporting for a while now is their device restarting after going into sleep mode. Although this could simply be a glitch or an easy fix, there are also several potential causes behind why your Mac may be acting up.
1. Outdated Operating System – You can experience a number of issues when running an outdated version of macOS on your MacBook.
Make sure you keep your system up to date to avoid any unnecessary headaches.
FaceTime not working on MacBook or any other app to run properly is a solid indicator that there are problems with the macOS version as well. You can test some apps to confirm your suspicions. If the suggestion proves correct, do not wait and update the operating system as soon as you can.
2. Overheating – When your MacBook gets too hot for its own good, it will automatically shut itself off and restart in order to prevent any further damage from occurring.
Put effort into keeping your laptop in a cool environment and free from dust buildup, as dirty fans can cause the device to overheat more quickly than usual.
3. Bad Battery – If you’re having difficulty getting your device to stay awake and running for extended periods of time even when plugged in, then the battery may be dying out and needs replacing soon.
4. Corrupted Files – Faulty software or corrupted files can cause random restarts on your MacBook as well as other problems such as freezing or lagging during operation.
Run system diagnostics to identify any files that may need repair or delete and replace them with fresh versions if possible.
5. Third-Party Peripheral Interference – External devices, such as hard drives or USBs, have been known to interfere with the normal operations of some MacBooks.
The interference causes the laptop to randomly restart without warning or prompt upon waking up from sleep mode due to power surges or driver conflicts between hardware components linked up through USB ports or Bluetooth connections.
To resolve this issue, disconnect any external peripherals while troubleshooting and check if the problem persists afterwards before reconnecting them back again one by one until you find out which particular device is causing the conflict with your machine during wake-up operations from sleep mode.
6. System Integrity Protection (SIP) – SIP is a security feature built into macOS designed to help protect certain folders and processes from being modified by malicious software or viruses.
Having said that, SIP can also cause issues when making changes manually, since it blocks permissions that would normally have been granted had SIP not been enabled on the device in the first place.
To resolve this problem, try disabling SIP by booting into recovery mode (using Command + R) and selecting “Utilities” followed by “Terminal” on the top menu bar once inside recovery mode.
Then type in “csrutil disable” and press the Enter key, then reboot for the changes to take effect.
7. Third-Party Peripherals – Faulty third-party applications installed on one’s machine can lead to random restarts, primarily once the Mac turns on again after being idle.
Make sure all of the computer apps are working correctly before attempting any other solutions.
Also, try uninstalling potentially problematic programs temporarily until the problem resolves itself.
8. Hard Drive Issues – Your hard drive stores data used by your system, so if something has gone wrong with it, then chances are one won’t be able to work properly, and this could lead to unexpected shutdowns, including restarts after waking up from sleep mode.
To fix this, run disk maintenance tools such as the built-in macOS utility, Disk Utility, or the third-party tool, such as CleanMyMac X, regularly in order to ensure that both internal storage units are healthy, optimized, clean, and not damaged beyond repair before proceeding with any other solutions suggested in this article.
9. Bad RAM – Faulty RAM can cause your system to crash during operations or even restart itself without warning, especially once it wakes up from sleep.
If your MacBook has been experiencing random restarts for some time now, it’s worth testing its memory (RAM) by running a tool such as Memtest86+ to identify any potential issues that may require attention to be fixed.
