Does force shutdown damage Mac?
A force shutdown, also referred to as a hard reset/shutdown, does not impact your Mac's hardware. Especially when all modern Macs are configured with Solid-state drives (SSD), the chances of being broken are even smaller.
However, forcing your Mac to shut down will cause you to lose unsaved files or progress in open applications and may potentially corrupt system files if done repeatedly.
If this is the first time your Mac got stuck, or it doesn't occur often, a forced shutdown will hardly bring any damage to your Mac file system because advanced file systems such as APFS or HFS+ features crash protection.
In fact, many applications like Microsoft Word also power their users with a backup of the unsaved work that you can restore when reopening the app.
Note: Continual Mac force shutdown may cause kernel panics when there's major data corruption in the operating system.
How will macOS react after a force shutdown?
After experiencing a forced shutdown, macOS will run a file system check to fix potential errors the next time you turn on your Mac. That's also why starting up after forcing Mac to shut down takes longer.
Sometimes, you may see messages reading "Previous Shutdown Cause" with a number in the built-in Console app, such as Previous Shutdown Cause - 3. The number 3 means that a hard shutdown turns off the Mac.
If you have the suspicion that your Mac hard disk may have problems after a force shutdown or in general, you can run First Aid in Disk Utility to make a diagnosis.
What to do before a force shutdown on Mac?
Use the tips below to lower the possibility of losing data before forcing your Mac to shut down:
1. Save files or projects you are currently working on.
You can press the Command + S keystroke to save open files or take a photo of the progress in case the keyboard combination doesn't work.
2. Safely eject external storage devices if possible.
To avoid causing damage to the data on your external storage, you can safely eject them by dragging the drive icon on your desktop to Trash or clicking the Eject button next to your drive name in Finder.
3. Force quit frozen apps on Mac.
Before heading to a Mac force shutdown, it may be better to force quit unresponsive apps on Mac first because that could be the culprit making your Mac frozen.
