“Your Computer Restarted Because of a Problem”
What This Means (In Plain English)
Your Mac had a serious error and restarted itself. This is the Mac equivalent of a "blue screen." Your files should be safe.
Common Causes

- •A faulty external device
- •Hardware issue (like failing RAM)
- •A bug in macOS or an app
How to Fix It — Step by Step
- 1
Click "OK" on the restart message.
- 2
If it happens once, it may have been a one-time glitch — continue using your Mac normally.
- 3
If it happens again, check for macOS updates: Apple menu > System Settings > Software Update.
- 4
If you recently installed new software or connected new hardware, try removing it.
- 5
Disconnect all external devices (USB drives, printers, etc.) and see if the problem continues.
- 6
If it keeps happening, reset NVRAM: shut down, then press and hold Option + Command + P + R as you turn it on, for 20 seconds.
- 7
If the problem persists, contact Apple Support or visit an Apple Store.
How to Prevent This in the Future
