Is your MacBook restarting or powering off without warning? You’re not alone. At Boston Mobile Phone Repairs, we see many users face this issue — often due to overheating, battery problems, or software glitches.

🔍 Common Causes

Overheating under heavy load or in warm environments
Aging or failing battery with reduced capacity
Faulty power adapter or charging cable
macOS bugs after an update
Logic board or power circuit issues

🛠 Quick Fixes You Can Try

Check Your Charging Components
Use a known working charger and cable. Faulty adapters can cause sudden shutdowns.
Avoid Overheating
Keep your MacBook on a flat, hard surface. Clean vents to improve airflow.
Run macOS & App Updates
Go to System Settings → Software Update and install any pending updates.
Monitor Battery Health
System Settings → Battery → Battery Health. If “Service Recommended” is shown, consider replacement.
Reset SMC (for Intel Macs)
Shut down → Hold Shift + Control + Option + Power for 10 seconds → Release and restart.
