Why Does the iMac Keep Freezing and Restarting?
There are several possible causes for repeated freezing and restarts. Some are software-related, while others may be linked to hardware components. Here are some common reasons:
- Corrupted system files – Even after a restore, some files may remain damaged.
- Third-party apps – Incompatible or outdated apps can create kernel panics that cause restarts.
- Faulty RAM or storage – Hardware problems often lead to freezing under heavy tasks.
- Overheating issues – Dust buildup or cooling system failures may silently trigger restarts.
- macOS bugs – Sometimes, new updates introduce conflicts rather than fixing them.
Step-by-Step Troubleshooting Guide
To fix the issue, follow these practical steps in order:
1. Run Apple Diagnostics
- Restart your iMac while holding the D key.
- This built-in tool will scan for hardware issues such as memory or logic board errors.
2. Boot into Safe Mode
- Press and hold Shift while restarting.
- Safe Mode only loads essential files, helping you test if third-party apps are causing the crashes.
3. Check Login Items
- Go to System Settings > General > Login Items.
- Remove any apps that may launch at startup and cause conflicts.
4. Reset PRAM and SMC
- These resets often fix freezing and power-related issues.
- Hold Option + Command + P + R during restart to reset PRAM.
- For SMC, shut down your iMac, unplug the power, wait 15 seconds, and reconnect.
5. Monitor Hardware Health
- Use Activity Monitor to check if your CPU or memory is overloading.
- If you hear no fan activity during heavy use, your cooling system may need service.
