What Causes MacBook Performance Issues?

Here are some of the most common technical reasons your MacBook might be underperforming:

1. Outdated macOS or Software

Running an older version of macOS can lead to compatibility issues, security vulnerabilities, and slower performance. Updates often include performance improvements and bug fixes.

2. Too Many Background Processes

Apps running in the background (especially browser tabs, cloud sync tools, or startup items) can consume CPU and memory, slowing down your system.

3. Overheating and Fan Noise

Dust buildup, poor ventilation, or failing thermal paste can cause your MacBook to overheat. This triggers the fans to run at full speed and may throttle performance to prevent damage.

4. Failing SSD or Hard Drive

A degraded or nearly full drive can cause slow boot times, app lag, and even data loss. Older iMacs and MacBooks with HDDs or Fusion Drives are especially vulnerable.

5. Corrupted System Files or Malware

Although rare on macOS, malware or corrupted system files can cause erratic behaviour, crashes, or slowdowns.
