Mac Troubleshooting FAQ

1. Why is my Mac running slow?

Answer: Slow performance on a Mac can occur due to limited storage, too many apps running at startup, outdated software, or background processes consuming resources. To fix this:

• Remove unnecessary startup items (System Settings → Users & Groups → Login Items).

   

• Free up disk space by deleting old files or using the built-in Storage Management tool.

   

• Close unused apps and browser tabs.

   

• Keep macOS updated to the latest version for performance improvements.

   

2. Why won’t my Mac start up?

Answer: Startup issues may be caused by corrupted system files, faulty hardware, or software conflicts. Try these steps:

• Perform a Safe launch(Shift key while starting your Mac).

   

• Reset NVRAM/PRAM (Option + Command + P + R at startup).

   

• Run Disk Utility → First Aid to repair your startup disk.

   

• Disconnect external devices and try restarting again.

   

3. Why is my Mac overheating or fans running loudly?
