MacBook Slow
You’re experiencing a slow MacBook. Below are several troubleshooting steps to resolve this common problem and get your MacBook running at peak performance once again. These solutions work for all models of MacBooks, including the MacBook Air and the MacBook Pro, unless otherwise specified.
First Steps
Try the following steps before proceeding:
- Reset the System Management Controller (SMC)
- Reset the PRAM or NVRAM
- Repair your startup disk
- Run Apple Diagnostics
Possible Causes
Storage Is Full
If your device is running low on storage, it can affect performance.
Try using OmniDisk Sweeper or DiskInventoryX to identify and delete unnecessary files, or use Time Machine snapshots to free up space.
For a permanent fix, consider upgrading to a larger hard drive or solid-state drive (SSD).
Malware
Malware can slow down your computer by consuming resources and harming system functions.
Use an antivirus program to scan for and remove malware. Avoid using multiple antivirus programs, as they can conflict with each other.
Multiple Antivirus Programs
Having multiple antivirus programs installed on your MacBook can cause conflict and slow down your system.
It’s recommended to use only one reputable antivirus program.
Hardware Is Underpowered
If your MacBook does not have adequate hardware, such as memory (RAM) or processing power, it may struggle to perform demanding tasks.
Consider adding additional RAM or swapping out your logic board with one that supports more RAM.
Overheating
Overheating can cause your MacBook to slow down as a protective measure to prevent damage.
Check for dust buildup in the vents and fans, and use a cooling pad to help keep your MacBook from overheating.
If your MacBook is overheating frequently, you may need to replace the thermal paste on your CPU or have it inspected by a professional.
Missing Sensor Data
Missing sensor data can trigger a protective mode in your MacBook, causing it to slow down.
Have your MacBook diagnosed by a qualified technician to identify the cause of the missing sensor data.
Faulty Storage
Faulty storage, particularly hard drives (HDDs), can cause performance issues and data loss.
If you experience clicking sounds or other abnormal noises coming from your MacBook, it’s possible that your HDD is failing.
Consider replacing your HDD with an SSD for improved performance and reliability.
Faulty Fan
A faulty fan can lead to overheating and performance issues.
If your MacBook is unusually quiet or makes strange noises, it’s possible that the fan is malfunctioning.
Contact Apple or a qualified repair technician for a fan replacement.
