Here are the five easy Mac terminal command lines you can use to clean and speed up your macOS device.
1. Clear up RAM memory
For optimal performance, it’s essential to free up inactive Random Access Memory (RAM) on your MacBook. Inactive RAM is occupied by previous applications and system processes, even when they are not in use. To free up inactive RAM, use the following command in Terminal:
sudo purge
2. Flush DNS Cache
Your Mac stores IP addresses of websites you visit in the Domain Name System (DNS) cache. Over time, outdated entries in the cache may cause issues, such as 404 errors when accessing certain webpages. To ensure you get the latest nameservers and improve website accessibility, regularly flush the DNS cache using the following Terminal command:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder;
3. Clear user log files
macOS maintains log files for crash reports and error reporting purposes. As you use your MacBook, these log files accumulate and take up disk space. Clearing user log files can significantly improve macOS performance and free up valuable disk space. To remove these log files, follow these steps in Terminal:
cd ~/Library/Logs
sudo rm -rf ~/Library/Logs/*

4. Remove System Logs
While Apple automatically cleans up system log files periodically, sometimes they can still occupy substantial space, such as 10GB. Regularly clearing system logs can prevent unnecessary disk space consumption. To remove system logs, use the following Terminal command:
sudo rm -rf /private/var/log/*
5. Restart your Mac regularly
Regularly restarting your Mac is a good practice to maintain its performance. Rebooting your Mac allows it to clear cached data, refresh system processes, and start with a clean slate. It’s recommended to restart your Mac at least once a week. To reboot your Mac, use the following command in Terminal:
sudo shutdown -r now
By following these five easy Terminal command lines, you can efficiently clean and speed up your macOS device. These simple actions can make a significant difference in your MacBook’s performance and overall user experience. Regular maintenance and optimization will keep your Mac running smoothly and efficiently for years to come.
