Flushing the DNS cache in macOS Ventura is a straightforward process that can help resolve internet connectivity issues. By performing a few simple steps in the Terminal application, you can clear the DNS cache and force your computer to update its DNS records.
Flushing DNS Cache in macOS Ventura Tutorial
Before we dive into the steps, let’s understand what flushing the DNS cache does. It clears out the stored IP addresses and domain names that your computer has visited. This can resolve issues with outdated or incorrect DNS information that may prevent you from accessing websites.
Step 1: Open Terminal
Open the Terminal application on your Mac.
The Terminal application is located in the Utilities folder within the Applications folder. You can also search for it using Spotlight by pressing Command + Space and typing "Terminal."
Step 2: Enter the Command
Type the following command into Terminal: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
This command combines two actions. The first part, sudo dscacheutil -flushcache, clears the DNS cache. The second part, sudo killall -HUP mDNSResponder, restarts the DNS service.
Step 3: Enter Your Password
When prompted, enter your administrator password and press Return.
You won’t see the characters you type for the password, which is a security feature. Just type it in and press Return.
Step 4: Close Terminal
After the command has been executed, you can close the Terminal application.
You’ve successfully flushed the DNS cache on your Mac running macOS Ventura.
After completing these steps, your Mac will have a fresh DNS cache. This means it may take a few extra seconds to load websites the first time as it rebuilds the cache, but it can resolve connectivity issues you were experiencing.
