Are you experiencing trouble accessing websites or noticing that your internet browsing isn’t as smooth as it should be on your Mac running Sonoma?
Often, these issues can be linked to outdated or incorrect information in your DNS cache.
This cache is like a memory bank that helps your Mac remember how to quickly find websites you have visited before.
However, when the information in the cache becomes old or incorrect, it can slow you down. Clearing it out can help resolve the issue.
It is rare thing to happen but we have got you covered. Let us learn to flush the DNS cache in macOS Sonama and earlier versions.
The process is simple and takes a few minutes at most to perform by yourself.
Flush DNS Cache in macOS Sonoma
You try these minor solutions before flushing the DNS cache on your macOS.
- Turn off your router and then turn it on after 2 minutes. Check if your internet problems are fixed.
- If you have recently changed your DNS then it can be the reason for the issues. You can change it using the tutorial we have given at the bottom.
- Try accessing websites in a different browser to see if it is a browser-specific issue.
When none of the above works, you can try clearing the DNS cache on macOS Sonama in the following manner.
1. Press Command and Space on the keyboard to open the Spotlight search.
