Safari browser slows down after macOS Sonoma upgrade? Don't worry, this guide will help you solve the problem! After Sonoma system updates, Safari's slow running becomes a common problem. But that doesn't mean you need to give up on system upgrades. This article will explore the reasons why Safari is slowing down and the corresponding solutions to help you restore a smooth browsing experience.

Why does Safari slow down after macOS Sonoma update?

It is not uncommon for Safari to slow down after Sonoma update, but it needs to be resolved in time. First, we need to find out why. Safari can over-occupy system resources (such as memory), some extensions can also cause slowdowns, and even network connectivity issues can be the culprit.

The main reasons why Safari slows down under macOS Sonoma system:

1. Safari takes up a lot of system resources
2. Wi-Fi connection issues
3. Mac disk issues
4. Viral infection
5. VPN or security software issues

Next, we will analyze these reasons one by one.

Safari takes up a lot of system resources

Although Safari usually utilizes system resources efficiently, if you have frequent internet activity, the device may store unnecessary web history and data. The more tabs you open, the more memory you consume, causing your Mac to run slowly.

Wi-Fi connection issues

Sometimes, Safari runs slowly due to network connectivity issues. This includes Wi-Fi disconnection, inability to access the network, or inability to establish a Wi-Fi connection.

Mac disk issues

Mac disk errors can cause unexpected behavior in the device. Even useful applications such as Disk Utility can have a negative impact on the device. Therefore, Safari may run slower on macOS Sonoma due to formatting or disk structure issues.

Viral infection

Safari is a secure browser that detects and blocks a large number of viruses, but some viruses are cunning enough to avoid conventional detection methods. Any virus can seriously affect the performance of your browser.

VPN or security software issues

VPNs are very useful in protecting the privacy of web browsing. However, redirecting an internet connection via VPN takes time to encrypt data, limiting Safari's speed. You can try to switch the VPN server, disable the VPN connection, or use a shunt tunnel to resolve this issue.
