Installing a new macOS can provide users with plenty of exciting functions and features. Still, upgrades are often followed by unexpected performance issues. With Sonoma, a frequent complaint is that Safari runs too slowly.
Does it discourage you from updating your computer to the latest macOS version? It could, especially if you're used to a fast browsing experience. However, all is not lost—one way to solve this irritating problem is to clean up your Apple device’s storage.
In this article you will find the following:

Why is Safari so slow after macOS Sonoma update
If Safari is slow after Sonoma is updated, it actually isn’t a common thing but a problem to be fixed. Try to find out the reason why first. Sometimes, Safari may exploit system resources like memory. Also, some extensions may slow your browser down. Even your internet connection may be the root of the issue.
Though Safari is quite efficient in system resource usage, your device can end up storing unnecessary web history and data, especially if your activity levels are high. The more tabs you open, the more memory is consumed by Safari, which results in your Mac being very slow.
Wi-Fi connection issues
Sometimes, Safari runs slowly on Mac Sonoma because of the internet, so you have to know how to fix a slow internet connection. The other core causes of this are Wi-Fi disconnection issues, an inability to access the network, or a complete failure to establish a Wi-Fi connection.
Mac disk problems
Mac disk errors cause unexpected behavior in your device. Even a helpful app like Disk Utility, which is one of the most resourceful Mac tools, can negatively impact your device. Hence, due to problems related to the formatting or disk structure, Safari can result in running slowly on Mac Sonoma.
Viruses
Safari is a secure browser used to detect and block plenty of viruses, but some of them are smart enough to avoid typical methods of discovery. Moreover, any virus is a real threat that could impact a browser’s performance.
Problems with VPN or security software
VPN is our friend when we need to protect privacy while browsing the network. However, redirecting your internet connection through a VPN takes some time to encrypt your data, constricting the speed of your Safari. Nevertheless, you can solve such problems by switching VPN servers, disabling your VPN connection, or using split tunneling.
How to speed up Safari on macOS Sonoma
Now that you're aware of the reasons for Safari being slow, our experts are ready to provide you with our list of solutions to speed up Safari on Mac Sonoma:
1. Check the quality and speed of your internet connection

See the following info to learn the details behind your internet connection:
Packets in, Packets out: that’s the total number of received and sent packets;
Packets in/sec, Packets out/sec: here’s the speed of information transfer in packets per second;
Data received, Data sent: by this, you’ll see the amount of information moved in megabytes;
Data received/sec, Data sent/sec: consider the amount of information moved over time in bytes per second.
2. Restart your MacBook
Another easy way to speed up Safari is to restart your MacBook. Doing so can clear up temporary files, install updates that are on standby, and close all active apps. All these things give your browser a fresh start. Here’s how:
