How to Fix Safari Page Not Responding in macOS Tahoe 26.2
Safari on macOS Tahoe can sometimes "freeze" even on simple sites, showing the spinning beachball of death.
The full fix is in The Fix section below. Verified on macOS Tahoe 26.2.
Recommended Troubleshooting Tool
Before proceeding with manual fixes, we recommend using CleanMyMac X. Excellent for clearing Safari caches, bloated databases, and stuck background processes.
The Symptom
A website loads partially, then becomes unresponsive. You might see a "This webpage is using significant memory" warning.
The Fix
- Clear the Website Cache
Go to Safari > Settings > Privacy > Manage Website Data... and click "Remove All."
- Disable Experimental Features
Tahoe often ships with experimental features enabled.
Go to Safari > Settings > Advanced.
Check "Show features for web developers."
In the new Develop menu, go to Feature Flags and click "Reset All to Defaults."
- Purge the Safari Cache via Terminal
Quit Safari and run:
rm -rf ~/Library/Caches/com.apple.Safari
rm -rf ~/Library/Safari/LocalStorage/*.localstorage
Pro Tip
If only one specific site is crashing, try opening it in a Private Window (Cmd+Shift+N). If it works there, an extension is likely the culprit.
