How do I clear my Safari cache?
Open Safari.
In the menu bar at the top, click on Safari and select Preferences.
Click on the Advanced tab.
Check the box that says Show Develop menu in menu bar (this will enable the Develop menu if it isn’t already visible).
Close the Preferences window.
In the menu bar, click Develop, then select Empty Caches.
Alternatively, you can clear your browsing history and cache at once:
In Safari, go to History in the menu bar.
Select Clear History.
Choose the time range (e.g., the last hour, today, today and yesterday, or all history).
Click Clear History.
This will clear your history, cookies, and cache.
