Safari doesn’t auto play videos

ferreirex,

It's possible the specific website you're attempting to view has settings that stop the video from automatically loading. You can reach out to the web developer to find out for sure.

You can customize settings for specific websites in Preferences in Safari. The steps below will guide you through this so specific websites load the way you'd like them to.

1. "In the Safari app  on your Mac, choose Safari > Settings for This Website.
2. Choose the options you want for the website (options vary by website):

• Use Reader when available: View webpage articles without ads or other distractions.
• Enable content blockers: Stop ads and other unwanted content from appearing.
• Page Zoom: Make text and images easier to see.
• Auto-Play: Choose whether video can play automatically on the website.
• Pop-up Windows: Choose whether the website can show pop-up windows.
• Camera: Choose whether the website can use your camera.
• Microphone: Choose whether the website can use your microphone.
• Screen Sharing: Choose whether the website can use your camera and microphone.
• Location: Choose whether the website can know your location."

This information is from Customize settings for each website in Safari on Mac - Apple Support.

Take care.
