open attachments in full screen in apple mail

Hi Bocamaz,

We're glad you're reaching out through Apple Support Communities for help with your attachments in Mail. We'd love to help sort this out.

So that we understand your issue or question, please let us know more about what's going on. What's the exact behavior you're seeing when attempting to open attachments in Mail on your Mac? Does this happen for all attachments?

Have you had an opportunity to quit the Mail app and reopen to test if any issues persist? How about restarting your Mac?

Have a great day!
