How to open a stubborn email attachment in Mail on your Mac

This message indicates something is wrong with the Mail Downloads folder’s permissions.

Mail has stymied some people after they upgrade macOS and try to open attachments. Instead of the attachment opening in the appropriate application, an app claims “you don’t have permission to view it” or “access to file name was denied.” However, if you drag the file out of Mail onto the Desktop or into another Finder window, you find you can open it without any error.

If you’re running macOS 11 Big Sur, make sure you have installed the 11.6.7 update released June 9, 2022, which fixes some attachment problems in Mail.

If you’re using a different version of macOS or that Big Sur update didn’t fix your problem, the solution may be as simple as fixing permissions on the deeply nested folder that Mail uses to hold attachments. Here’s how to proceed:

In the Finder, choose Go > Go To Folder.Paste in the following: ~/Library/Containers/ the folder Mail Downloads.Choose File > Get Info.Under Sharing & Permissions, you should see name (Me) and Read & Write next to it. If you do not, click the lock in the lower-right corner of the Get Info window and authenticate as requested by macOS.

Then perform one of the following actions in the Get Info window’s Sharing & Permissions section:

Click the popup under Privilege next to the name (Me) entry and choose Read & Write.If your name doesn’t appear in the Name column, click the + (plus) sign, choose your name, and click Select. Then select Read & Write in the Privilege column to its right.Now click the circled more button (… in a circle) at the bottom, choose Apply to Enclosed Items and click OK to confirm.

Use Get Info to examine permissions for the folder (left) and then fix them.

This should solve the permissions issue for most people. If that doesn’t work, I recommend restarting into macOS Recovery and running Disk Utility’s Disk First Aid as described in these steps.

If that still doesn’t solve the Mail attachments problem, I suggest a non-destructive reinstallation of macOS in place. Make sure you create a full Time Machine or similar backup before reinstalling macOS.
