Mail prevented some people from upgrading to MacOS and trying to open attachments. Instead of opening attachments to the appropriate application, an app claims “you do not have permission to view it” or “access to it” File name Was denied. “However, if you drag the file from Mail to the desktop or another Finder window, you can open it without any errors.
The solution can be as simple as fixing permissions in a deeply nested folder that uses to hold mail attachments. Here’s how to proceed:
In Finder, select Go to> Folders.
Paste the following: ~/Library/Containers/com.apple.mail/Data/Library/
Select the Mail Downloads folder.
To like File> Get info.
Under Sharing and Permission, you must see Name (I) and read and 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 Sharing and Permissions section of the info window:
Click on the popup next to Privilege Name (I) Entry and selection Read and write.
If your name does not appear in the Name column, click the + (plus) sign, choose your name, and click Select. Then select Read and write In the Privilege column on the right.
Now click on the more circle button below (in that one circle), select Apply to bound items And click All right To confirm.
This should solve the permission problem for most people. If that doesn’t work, I recommend restarting macOS recovery and running Disk First Aid of Disk Utility as described in these steps.
If this still doesn’t resolve the mail attachment issue, I recommend reinstalling a non-destructive MacOS. Make sure you have a full time machine or similar backup before reinstalling macOS.
