Attachment to Email Stuck Downloading

Hi, what I have found out is the following. It seems the file "OpenedAttachmentsV2.plist" is the problem.

Shut down your Mail program and then if you remove that file from the next location you will be fine:

Open Finder;

Open menu Go;

Click and hold the Command button and you will see the Library option in that menu;

Now the finder screen opens in your Library folder;

Open the folder "Mail";

Then look for the folder that starts with V (V6 in my situation -> Mojave 10.14.3)

In this folder you will find the file "OpenedAttachmentsV2.plist", delete that file.

Now restart your mail and your attachments will open just fine.

I believe they meant for you to hold down the Option button > the Go menu should then reveal the User library (which is what you want, not the System library).

After that, follow the path shown in my screenshot (your version may be different, I'm on an older OS). My "openedattachment" file is from back in 2015. Normally, .plists are regenerated automatically. However, I've never touched that one, so I'd suggest you move it to your desktop (do not delete or empty trash yet). After moving it, restart your Mac. Test to see if it now works. Test to make sure the .plist has regenerated itself. If all that is good, then delete the old one. If it doesn't, put the old one back.

And, if none of that works, the attachment may be too large. Go your email service in a browser window, sign into your account, and either download and/or delete that attachment while there.

Could be - is this from a) someone you trust and b) can that person tell you what the file is supposed to be? Could be and innocent forwarding of an attachment containing malware.

If you can't delete the attachment, can you delete the entire email online? I'd get rid of the whole thing and tell the sender that you are unable to download it.

There is you answer.

FWIW, I used to use Onyx occasionally (note the emphasis is on "used to"); today's Mac OS is becoming a walled garden with a lot of security features built in and no access to system files, so that type of app has run its course in my humble opinion. I'd also question a report of 94 malware items, all part of OSX.

This doesn't work for me still stuck with "downloading"

Not sure what is going on, but your link results in an ampty black page on my iPad.

Are you sceptical about Onyx? I have used Onyx for a decade. Working fine. The thing is that Onyx shows if you have files that might have malware. Onyx is a free app and you do not have to go to AppStore to get it. I don't. Onyx do pick up the attachment Mail don't want to download. Just proving why I don't get the attachments, not solving the actual problem.
