From the app, Mac OS, the download link on attachments to cards does not work.

[Dana Mark Pennie]

Client sends me copy and art on a Trello card. When I preview the attachment, the download link below the image is dead.

BTW, Some padding below that block of copy would also be nice.

Hi Dana,  sorry to hear that you aren't able to download attachments. This was a known issue on the old app version which is now been resolved. 
Please update the Trello desktop app to the newest version on the Mac App Store. It should then work great on the latest app version.

Kindly try this and let me know if the issue persists.
