Apple Mail seems to use its own location for downloading attachments that you double-click on. On my machine, this was in
~/Library/Containers/com.apple.mail/Data/Library/Mail\ Downloads
I wanted those to go into
~/Downloads
And since Apple as a company keeps thinking about even the illiterate, it hides the Library folder, and even if you unhide it for the Finder and create a “Shortcut”, it won’t work. So, open Terminal.app and do
mv ~/Library/Containers/com.apple.mail/Data/Library/Mail\ Downloads/* ~/Downloads rm -rf ~/Library/Containers/com.apple.mail/Data/Library/Mail\ Downloads ln -s ~/Downloads ~/Library/Containers/com.apple.mail/Data/Library/Mail\ Downloads
To fix that.
Interestingly, Apple Mail’s preferences did point to ~/Downloads all the time. But that’s used only when you do a “Save to Downloads Folder.”
Oh well…
