Beginning with macOS 10.12 Sierra, you must manually move Direct Mail from the downloads folder before software updates can be installed. Here is how to move Direct Mail to your Applications folder:
Quit the Direct Mail app by choosing Direct Mail > Quit Direct Mail from the menu bar at the top of your screen
Switch to the Finder app by clicking its icon in the dock
Locate the Direct Mail app in your downloads folder (or wherever you saved your copy of the Direct Mail app)
Drag the Direct Mail app and drop it onto the "Applications" icon on the left-hand side of the window
Switch to the Applications folder by clicking on the "Applications" icon on the left-hand side of the window
- Double-click the Direct Mail icon to relaunch Direct Mail
After you relaunch Direct Mail, it will begin the software update process again.
If you can't find where the Direct Mail app is located on your Mac
When you download Direct Mail from our website, it is (by default) saved to your Downloads folder. If you can't seem to find it there, however, there are a couple ways you can locate it:
In the Finder, choose File > Find from the menu bar at the top of your screen and search for "Direct Mail"
If the Direct Mail app is currently running, hold down the command key on your keyboard and click on the Direct Mail icon in the Dock. A popup menu will appear. Choose Options > Show in Finder from that popup menu.
