You might have had the same problem I just did: I tried to create a global hotkey shortcut command situation for popping up a new mail message. I’m trying hard to only look at my inbox Xx/day, but I often have emails I need to send. So, I tried to create a global shortcut using Automator on my OSX Mac. The tutorials all said to open Automator, create a new Service with no input from any application, drag the New Mail Message or whatever over to the workflow, save it, and then go find it under the “General” tab in System Preferences -> Keyboard -> Shortcuts -> Services -> General. Unfortunately, that General section on the right of Services didn’t appear.
Here’s why: you need to save your Automator Workflow Service in ~/Library/Services. I went and looked in that folder, and found that my workflow wasn’t being saved there. Turns out when I was saving the workflow automatically in iCloud instead.
See the save location? Go to wherever you’re saving that workflow and drop it into your user/Library/Services folder.
