MacVoices #18204: David Sparks Releases Field Guides On Siri Shortcuts and OmniFocus* David Sparks has released not one but two brand new Field Guides to help make you a “digital ninja”. In the Siri Shortcuts Field Guide, David doesn’t just show you how to use the latest Apple productivity tool, but lets you download his example shortcuts so you can modify them to suit your own needs, not a bit of code required. Then, David delivers his personal productivity spin in the OmniFocus Field Guide to help you build a working task management system that you will understand and will work for you. He also talks about his transition to video-only training, his site, and how sharks with lasers figures into it all.
