David Sparks is moving all of his content from Vimeo and iBooks to his own Teachable site. If you haven't checked out the mac tips series that I did with him, you can find [60 Mac Tips Volume 1](https://learn.macsparky.com/p/60tipsv1) and [Volume 2](https://learn.macsparky.com/p/60tips2) on the new site, along with his guides for Hazel, Workflow, and more.
