A Mac that runs itself
Tahoe brought iPhone-style automations to the Mac — build three that save you time daily
👋 HEY, IT'S RAJA
Last week we turned Spotlight into a launcher. This week, we go one level deeper: getting your Mac to do things without you having to ask. macOS Tahoe quietly brought iPhone-style automations to the Mac — the kind that run themselves when a condition is met. Most people never open the app. Let's fix that.
📘 Set up a Mac that files, sorts, and switches modes for you
Tahoe added trigger-based automations to Shortcuts on Mac. Here's how to build three that quietly save you time every day.
What you'll need
- A Mac running macOS Tahoe (macOS 26)
- The Shortcuts app (already installed) and about 15 minutes
The big idea
Open Shortcuts, click Automation in the sidebar, and you'll see triggers that used to be iPhone-only: a specific time of day, when an app opens or closes, when a display or accessory connects, when a Focus mode turns on, at a certain battery level, or when a file is added to a folder. Each one can fire a shortcut automatically. Here are three worth building today.
Automation 1 — Work mode, the moment you plug in
Trigger: when my external display connects.
Action: turn on the Work Focus, open the three apps you always start with, and set Do Not Disturb.
Now your desk setup configures itself the second you dock. Build the reverse too — display disconnects, focus off — and your Mac relaxes when you undock.
Automation 2 — A downloads folder that files itself
Trigger: when a file is added to Downloads.
Action: sort by type — PDFs to Documents, images to a Screenshots folder, installers to Trash after a week. Even a simple version (just move PDFs) keeps your Downloads folder from becoming the digital junk drawer it always becomes.
Automation 3 — A wind-down that actually happens
Trigger: 10:30 PM.
Action: enable a Reading Focus, dim the display, quit Slack and Mail, and open your notes or journal app. The trick with wind-down routines is removing the decision — let the Mac start it, and you'll actually follow.
💡 Pro tip: Start with one automation, not all three. Live with it for a few days, tweak it, then add the next. Automations you don't trust get deleted; automations you barely notice are the ones that stick.
The result
Your Mac stops waiting for instructions and starts anticipating them. None of this needs a third-party app — it's all sitting in Shortcuts, free, right now.
That's it for today. See you Friday with five useful things.
Keep it useful,
