1/ Siri by default — If you keep forgetting that Siri is now in your Mac, to encourage yourself to use Siri consider changing the keyboard shortcut that launches it to Command + Space. This is usually the keyboard shortcut for Spotlight – then you can change Spotlight’s keyboard shortcut to Option-Space, or something.
Why? Whenever muscle memory presses the shortcut that used to summon Spotlight, Siri appears instead and forces you to find the file, open the application, perform the Web search, or whatever using your voice instead of the keyboard.
You can change Siri’s shortcut in System Preferences>Siri, and the one for Spotlight in System Preferences>Spotlight.
2/ Need some more reasons to give Siri a go? Siri is brilliant at maths: complex equations, Pi, conversions of anything to anything, percentages … it’s so much easier than launching apps and tapping keys and all that palaver.
3/ Get your system specs — The information available under Apple Menu>About This Mac has been vastly improved, but now we have another way to figure out machine specs in macOS Sierra: Siri. Apple’s voice assistant can answer all sorts of questions for you or for anyone you’re trying to help, like ‘How much memory is on my Mac?’ ‘How much free storage do I have on my Mac?’ and ‘How fast is my Mac?’
Click on the Siri icon in the upper-right corner of your screen or hold down the key-combo, and start talking.
4/ What’s the weather like? Siri will respond to a variety of weather-related queries, from the standard “What’s the weather forecast for today?” to more conversational requests, such as “Will it rain today?” Yussss!
5/ Your system can recommend how to save storage space — If you’re running out of space on your Mac, Sierra’s has suggestions for you. The latest version of macOS makes recommendations based on your current usage of your drive.
Click on the Apple Menu at the upper-left corner of your screen and choose About This Mac. Now click the Storage tab, and from there, pick Manage. When the next window pops up, select Recommendations in the sidebar, and you’ll see what your Mac thinks you need to do. This might suggest setting the trash to empty every 30 days, automatically removing iTunes media after you’ve watched it etc. When you click on the button next to one of the recommendations, your Mac will walk you through turning it on and will mention any caveats.
Be sure your machine has a backup before you make any big changes like these, especially if you’re going to turn on iCloud Photo Library and sync your images with your other Apple devices.
If the Recommendations feature is asking you to do something you don’t understand (especially if you’re using the Reduce Clutter option to review your files), then consider putting the brakes on. Better to keep extra files on your Mac than to remove something you need(although, of course, you really should have a backup).
