1/ How to Enable Type to Siri in macOS High Sierra — Just like in iOS 11, you can enable Type to Siri in macOS High Sierra. This is a feature that lets you type queries to Siri, just like you would a search engine. It’s useful for people who may feel awkward talking to their iPhone or Mac. It’s also helpful in certain situations where silence is a virtue, like in a library. Here’s how to turn in on in macOS.
Open System Preferences, then go to Accessibility. Scroll to the bottom and click on Siri in the left sidebar. You’ll see a checkbox that lets you turn on Type to Siri.
Next, go back into System Preferences and click on the Siri icon. You can enable or disable voice feedback, should you wish.
2/ Check a flight status using Spotlight — High Sierra has made it easier to check the status of a current or upcoming flight. Click on Spotlight’s magnifying-glass icon in the upper-right corner of your screen or press Spotlight’s keyboard shortcut (Command-Spacebar). Now type in the airline and flight number into the search bar that’ll appear.
If you end up with multiple results in the left-hand list, click through them to find the particular flight you’re looking for (and get more information on it).
You can also tell you have got than one result by the little pips at the bottom of the right-hand pane. This indicates you could swipe to view each of the results in turn if you’d rather do that than click them.
3/ Stop videos from auto-playing in Safari — Open Safari and go to Safari>Preferences. Click on the Websites tab, then select Auto-Play from the sidebar. Within this list, you’ll see the websites you currently have open and ones you’ve previously configured auto-play settings for (if any), both with drop-downs next to them:
Allow All Auto-Play – all videos on the site can autoplay.
Stop Media with Sound – only videos that don’t have audio will autoplay.
Never Auto-Play – no videos can autoplay.
Finally, there’s a drop-down at the bottom of that window that’ll allow you to change the global setting.
By default, Safari should stop all media with sound, but if you’d like to be a bit more heavy-handed, you could switch this to Never Auto-Play. Yes!
4/ Set up Custom Reminders — You set a reminder for yourself that repeats on Monday, Wednesday, and Friday, or configure one that pops up on the first weekend day of every month, whenever that happens to fall.
Open the Reminders app and click on a blank line to type in the title of your item. Hover your cursor over your new reminder afterward, and you should see a small ‘i’. Click that and you’ll see the options for how you’ll be reminded. To set up a custom repeat, select On a Day, and then click next to the Repeat section. A drop-down menu will offer you a Custom choice. Set a frequency for your repeated reminder: daily, weekly, monthly or yearly. Every frequency type has its own options; for example, weekly lets you pick multiple days of the week on which to get your notifications.
You can do the same thing with Monthly or use the drop-down menus at the bottom to get reminded on, say, the first weekend day of every month. Just click Done to commit.

5/ Use ‘Grep’ to Find Matching Lines — This one’s a bit more pointy-headed. The Terminal doesn’t care if you know what you’re doing, which is why it’s always a great idea to be careful what you type in it! But one command that’s simple to use (at least at its most basic level) is grep. You can use grep to pull lines that contain search terms out of a text file. Here’s how it works: Let’s pretend this text file of mine has many hundreds of lines of data that I need to paw through.
Terminal lives in your Applications>Utilities folder. It gives you a prompt to start (ending with a dollar sign) – type ‘grep test’ (without the the single quotes).
Now you have to tell Terminal which file to run things on. An easy way to do this is by making sure to type a space after your search term, and then drag and drop the file you want to search onto the Terminal window. The program will fill in the path to the file for you,.
If you then press Return on your keyboard, the Terminal window will fill up with the lines that match your search.
