1/ Change the default search scope in the macOS Sierra Finder — The macOS Sierra Finder is the home base for your Mac. You use it to organize and access almost everything on your Mac, including documents, images, movies, and any other files you have. When you do a search, the Finder will search through your entire Mac to find what you’re looking for. However, you can change the default search scope:
In the Finder (i.e., then the word to the right of the Apple icon at top left is ‘Finder’ – this is where you tell what the ‘foremost’ app or program is on a Mac), click on this Finder menu and select Preferences from the drop-down menu.
Click the Advanced tab.
Navigate to the bottom of the Preferences window and locate the drop-down menu labeled ‘When performing a search’ and click on it.
You’ll have three options from which to chooses: Search This Mac, Search the Current Folder and Use the Previous Search Scope. Pick the one you want.
2/ Hidden Display options — Displays on Mac just get better and better, but Apple has simplified the interface that drives them in macOS 10.12 Sierra and the Detect Displays button now appears to be missing. The option in System Preferences>Displays is still there, and there are others, revealed a simple keystroke: it appears when you hold down the Option key on your keyboard, the Detect Displays button replaces the Gather Windows button at lower right – this is handy if your Mac has somehow ‘lost’ one of your attached monitors or projectors.
Another feature you can take advantage of lies in setting the resolution for your display. With the Scaled option selected, you’ll see quite a few native resolutions for your monitor and graphics chip. However, if you press the Option key as you click the Scaled radio button, you’ll see even more resolutions for you to pick from if you have a non-Apple secondary monitor plugged in (it does not work for built in displays, at least not in my case). But be careful with the resolution choices, as some of them might not be native to your display or Mac. That means they might not work out for you, even though they’re listed.
3/ Connect a USB printer in macOS Sierra — The default printer is the one selected when the Print dialog opens. If ‘No printer selected’ shows up instead in the Print dialogue, you’ll need to add a new printer.
For most USB-connected printers, all you have to do is update your software then connect the printer to your Mac. macOS can automatically detect the printer and download any necessary software. But for other printers, you may have to complete a few steps to add the printer. Here’s how.
Update your software: choose Apple menu > App Store, click Updates, then install any software updates listed. Even if no updates appear, this ensures that macOS has the latest information about printer software it can download from Apple. If you don’t do this, you may see a message that software isn’t available when you connect your printer.
Prepare your printer: use the instructions that came with your printer to unpack the printer, install ink or toner, and add paper. Turn on the printer and make sure it’s not displaying any errors.
Connect your printer: connect the USB cable to your Mac. If you see a message prompting you to download new software, make sure to download and install it.
Important: If your Mac has a single USB-C port, use a multiport adapter. Connect the printer, then connect a USB-C cable to a power supply to prolong the battery life of your Mac.
Go to System Preferences, and choose Printers & Scanners.
If a printer appears in the list, you can click on it. If none appears, click the “+” icon To remove a printer, click the “-“ icon. [From Apple World Today.]
4/ Always start new iWork documents with a specific template — Pages, Numbers and Keynote just got free updates with lots of new features, so why not have them work more usefully for you on first launch? If you prefer to always start with a blank document, or if you regularly use one particular template, you can configure Pages to start out with that selection instead of the Template Chooser. This also works with Numbers and Keynote, by the way. Here’s how to configure the app to start new documents the way you want.
By default, this is what you see when you opt to create a new document in Pages
This configuration setting is located within the Preferences menu in Pages for macOS. Just click Pages in the upper left corner of the menu bar, then choose Preferences from the drop-down menu.
You’ll probably notice that the top option from the General pane, Show Template Chooser, is selected beside For New Documents. Below that, you’ll see an option labeled Use template. Click the radio button to select that choice. When you select Use template, it will probably automatically choose the Blank document. If that’s what you want, exit the Preferences pane. If you want to use a different template, click on Change Template.
Now, a new window will open to allow you to choose your default template. Scroll through, make your selection, and then click Choose. Now, every time you open a new document in Pages (or Numbers or Keynote, as you can change those preferences, too) it will begin with the template you selected. If you regularly create documents from a particular template, or always generate your files from scratch, setting this option will save you a mouse click or two.
5/ Prevent Photos and iTunes from opening automatically on Macs when you plug in an iPhone or iPad — When you plug an iDevice into your Mac, you might have noticed that iTunes and Photos open. If you’re looking to sync music over to your device or import pictures, that’s great; however, if all you want to do is charge the device while you’re at your computer, then having to quit a couple of pesky programs is less awesome.
Both applications have a way to disable this behaviour, though. Start by plugging in the device, and then if necessary, click on the small icon in the toolbar [shown at left] to access its settings.
When that next screen appears, look under the “Summary” tab to find “Automatically sync when this [device] is connected” (which may instead say “Open iTunes when this [device] is connected”).
Uncheck that box and click ‘Apply’ in the bottom-right corner.
Photos’ option is just as easy to find. Plug in your iPhone or iPad as before, and then depending on your configuration, you may have to either click on the “Import” tab at the top, or choose the device itself from your sidebar. Then you should see a little checkbox near the top-left of the window labeled Open Photos for this device.
Uncheck that, and you’re all done – when you plug in that iPhone or iPad now, neither program will open.
