Mac users now have a window snapping feature built directly into macOS Sierra, which allows users to easily snap windows to aspects of the screen or against one another. This offers a nice way to quickly and precisely align windows, and it's more or less the Mac equivalent feature of window snapping from the Microsoft Windows world.
Window snapping on the Mac will snap windows to any of the following targets: edges of other windows, the menu bar, the top of the Dock (if visible), and the sides of the screen.
With several windows open on the Mac display, grab one and drag it against a snap target. You'll "feel" the dragged window snap to place, repeat with additional windows as desired
The window snapping ability in macOS is a bit more full featured than what is offered in the Windows world, with a broader range of snap targets. You can snap however many windows together that you can fit on screen, regardless of their size.
While you can't completely turn off window snapping, you can temporarily disable window snapping in macOS with a keystroke action when moving windows around on the screen. To temporarily disable window snapping, hold down the Option (alt) key when you're dragging and moving windows around.
Most Mac users have a clock and some other small icons in the upper right corner of their screen. Apple calls these Menu Extras but Mac users generally refer to them as menulets. What many people have not learned is that those menulets can be repositioned, deleted and customized.
Simply hold down the Command key and your mouse button and drag a menulet to a new position. The other Menu Extras will scoot out of the way as you drag. Release the mouse button to drop the menulet in its new position.
Removing is the same process as moving, with the exception of you drag downward and release the mouse. On release, a poof of smoke animation will appear, to let you know you have removed the item.
Apple provides Mac users with over two dozen handy menulets. Go to your startup disk and select System > Library > CoreServices > Menu Extras. The menulet names should give you an indication of their intended function. Double clicking a menulet will automatically add that menulet to the main menu.
Your Mac is pretty safe on your private home network, but what about when you're surfing the Web in coffee shops? Anyone with a computer and rudimentary hacking skills could target you, which is why it's important to make sure your Mac's built-in firewall is enabled and that stealth mode is turned on.
macOS's firewall feature blocks unwanted network traffic coming into your computer, and stealth mode makes your Mac essentially invisible to hackers snooping for computers to target. They aren't foolproof features, but they will keep most people from finding and attacking your Mac on public networks.
First, you need to make sure your Mac's firewall is enabled:
• Go to Apple menu > System Preferences.
• Choose Security & Privacy.
• Select the Firewall tab.
• If the firewall is active you’ll see a green dot and "Firewall: On." If not, click Turn Firewall On. You may have to click the padlock icon and authenticate with your Mac's password to change the setting.
Next, enable stealth mode:
• Click Firewall Options. It's below the button for turning the firewall on and off.
• Check Enable stealth mode.
• Click OK.
"Automatically allow built-in software to receive incoming connections" and "Automatically allow downloaded signed software to receive incoming connections" should already be checked. Those settings let the apps you already have communicate through the firewall without you having to take any extra steps. Leave those checked unless you know what you're doing and plan to manage app network access manually. You should leave "Block all incoming connections" unchecked too, unless all you're doing is surfing the Web.
Despite the promise long ago of the paperless office, we still need to print documents from our Macs at times. The usual launch an app to print a document routine works fine for that, but you can save a little time by printing your files directly from the Finder.
Printing a document without first launching the app that created it is easy. Just select the document and use the Command-P keyboard shortcut (or go the the File menu and choose Print). The default app for the file's format will launch, and in most cases will send the document to your default printer without any interaction.
Applications that expect more user input before printing, like professional design apps, will wait for you to configure your print settings before putting ink on paper. It adds back in an extra step, but for file formats that default to Preview, it's as simple as select-and-print.
