After you have jumped through the initial screens from the Mac Setup Assistant that had you log in with your Apple ID, connect to a network and so on, your work is not done. Here are 10 settings to change or at least check on your new MacBook.
1. Check for updates
Has Apple released an update to MacOS Sierra since it built your MacBook? Find out by clicking the Apple button in the upper-left corner of your screen and then clicking About This Mac. You should be staring at the General tab of the About This Mac window. If so, click the Software Update button, which will launch the App Store app and check for updates.
2. Show battery percentage
Like an iPhone, a MacBook displays a small battery icon at the top of the display to show how much battery power remains. It's more helpful if next to this icon it also displays the percentage of battery you have left. To show the percentage, click the battery icon in the menu bar and click Show Percentage. (If you don't see a battery icon, go to System Preferences > Energy Saver and check the box for Show battery status in menu bar.)
3. Set up Siri
Siri should be enabled by default, but if you would prefer to use Siri only on your iPhone, then you can disable Siri by going to System Preferences > Siri and unchecking the box for Enable Siri. If you plan on using Siri frequently, then you can use this Siri window to choose Siri's voice, language and a keyboard shortcut.
4. Customize Touch Bar
If you have a new MacBook Pro model with the Touch Bar, then head to System Preferences > Keyboard and click the Customize Control Strip button and then simply drag the buttons you want to show up on the default view of the Touch Bar to the Touch Bar below the display. Don't worry, they'll make the leap from your display across the hinge and to the Touch Bar. (And please don't ask me why Apple calls it the Control Strip in some places and Touch Bar in others because I don't know.)
5. Sync folders via iCloud
I find it incredibly useful to sync the Desktop and Documents folders between my two Macs and my iOS devices. To sync these two folders, go to System Preferences > iCloud and click the Options button for iCloud Drive. Next, check the box for the top item, Desktop and Documents folders.
6. Choose default browser
Even though it uses more system resources than Safari, I use Chrome instead of Safari because the favicons help me keep track of all of my open tabs. To set a default browser, go to System Preferences > General and make a selection other than Safari for Default web browser.
7. Set scrolling direction
A MacBook's "natural" scrolling direction doesn't feel natural to me. If you want the two-finger swipe gesture to scroll vertically in the opposite way, head to System Preferences > Trackpad and click on the Scroll & Zoom tab. Next, uncheck the box for Scroll direction: Natural.
8. Get your Dashboard
MacOS Sierra lets you juggle multiple desktops via Mission Control, which you can swipe through using the three- or four-finger swipe gesture. The Dashboard is a special desktop that lets you pin various apps to it for quick access to current weather conditions, your calendar, a calculator and other info. To enable the Dashboard, go to System Preferences > Mission Control and change the Dashboard setting from Off to either As Space or As Overlay. The former sets up the Dashboard as your leftmost desktop, and the latter overlays it on your current desktop with the press of the F12 key.
9. Add and remove items from Dock
Apple throws a number of stock apps into the Dock at the bottom of the screen. You can make room for the apps you use most frequently by removing others you don't need in the Dock. To remove an app from the Dock, simple click on its icon in the Dock and drag it to the desktop until you see Remove appear above the icon and then let go. Poof, it's gone! To add an app to the Dock, open it and then right-click on its icon in the Dock and mouse over the Option line in the menu and click Keep in Dock.
10. Move the Dock
The Dock sits at the bottom of your screen, but on a widescreen MacBook display, you might find it better to have it on the side. To move the Dock, go to System Preferences > Dock and choose either Left or Right for Position on Screen. While you're there, you can also drag a slider to adjust the size of the Dock. You can also make it disappear from view when you aren't using it by checking the box for Automatically hide and show the Dock.
