Click the System Preferences icon on the Dock and choose Network.
It's best to set up your Mac somewhere that has a Wi-Fi network or other connection to the Internet. Your Mac will use that connection to complete certain setup steps. If the network requires a password, have the password ready.
Plug in only the essential devices
If you're using an external keyboard and trackpad or mouse, turn them on or plug them into your Mac. If you're using an external display, plug it in and turn it on as well, but don't connect any other peripherals yet. And of course plug in your Mac.
If you've never used a trackpad before, here's a tip: To click, press down or tap on the trackpad surface.
Turn on your Mac
Some Mac notebooks automatically start up when you connect the computer to power or open its lid. On other Mac computers, press the power button to start up.
Use the setup assistant
A series of windows will ask you for setup details, such as your Apple ID. If you've used iTunes or have an iPhone or iPad, you already have an Apple ID. Use the same Apple ID on your Mac.
We recommend that you let the setup assistant turn on FileVault, iCloud Keychain, and Find My Mac. You can also let it transfer information from another computer or Time Machine backup, or you can do that later using Migration Assistant.
You'll be asked to create the name and password of your computer account. You'll need this information to log in to your Mac, change certain settings, and install software.
Check for software updates
When the setup assistant finishes setting up your Mac, you'll see the Finder, which includes a menu bar at the top of the screen and the desktop below that.
Click App Store in the Dock at the bottom of your screen, then find and install any software updates. After your software is up to date, you can connect any printers or other peripherals and begin using your Mac.
If you've followed the steps to connect your Mac to a Wi-Fi network, but the connection to your network or the Internet isn't reliable, the steps in this article might help.
Check for Wi-Fi recommendations
When your Mac tries to connect to a Wi-Fi network, it checks for issues that affect its ability to create a fast, stable, and secure connection. If an issue is detected, the Wi-Fi status menu in the menu bar shows a new item: Wi-Fi Recommendations. Choose it to see recommended solutions.
Wi-Fi recommendations are available in macOS Sierra or later.
Analyze your wireless environment
Mac Usb Wifi Adapter
Your Mac can use Wireless Diagnostics to perform additional analysis.
- Quit any apps that are open, and connect to your Wi-Fi network, if possible.
- Press and hold Option (Alt) ⌥ key, then choose Open Wireless Diagnostics from the Wi-Fi status menu .
- Enter your administrator name and password when prompted.
Wireless Diagnostics begins analyzing your wireless environment:
If the issue is intermittent, you can choose to monitor your Wi-Fi connection:
When you're ready to see recommendations, continue to the summary. Wireless Diagnostics asks for optional information about your base station or other router, so that it can include that in the report it saves to your Mac.
Click the info button next to each item in the summary to see details about that item. Wi-Fi best practices are tips that apply to most Wi-Fi networks.
Back up or make note of your network or router settings before changing them based on these recommendations—in case you need to use those settings again.
Monitor your Wi-Fi connection
Your Mac can monitor your Wi-Fi connection for intermittent issues, such as dropped connections. Follow the steps to analyze your wireless environment, but choose ”Monitor my Wi-Fi connection” when prompted.
During monitoring, a window shows that monitoring is in progress. Monitoring continues as long as this window is open and you're on the same Wi-Fi network, even when your Mac is asleep.
If Wireless Diagnostics finds an issue, it stops monitoring and shows a brief description of the issue. You can then resume monitoring or continue to the summary for details and recommendations.
Create a diagnostics report
Wireless Diagnostics automatically saves a diagnostics report before it displays its summary. You can create the same report at any time: press and hold the Option key, then choose Create Diagnostics Report from the Wi-Fi status menu . It can take your Mac several minutes to create the report.
- macOS Sierra and later saves the report to the /var/tmp folder of your startup drive, then opens that folder for you.
To open the folder manually, choose Go > Go to Folder from the Finder menu bar, then enter /var/tmp. - OS X El Capitan or earlier saves the report to your desktop.
The report is a compressed file with a name that begins “WirelessDiagnostics.” It contains many files that describe your wireless environment in detail. A network specialist can examine them for further analysis.

Use other diagnostics utilities
Wireless Diagnostics includes additional utilities for network specialists. Open them from the Window menu in the Wireless Diagnostics menu bar:

- Logs enables background logging for Wi-Fi and other system components. The result is saved to a .log file in the diagnostics report location on your Mac. Logging continues even when you quit the app or restart your Mac, so remember to disable logging when you're done.
- Scan finds Wi-Fi routers in your environment and gathers key details about them.
- Performance uses live graphs to show the performance of your Wi-Fi connection:
- Rate shows the transmit rate over time in megabits per second.
- Quality shows the signal-to-noise ratio over time. When the quality is too low, your device disconnects from the Wi-Fi router. Factors that affect quality include the distance between your device and the router, and objects such as walls that impede the signal from your router. Learn more.
- Signal shows both signal (RSSI) and noise measurements over time. You want RSSI to be high and noise to be low, so the bigger the gap between RSSI and noise, the better.
- Sniffer captures traffic on your Wi-Fi connection, which can be useful when diagnosing a reproducible issue. Select a channel and width, then click Start to begin capturing traffic on that channel. When you click Stop, a .wcap file is saved to the diagnostics report location on your Mac.
