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.
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.
Your Mac can use Wireless Diagnostics to perform additional analysis.
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.
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.
On a Mac without an eject key (like the MacBook Air or the MacBook Pro from 2012 forward), you can force your computer to shut down at any point by pushing Command + Control + Option + Power button.You can find the Power button on the top right corner of the keyboard or Touch Bar. If your Mac won’t shut down, press and hold the power button for 6 seconds to force a shutdown. Important: If you force a shutdown, you may lose unsaved changes in open documents. A Mac is completely shut down when there is a black screen; some computers also don’t show an active power light or have any fan or drive noise. Shutdown.exe is the process responsible for System Shutdown and Restart. Normal Shutdown is the term we’ve used here to mention the default Shutdown. Force Shutdown will stop all processes and forcefully shuts down your PC. Force Shutdown with time set as a parameter, will force shutdown your PC at the specified time. Force shutdown for mac.
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.
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.
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.
Wireless Diagnostics includes additional utilities for network specialists. Open them from the Window menu in the Wireless Diagnostics menu bar:
