**Network Adapter Malfunction: The built-in WiFi adapter may be defective. Consult with Apple Support or a certified technician for diagnosis and potential repair or replacement.
WiFi Router Problems: To check if the issue lies with the router, try connecting another device to the WiFi network. If other devices can connect, the router may be working fine, and the problem resides with the Mac.
Restoring WiFi Functionality
If you’ve reached this point and still can’t connect to WiFi, try the following final steps before seeking professional assistance.
Step 10: Reinstall macOS
As a last resort, consider reinstalling macOS. This should be done only if all previous solutions have failed:

What are common signs of WiFi issues on a Mac Pro?
The most common signs of WiFi issues on a Mac Pro include intermittent connectivity, slow internet speeds, and inability to connect to the WiFi network altogether. Users may experience frequent disconnections or find that their device cannot detect available networks. Other signs include the WiFi icon showing as “No Service” or “Disconnected.”
Additionally, if webpages take a long time to load or streaming services frequently buffer, these can also indicate WiFi problems. Checking the WiFi signal strength in the menu bar can help diagnose the issue further; a weak signal suggests potential connectivity problems that need addressing.
How can I restart my Mac Pro’s WiFi connection?
Restarting your Mac Pro’s WiFi connection is a straightforward process. First, click on the WiFi icon in the menu bar and select “Turn Wi-Fi Off.” Wait a few seconds, then click the icon again and select “Turn Wi-Fi On.” This simple procedure can often resolve temporary connectivity problems.
If issues persist, you might want to consider rebooting your Mac Pro altogether. To do this, go to the top left corner, click on the Apple menu, and select “Restart.” This can refresh all system processes and may help to rectify ongoing WiFi issues.
What should I check if my Mac Pro won’t connect to WiFi?
If your Mac Pro won’t connect to WiFi, start by verifying that your WiFi network is running and accessible. Check other devices to see if they can connect to the same network. Ensure that airplane mode is disabled, and consider rebooting your router to resolve any potential issues. If the router appears to be functioning correctly, proceed with troubleshooting your Mac Pro.
Next, check your WiFi settings on the Mac Pro. Go to System Preferences and select “Network.” Ensure that WiFi is selected and check if it’s turned on. If your network isn’t listed, click “Join Other Network” and manually enter the details. Make sure you have the correct password entered, as an incorrect password can also prevent connections.
How can I reset the SMC on my Mac Pro to fix WiFi issues?
Resetting the System Management Controller (SMC) on your Mac Pro can sometimes resolve hardware-related issues, including WiFi connectivity problems. To reset the SMC, first shut down your Mac Pro. Once it’s off, unplug the power cord, wait for at least 15 seconds, then plug it back in. Wait an additional 5 seconds before turning your Mac Pro back on.
This process can help clear any temporary settings that could be impacting performance. Remember that resetting the SMC affects hardware settings, so it’s a good idea to note any specific configurations you may have changed prior to the reset.
What can I do if my WiFi connection is slow on my Mac Pro?
If you’re experiencing a slow WiFi connection on your Mac Pro, first assess your internet speed using a speed test tool. This can determine if the problem lies with your internet service provider (ISP) or your local setup. If speeds are significantly below expected levels, try rebooting the modem and router to clear any network congestion.
Another potential issue is network interference or weak signal strength. Check your WiFi environment for obstructions or other devices that may interfere with the signal, such as microwaves or cordless phones. If possible, try moving closer to the router or using a wired connection to improve speeds.
