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.

How

Wi-Fi recommendations are available in macOS Sierra or later.

Analyze your wireless environment

Your Mac can use Wireless Diagnostics to perform additional analysis.

  1. Quit any apps that are open, and connect to your Wi-Fi network, if possible.
  2. Press and hold Option (Alt) ⌥ key, then choose Open Wireless Diagnostics from the Wi-Fi status menu .
  3. 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.

Mac Virus Finder

  • 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:

Virus
  • Info gathers key details about your current network connections.
  • 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.

Additional recommendations for best Wi-Fi performance:

  • Keep your router up to date. For AirPort Time Capsule, AirPort Extreme, or AirPort Express Base Station, check for the latest firmware using AirPort Utility. For non-Apple routers, check the manufacturer's website.
  • Set up your router using Apple's recommended settings, and make sure that all Wi–Fi routers on the same network use similar settings. If you're using a dual-band Wi-Fi router, make sure that both bands use the same network name.
  • Learn about potential sources of Wi-Fi and Bluetooth interference.

Macs don’t get viruses, right? Wrong, sadly. Your Mac may be safer from malware than the average Windows PC, thanks to its Unix core and Apple’s default security settings in the OS, but it’s not immune. All it takes is one thoughtless click on a link in an email or on a website, and your Mac could be infected.

The good news is that performing a Mac virus scan is very easy and if it finds anything, getting rid of the virus is very straightforward, too.

How to check your Mac for a virus

There are a number of tell-tale signs that your Mac has a virus. If it’s not displaying any of those, there’s probably nothing to worry about. So, before you scan your Mac for a virus, here are a few things to check.

1. Is your Mac behaving erratically?

This could include applications crashing, web browsers loading pages you didn’t ask for, and unusually high traffic on your network.

2. Has it started running very slowly all of a sudden?

Some viruses run processes that hog CPU cycles and leave little capacity for the tasks you want to carry out.

3. Are you seeing adverts or pop-ups for things you would never normally see?

Adware viruses are designed specifically to show adverts in the hope that you’ll click on them.
4. Have you noticed software appear on your Mac that you didn’t deliberately install?

Some viruses appear in the form of browser extensions, others run in the background, but some may appear as applications in your Applications folder. Before we'll explain how to scan Mac for malware, check these 5 tell-tale signs.

If any of the above are true, it’s possible that your Mac has a virus, but don’t panic, it may be relatively easy to remove.

How to run a malware scanner on Mac

So how to check for malware on Mac? There are several Mac virus scanners that allow you to scan your system. However, it’s very important that you don’t just google ‘free Mac antivirus software.’ Many sites that claim to offer free antivirus tools in fact host viruses themselves. So, you go to the site looking for a solution and end up making the problem worse. It’s important to use a reputable tool. We recommend using CleanMyMac X.

CleanMyMac X detects thousands of malware threats, including adware, spyware, worms, ransomware, cryptocurrency miners, and if it finds something suspicious, it offers immediate removal. Here’s how to scan your Mac for malware:

  1. Download CleanMyMac X (free edition here) and launch the app.
  2. Click on the Malware Removal tab.
  3. Click Scan.
  4. Click Remove.

Malware Monitor is another thing I love about CleanMyMac X. And this Mac malware scanner works in real-time. Whenever an adware attempts to enter some protected areas on your Mac, you’ll get instantly notified.

How to get rid of suspicious apps

If you find an application that you didn’t intend to install, you should get rid of it. But don’t just drag it from your Applications folder to the Trash, that won’t remove every trace of it from your Mac. Applications store files in a number of different places in your Mac’s Library folders. You could hunt them down and remove them manually, but it’s quicker and easier to use a dedicated uninstaller like CleanMyMac X. That way, you can be sure you will remove every trace of the application and no stray files will be left behind.

  1. Download CleanMyMac for free here.
  2. Launch it from your Applications folder.
  3. In the Utilities section, click on Uninstaller.
  4. Look through the list of applications until you see the one you want to get rid of.
  5. Check the box next to it.
  6. Press the Uninstall button.

How to prevent your Mac from getting a virus

Scanning Mac for malware is one thing. But prevention is always better than cure. So, if you want to make sure that every virus scan returns a clean bill of health, here’s what to do.

  1. Never click a link in an email unless you’re 100% sure where the email has come from and where the link will take you. Reputable companies and banks won’t ask you to click a link to log into an account, for example.
  2. Never download anything unless you’re certain what it is. That includes movie files, software updates, games, and anything else you’re not absolutely certain about.
  3. Keep your Mac updated with the latest version of macOS. That doesn’t mean you have to be running the very latest OS, but if you’re running, say, Sierra, make sure you install the latest updates when they become available.
Mac

Scanning your Mac for threats is very easy. To check Mac for malware, you can download the free version of CleanMyMac X which is an Apple notarized app. With its help, you get rid of any applications you didn’t intend to download and scan your whole system for malware very quick and easy. Give it a go.
