What is Mac’s wireless diagnostics?

Mac’s wireless diagnostics is what it sounds like—it’s Apple’s diagnosis of the reasons for your Wi-Fi issues. Also known as Mac network diagnostics, the wireless diagnostics tool is like Mac’s Apple diagnostics, but for Wi-Fi connection issues.


You can prompt Mac to “diagnose” the issue when you have trouble connecting to Wi-Fi. The issues you may experience typically include slow connections while doing any of the following:

  • Loading internet pages
  • Loading emails
  • Streaming music or video.

Mac does better at getting to the bottom of it than we could ever do. That’s because, although we may troubleshoot the root cause of these issues, we would most likely be grasping at straws.


Not only does Mac’s wireless diagnostics find the root issues by performing analysis, but it provides solutions to fix the problems, too. It also gives you a guide on best practices when using Wi-Fi on your Mac.


As a result, you’ll be able to speed up your Mac’s slow internet and start browsing the internet without hassle again.
