If You Properly Installed macOS High Sierra and Still Have Slow WiFi Try These Fixes

Did we get you excited about High Sierra?

High Sierra ditches Apple’s historic file system and uses a new system creatively known as the Apple File System (APFS). The are also small updates to Notes and support for external virtual reality headsets and graphics-processing units.

The bulk of macOS High Sierra’s noticeable updates are in Safari. One of the most welcome changes is that Safari will mute any autoplaying videos. As you’re browsing, you’ll no longer be assaulted by a blaring advertisement or YouTube show. In the update, Safari will also limit websites’ abilities to track your browsing history. This will limit the amount of data that advertisers can gather on you. A small change, but any advances in privacy are certainly welcome!

If you upload, organize, and view photos in Apple Photos, you’ll love the redesigned space. Apple is giving the application a new layout with a power boosted sorting tool. Further, the app will have increased facial recognition power and access to more editing tools (such as curves!). High Sierra makes an already great tool for iPhone and MacBook users even better.

And did you follow our four must-dos before installing macOS High Sierra?

If you still have slow wifi:

You probably need to update your WiFi preferences. To do that, you just have to remove your current preferences. Click on any empty spot on the Desktop and hold down Command + Shift + G.

Type this in the directory that pops up: /Library/Preferences/SystemConfiguration/

In the folder that opened, delete these files:

  • com.apple.airport.preferences.plist
  • com.apple.network.identification.plist
  • com.apple.wifi.message-tracer.plist
  • NetworkInterfaces.plist
  • preferences.plist

After these files are gone, reboot your Mac and reboot your WiFi router.
