Has anyone upgraded to MacOS Mojave? Did it break anything in your dev environment?

It’s only been out a few days, but interested in hearing how everyone else has got on and whether anything development-wise broke :lol:


I’m updated my computers to Mojave. I haven’t had any real issues with Mojave as much as I have with XCode. I found a fix for it. This problem came across when compiling native extensions. A gem like mini_racer will fail to install.

Make sure XCode Command Line Tools is installed

xcode-select --install

Open the folder

open /Library/Developer/CommandLineTools/Packages/

Run the package macOS_SDK_headers_for_macOS_10.14.pkg

Then gem install mini_racer works!


I just performed upgrade today, to Mojave. It’s been the usual for me, making sure I use the opportunity to upgrade all my Mac apps, brew update && brew upgrade && brew cask upgrade, changing my passwords, the usual. Mostly uneventful. Definitely a lot more buttery smooth compared to High Sierra for me.

I had a problem only with the wifi in the offie, connecting but no internet.
The same problem has been experienced by 3 devs in my office.

Solved removed the files from the directory /Library/Preferences/SystemConfiguration/:

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

Everithing else was working eprfectly.
