Setup MacOS 10.14 Mojave Discussion

General • Asked by Chris Oliver


Is anyone else receiving errors with MacOS 10.14 Mojave and the Mysql2 gem? I'm also getting a "Library not loaded: libssl.1.0.0.dylib (LoadError)" error when executing "rails server".



Hey Ted,

If you upgraded, you probably need to uninstall the gem and reinstall it so that it compiles with the new Mojave libraries.

If you have trouble installing it from scratch, see this thread:


Yes, I have the same error.


what do you think about MacOS Mojave? Is it problematic? Have you got any other issues? I am wondering if it is better to upgrade now or to wait for a little bit.


I updated system to Mojave and generally i am happy. I had only one problem. My bluetooth didn't work in macOS Mojave. I have tried to clear the icon cache by starting your Mac in Safe Mode, then shut it down and restart it normally. It helped!
