Actual behavior

python linting and code snippet are not working because of missing _clock_gettime on OSX 10.11. Is there any workaround not to upgrade High Sierra?

python plugin connect to language server and work well

Steps to reproduce:

1. Install the latest python plugin (2018.7.1)

Sorry, only OSX 10.12+ is supported as LS is in NET Core 2.0

Same as #2245

Is there any way to fix the problem without upgrading the OS?

@caimaoy @avence12 the fix is to stick with Jedi by setting "python.jediEnabled": true. We will also have code in the next release to help prevent people from trying to run the language server when they actually were never going to be able to.
