Because of crbug.com/222934, you cannot rely on gl_version for macosx.
For osx you can only use os version, and vendor/device ids.
So you have to split your new entry into 2. First one for the
general case that will apply on all os except osx.
Second entry will be specific to macosx, see below for example:

                     // this is what other osx entries do in this file
    }
