Before everyone goes off and do their own thing thinking everything is fine and dandy.. this version disables OpenGL!! So Maps etc won't work (which is fine).. but AND it subsequently it will log a console message twice a second!! Something like this: WindowServer[119]: _CGXGLDisplayContextForDisplayDevice: No matching context for device (0x7fe3a1d1ad60) - disabling OpenGL So best to do is select WindowServer and click Ignore Sender on the toolbar.. it is not the best solution but it saves some CPU cycles. I have filed a bug report -> under Help -> Report a problem
