Has anyone tried Grid Cartographer 4 on the latest macOS update 'Sierra' ? Does it work ? Problem areas in the past have been the file selectors and custom tiles so I'd be especially interested to know whether those still work.
I will probably update my Mac to this version and make Sierra support official in v4.0.3, for now it's not officially supported - but I know a lot of people will have upgraded already anyway.
