I have always used Aperture and always will while it still works. However my big worry is upgrading my camera. I already know several people who have upgraded to Canon 6D MkII and 5D MkIVs and are annoyed that they are not supported even though High Sierra supports these cameras. An Aperture plugin to support new cameras would be grately appreciated by everyone who uses Aperture and still see it as a superior raw converter to Lightroom. I have purchased Raw Power for Mac OS and iOS and plan on testing it out in the near future but would really like an Aperture plugin version.
