It must be a dead project. There doesn't seem to be any way to make it work. I setup a Flickr and Google filter, with a saved download path, and nothing I do will get it to work. Nothing ever shows up in the download folder, and nothing happens other than errors in the console that it's cant access the path to itself; "universalAccessAuthWarn: AccessibilityAPI: pid 49866, is not allowed to access the accessibility API. Path: /Applications/Wally.app/Contents/MacOS/Wally"
also some other error; "Wally: WARNING: The Gestalt selector gestaltSystemVersion is returning 10.9.6 instead of 10.11.6. This is not a bug in Gestalt -- it is a documented limitation. Use NSProcessInfo's operatingSystemVersion property to get correct system version number.
and other garbage. Basically, it doesn't work at all, and there's no support at the authors site. If you go there for support, all it does is say that you are not allowed to post, so useless in every possible way. Big waste of time.
