In trying to push our second app to the Mac App Store; I'm getting a new warning about a missing "LSHandlerRank" in my document types.
So in trying to get my apps through Apple's excruciating App Review process, I've modify App Wrapper to add this option. Download the latest beta of App Wrapper 3.9.1 (if your version is older than the date of this article) from
If you need to re-new your upgrade plan, take a look at the http://www.omegabundle.net/ and score $2,700 worth of developer tools for as little as $349.
Open your application in App Wrapper, then navigate to the "Info" pane. Under the "Document Types" click on the "+" button and add all the document types that your application supports. There's a new column which reads "Rank", click in each cell of this column and select an option. There are helptags for each option to help you decide which one is most appropriate. Save, wrap and enjoy.
This is very much a beta version as I've made some significant changes to the final stages in attempts to find some clues as to why the Notarized DMG files are being rejected on Catalina.
