Hi, the current AppBundler version doesn't support setting the CFBundleVersion. When I look at the source code (AppBundleTask) I see that the CFBundleVersion is set to "1" writeProperty(xout, "CFBundleVersion", "1"); If you like to submit an app to the MacAppStore you'll have to set the correct app version (CFBundleVersion) Best regards, Tobi
