I’m running macOS 27 Golden Gate RC and tried to update one of my Enhanced Applets. I wondered why I can’t drop files into the droplet window anymore; an older version still works fine under macOS 27. So I looked into the Bundle & Export Settings and found this strange behavior options:
It should look like this:
I can’t fix it in any way. The fields are merged again when you apply the changes or, at the latest, during compilation. Manually tinkering with Info.plist won’t help, because it invalidates the signature.
My current solution is to validate the file types in the appletFileIsAcceptable handler:
property allowedExtensions : {"png", "svg", "psd", "tiff", "tif", "gif", "pdf", "jpg", "jpeg", "icns", "heic", "heif", "bmp"}
on appletFileIsAcceptable(theFile)
if folder of (info for theFile) is true then return false
return name extension of (info for theFile) is in allowedExtensions
end appletFileIsAcceptable
Maybe there is a better solution.
