Thanks Tim This got me further down the line, I now know that the problem is "resource fork, Finder information, or similar detritus not allowed"
However, I have no idea how to prevent 4D from adding such detritus to the built app! Following the link in the tech note, I executed "xattr -cr <pathtoapp>" and tried to sign it again. This time I got the message "<pathtoapp>: code object is not signed at all In subcomponent:<pathtoapp>/Contents/MacOS/HelperTool" Can anyone help me unpick this? Thanks!
