问题
My application runs fine on my system, and also on several others.
However, some people can't run the application because the file in /Contents/MacOS/ApplicationName is not a Unix executable file.
Inputting the following line in the terminal forces the application to be executable, and solves the problem:
chmod +x ApplicationName
Obviously this is a very hacky way around the problem, and I don't want to tell users to enter chmod to run my application. What am I doing wrong? Why is it appearing as a Unix executable file on some systems, but not others? It could be a permissions issue...
回答1:
at the moment, i transfer the app via dropbox to a client
Dropbox has problems with OS X metadata and permissions. Archive the application first (from the Finder context menu) and put the zip file into Dropbox.
