Hi, I would like to thank a lot Matt. Sorry to not reply before, but I would be sure of the solution. I did two points to sign my application: First point, as you mentioned Matt, I removed "--deep" parameter, but that wasn't sufficient for my issue. Second point I used your format for my entitlement file. To be more accurate, my new entitlement file is : <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.cs.allow-jit</key> <true/> <key>com.apple.security.cs.allow-unsigned-executable-memory</key> <true/> </dict> </plist> With this two points my application runs !! Thanks a lot Matt for your quick and good answer.
