+@noindent
+The Darwin Kernel requires the debugger to have special permissions
+before it is allowed to control other processes. These permissions
+are granted by codesigning the GDB executable. Without these
+permissions, the debugger will report error messages such as:
+
+@smallexample
+Starting program: /x/y/foo
+Unable to find Mach task port for process-id 28885: (os/kern) failure (0x5).
+ (please check gdb is codesigned - see taskgated(8))
+@end smallexample
+
+Codesigning requires a certificate.  The following procedure explains
+how to create one:
+
+@itemize @bullet
+@item Start the Keychain Access application (in
+/Applications/Utilities/Keychain Access.app)
+
+@item Select the Keychain Access -> Certificate Assistant ->
+Create a Certificate... menu
+
+@item Then:
+
+@itemize @bullet
+@item Choose a name for the new certificate (this procedure will use
+"gdb-cert" as an example)
+
+@item Set "Identity Type" to "Self Signed Root"
+
+@item Set "Certificate Type" to "Code Signing"
+
+@item Activate the "Let me override defaults" option
+
+@end itemize
+
+@item Click several times on "Continue" until the "Specify a Location
+For The Certificate" screen appears, then set "Keychain" to "System"
+
+@item Click on "Continue" until the certificate is created
+
+@item Finally, in the view, double-click on the new certificate,
+and set "When using this certificate" to "Always Trust"
+
+@item Exit the Keychain Access application and restart the computer
+(this is unfortunately required)
+
+@end itemize
+
+Once a certificate has been created, the debugger can be codesigned
+as follow. In a Terminal, run the following command...
+
+@smallexample
+codesign -f -s  "gdb-cert"  <gnat_install_prefix>/bin/gdb
+@end smallexample
+
+... where "gdb-cert" should be replaced by the actual certificate
+name chosen above, and <gnat_install_prefix> should be replaced by
+the location where you installed GNAT.
