I think I've made some progress in identifying some of the causes of the failure of PAR packed apps to code sign on Mac OSX.
One thing in particular is that the code signature extends the length of the binary. It seems like the PAR executable has to end with "\nPAR\n". If I tamper with the binary in any way (e.g., add an extra character to the end of the file), PAR displays a default "Usage" message...e.g. [ -Alib.par ] [ -Idir ] [ -Mmodule ] [ src.par ] [ program.pl ]. The code signature needs to add characters at the end of this binary in order to be valid. Is there a way to have PAR ignore characters after this final \nPAR\n for packed executables? Thanks for your help all. I think this fix + Mach-O fixes to the header sizes will allow PAR apps to codesign, but still working on this. Will post a solution once available. Thank you, Dan
