# Work around for some odd behaviour where we can't codesign a file
|
|
# in-place if it has been called before. This happens for example if
|
|
# you try to fix-up a binary using strip/install_name_tool, after it
|
|
# had been used previous. The solution is to copy the binary (with
|
|
# the corrupted signature from strip/install_name_tool) to some
|
|
# location, sign it there and move it back into place.
|
|
#
|
|
# This does not appear to happen with the codesign tool that ships
|
|
# with recent macOS BigSur installs on M1 arm64 machines. However it
|
|
# had also been happening with the tools that shipped with the DTKs.
