Subject: [Pythonmac-SIG] ctypes, codesigning, notarizing, py2app?
Message-ID: <D0D98D73-F3A6-47A4-B43D-7D87C86F8F20@gmail.com>

Hello,

I?m trying to codesign and notarize my application, and thanks to the following thread I?m getting closer:

https://mail.python.org/pipermail/pythonmac-sig/2018-October/024341.html

However, I?m stuck there, since my app _does_ require ctypes.

Is there currently a way to use ctypes in a py2app-built application, and have it codesigned and notarized? I?m afraid the answer may be ?no?, if I read the thread correctly...

Thanks for any clues,

Just

I?ve found a solution. Adding the following entitlement during codesigning allows me to use ctypes:

   com.apple.security.cs.disable-executable-page-protection

That is a big relief.
