This week in "Apple did something weird with XCode..."

OS Version: Mac OS X 10.11.6

Looks like _getentropy was added in 10.12, and Tor automatically picked it up. That is strange: we build with -mmacosx-version-min=10.7, which should hide newer symbols.

Investigating further. Workarounds are to update to Sierra, replace Ricochet.app/Contents/MacOS/tor with another tor binary and make codesign stop screaming, or remove that file and put a tor in $PATH (and maybe also make codesign stop screaming).

Awesome, to help others with the workaround:

1. Install Homebrew and get it setup / updated
2. brew install tor
3. Then in a new terminal window (or after running rehash to detect new tor binary):

cd /Applications/Ricochet.app/Contents/MacOS
rm -f tor
ln -s $(which tor)

Works like a charm. Oddly enough there was no complaint when I launched it via the Dock again... even though I have GateKeeper set to allow only from Mac App Store and identified developers... Perhaps because I already launched it once? (Is this a security bug in OS X that I just discovered?)

macOS SDK bug: <sys/random.h> is supposed to have an __OSX_AVAILABLE_STARTING macro for getentropy.

This is going to require patching tor in the build, which is something I prefer to avoid, but.. :/

Rebuilt with that patch. Please give this a try and let me know if it works:

Hey that worked, thanks! 😄

Great! I updated the GitHub release and website with the new link. Should be solved now. Thanks!
