Give it a name

  • Continue until it prompts you for: “Specify a location for…”
  • Set Keychain location to System

Sign and entitle the gdb binary

Create a gdb-entitlement.xml file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">

codesign --entitlements gdb-entitlement.xml -fs gdb-cert $(which gdb)

Refresh the system’s certificates and code-signing data

Run sudo killall taskgated

Maybe you can reboot your computer!

Troubleshooting / further diagnosis

On 10.12 (Sierra) or later with SIP, you need to run this:

echo "set startup-with-shell off" >> ~/.gdbinit

Other commands

chmod 755 gdb
chgrp admin gdb
