Fix Keychain, TrustD Crash

If process "trustd" is using 100% (or any large amount) of CPU...

This is usually caused by a damaged system keychain.
Delete /Library/Keychains/system.keychain.
Restart computer.

Note 1: This causes saved passwords, certificates, etc to be lost, so use with caution.
Note 2: Optionally, open keychain first and make a note of any important passwords.
Note 3: Only applies to system keychain, which should not contain your passwords.
