Q: How to flush DNS cache OS X 10.10.4?
I used "sudo discoveryutil mdnsflushcache", but terminal told me that "sudo: discoveryutil: command not found", which is kinda odd, coz I've been using this command for quite a few months.
I just updated my OS X to 10.10.4, maybe that's why it's not working?
Apple's official support page about this hasn't been changed for months.
MacBook Pro with Retina display, OS X Yosemite (10.10.4)

Apple has changed back to the older DNS responder:

Try using the older command for Mavericks:
