The cache part starts with - Cache - and ends with a summary like Cache currently contains 391 entities 33 referenced by active questions.
Roughly the first half of the output in Console with the time stamp noted previously is the DNS cache. To check your DNS cache open Console.app (enter mDNSResponder in the Search field) and Terminal.app.Ĭheck the time and enter in Terminal: sudo killall -INFO mDNSResponder Please use the short tt (the name of your volume) instead of my long tt-this_. With a real HDD/SSD you can expect even faster responses. So the time needed to resolve it is less than ~0.071/2 ms. The average round-trip time is ~0.071 ms. tt-this_is_a_VM_disk_and_therefore_slower_than_a_real_disk ping statistics -ģ packets transmitted, 3 packets received, 0.0% packet loss Now you can check the response time by pinging it: ping tt-this_is_a_VM_disk_and_therefore_slower_than_a_real_disk To properly and quickly name resolve your hard disk/SSD, you also have to add its name to the hosts file: 127.0.0.1 localhost santas-macbook-pro-2.local tt-this_is_a_VM_volume_and_therefore_slower_than_a_real_disk You are mixing a lot of completely or partly different/unrelated things here. What on earth do I have to do to get this machine to forget about being Santa's MacBook Pro? It seems discoveryutil doesn't exist any more (in any case it's not on my machine), so I can't even look at the contents of the cache. I've tried flushing the DNS cache following the instructions here, restarted, and I still get Santa's MacBook Pro.local returned. In running the little inetTester I get Santa's MacBook Pro.local returned. Got OnyX to flush various caches including system and kernel extensions, restarted, still slow.
How to clear mac cache el capitan trial#
Tried renaming the computer and hostname to trial and trial.local (updating etc/hosts accordingly) and the hard disk to tt. I tried editing the etc/hosts file as follows: 127.0.0.1 localhost santas-macbook-pro-2.localīut even after a restart the resolution was still as slow as ever. (I didn't choose to put the "-2" at the end of the hostname that's what the Mac had in the Sharing preference pane.)
How to clear mac cache el capitan pro#
My computer name, hostname and hard disk names used to be as follows: Santa's MacBook Pro I'm trying to get my El Capitan's (10.11.6) DNS cache to flush, to try and solve slow localhost domain name resolution, but nothing I do has any effect.
