-### No Sidecar Injected in GKE private clusters
+## DNS is broken on macOS
+
+Commands like `dig` cannot find cluster resources even though Telepresence is connected to the cluster, but it works
+with `curl`.
+
+This is because `dig`, and some other utilities on macOS have their own built-in DNS client which bypasses the macOS
+native DNS system and use the libc resolver directly. Here's an excerpt from the `dig` command's man-page:
+> Mac OS X NOTICE
+> 
+> The nslookup command does not use the host name and address resolution or the DNS query routing
+> mechanisms used by other processes running on Mac OS X.  The results of name or address queries
+> printed by nslookup may differ from those found by other processes that use the Mac OS X native
+> name and address resolution mechanisms.  The results of DNS queries may also differ from queries
+> that use the Mac OS X DNS routing library.
+
+A command that should always work is:
+```console
+$ dscacheutil -q host -a name <name to resolve>
+```
