Affects - QuarkXPress Server 2015 on Mac OS 10.10.x/10.11.x


The behavior of host name resolution on Mac OS 10.10.x/10.11.x is different than other OS due to IPV6 lookup. There is a configurable parameter in to change “localhost” to “” at post installation of QuarkXPress Server on Mac OS 10.10.x/10.11.x for users who notice this delay issue. There is no functional impact of making this change.


The root cause of the delay issue is with the resolution of host name “localhost” on Mac 10.10.x and 10.11.x. As per the default hosts file, resolving of “localhost” is through IPV6 (from ::1 entry of hosts file) which takes more time and then try to connect although IPV6 is inactive.


  1. Quit QuarkXPress server or Stop its service.
  2. Navigate to
    Mac HDD//Applications//QuarkXPress Server 2015//conf/
  3. Change the value of a property “qxpswebserver.ip” in from “localhost” to “” as shown below.
  4. Now, Start QuarkXPress Server. After this change, the output will be faster.
