Little by little we are seeing more news of the first beta of OS X El Capitan and one of them is that mDNSresponder is officially on the Mac operating system. Apple you do not want problems in network administration and management and choose mDNSResponder.
In the beta 4 of the current OS X Yosemite, Apple already introduced the change from discoveryd to mDNSResponder and seeing that it is reporting fewer problems they have opted for add it from the beginning in the new software presented last Monday.
The truth is that it is a "step back" because mDNSResponder it was used in old versions of OS X and Apple replaced it with discoveryd to improve this connectivity and network management. In the end it turned out to cause more problems than benefits (some users with many problems in WiFi connections) and therefore they bet on what worked well for them in their day.
We continue to see the news of this OS X El Capitan beta 1 and we are going to discuss them during these days with all of you. The truth is that we observe something of higher performance in general of the operating system but news in terms of interface there is not much to say. This time the Cupertino have preferred to improve the performance of OS X with some improvements in terms of productivity and not touch anything visual except the renewed font on all devices.
