Configuring XAMPP on macOS Sierra (version 10.12.6)

On a fresh installation of macOS, I decided to use XAMPP (I have previously used MAMP (free ver.)) but I have encountered some simple issues. 1. The general tab shows IP address 192.168.64.2 but my system IP is 192.168.1.100. Why is the IP different by default? And how can this be changed to use the same? The "go to application page" loads dashboard on 192.168.64.2 but I'd like to use the localhost on some port like localhost:8888 / 127.0.0.1:8888. 2. Trying to open phpmyadmin returned an access forbidden page ("... New XAMPP security concept: ..."). I looked up about it in google which showed results suggesting to edit the configuration file to allow external access. I'd like to keep it to localhost, so I guess the IP has to be changed to localhost. How can that be achieved? 3. Unlike MAMP, there is no option to set the port within the application, so I tried to look for the httpd file in `Applications->XAMPP->(show package contents)->contents->... but did not find the file. So where are the configuration files? > P.S. Do not suggest to turn off the system provided apache server > (sudo apachectl stop)
