I recently got a Macbook pro 13 inch and I bought [this][1] docking station for all the ports I need. The issue is that my university network requires registration of mac id to use internet in campus and it's a cumbersome process. I already have a windows laptop that is registered so I wanted to change the mac id to start using my macbook. I followed [this][2] article to change my mac id, but I noticed two interfaces en1 and bridge0 have the same mac id, and I can only change mac id for bridge0 interface. Although changing mac id of bridge0 interface changes the mac id displayed in the advanced properties of Thunderbolt Bridge service in Network Preferences I still can't access internet. I am quite new to Mac OS and changing these stuff were quite simple in Windows, is there any way I can achieve what I want??
