Q: Updated to EL Capitan 10.11.6 broken my Ethernet!
Hello,
I just upgraded my 2 x NewMacPro 2013 to El Capitan10.11.6. But the Ethernet was not working after updated...It was same situation as “Incompatible Kernel Extension Configuration Data 3.28.1” Event " If the Ethernet connection on your Mac stopped working recently - Apple Support "....
It only happened in NMP, older Mac Pro 2011 upgrade to 10.11.6 is fine.
Who can help me to solve this problem??
Thank you,
Interface.
Mac Pro, OS X El Capitan (10.11.6)
