with v16.5 I am encouraged and upgrade to high sierra, now I can not connect to the lan. thunderbold deactivated, dhcp does not assign me ip.
Does someone know how to solve this problem ?
Sounds like the upgrade isn't complete. Are you on 10.13.3? Thunderbolt shouldn't enter into it unless you were using an adapter to connect to Ethernet. Is this an office or home network? Have you tried WiFi, and at a different location? Is this just connecting with FileMaker, or any network? If you have everything backed up, boot into recovery mode, erase the drive and reinstall.
Ok,...the solution is :
-> Select Ethernet
-> gear( config.)
-> manage virtual interfacez
-> click gateway thunderbolt (bridge0)
-> click ethernet thunderbolt
Glad you were able to get it resolved. Have a better day.
