#26 Mac OS Sierra with Display Ethernet

[John Moreci]

Hi - just some feedback. I was able to successfully use Basilisk (Mac emulator) with tuntaposx to talk to a Real Mac Plus via AppleTalk. I was running a MacBook Pro running Mac OS El Capitan with an ethernet cable directly connected to the laptop. I tried the same on a newer MacBook Pro running Mac OS Sierra that does not have an ethernet port but is connected to a display with an ethernet port. I was not successful with this set-up. Not sure if it is an issue with Mac OS Sierra or using the display ethernet (en3 in my case).

i figured out what i needed to do. Below are the steps:

For use with Display Internet it is necessary to create a new virtual interface.

1. Install TUNTAP as directed by emaculation basillisk II appletalkCreate a Bridge virtual network interface https://support.apple.com/kb/PH18510?locale=en_US
2. Follow steps 3 - 6 if the laptop does not have a direct ethernet connection (e.g. uses Display Internet). Otherwise go directly to step 7.
3. Open Network (System Preferences —> Network
4. Select “Manage Virtual Interfaces” from Gear Icon below the list of connections
5. Create New Bridge with name TunTAP with Display Ethernet as the included Interface. It doesn’t matter what name use choose. Note the BSD Name, it should read something like bridgeX where X is and number (e.g. 0, 1, 2, etc.)
6. Hit Done. This will disconnect the computer from the ethernet interface
7. Configure Basilisk following the emaculation link above. Go to the Serial/Network tab and enter at Ethernet Interface and enter “etherhelper/tap0/bridgeX/enY” using X = 0 if you did not need to create a bridge or the value from step 5 above if you did. Use Y as appropriate for your ethernet connection. You can determine this by using the “ifconfig” command in terminal.
8. Start Basilisk II
9. Check to see if the bridge and tap0 are active by opening terminal and entering command “ifconfig.” You should see “tap0” appear in the listing before “bridgeX” and you see that “tap0” listed as a member under “bridgeX”
