Derring-Do

MacBook Pro 15 inch, mid 2009 (macbookpro5,3), OSX El Capitan 10.11.3 Just to add my two cents worth to this thread on Mac OSX and the Tetra, I have got everything working following advice from this forum. The Realtek driver (link here) is a bit tricky but once the most up-to-date is installed, things seem to work well. ZTerm, although dated, works well and allows serial connection (second micro usb labelled UART), if that type of control is needed. Internet sharing is easy with the Sharing tab in system preferences. I selected sharing the WiFi with the USB 10/100 LAN and added the following commands to a script to enable El Capitan to play nicely. defaults write /Library/Preferences/SystemConfiguration/com.apple.nat NAT -dict-add SharingNetworkNumberStart 172.16.42.42 defaults write /Library/Preferences/SystemConfiguration/com.apple.nat NAT -dict-add SharingNetworkNumberEnd 172.16.42.200 defaults write /Library/Preferences/SystemConfiguration/com.apple.nat NAT -dict-add SharingNetworkMask 255.255.255.0 Great device. I am very happy with my Tetra.
