I have a similar problem to the above thread; this time using a MacBook Pro (15-inch, 2016) again with the thunderbolt adaptor. My device is available on the thunderbolt Bus and there is a 1 in the kext database. However, both the app and OSX cannot access the network interface. Looking in system information extensions page shows the SanLink2 Device but not as loaded. I have tried telling the terminal to load the SanLink2; it does load but still no network cards visible in OSX or in the Sanlink utility.
Any help greatly appreciated.
Output from Terminal - "/KextPolicy '.dump kext_policy' | grep promise
INSERT INTO kext_policy VALUES('268CCUR4WN','com.promise.SANLink-FC',1,'Promise Technology Mobile Apps',1);"
