hi eduardosilva,
The path argument should be an existing directory, not including the file name. NeoRouter will create a new file for each session. You also need to make sure root:wheel has write access to it. To be simple, you can just put "Path=/usr/local/ZebraNetworkSystems/NeoRouter/".
NeoRouter client for Mac has two components, NeoRouter.app (the GUI app that user launches) and nrservice daemon (launches automatically and runs in the background). nrservice log will be most useful in debugging the issue.
After creating Log.ini, you need to restart nrservice. the easiest way is to "sudo killall nrservice" and OSX will recreate the nrservice process immediately, and nrservice will start writing to logs. If you are not familiar with commands, reboot the computer will work too.
Then please launch NeoRouter.app (the GUI client), retry signing in. When you reproduce the issue, exit NeoRouter.app, then "sudo killall nrservice". Now your should have a complete log file called "nrservice***.log". Send it to
support@neorouter.com.
Thanks,
Luke
