Mattias Lasu commented on LOG4NET-535:
--------------------------------------
I expected to be able to write loggings to the syslog but now the syslog in
Sierra have changed to Unified Logging. I do not know if that should be a new
appender or not.
Error description:
I get an exception when I try to call syslog(…) in method Append(…) in file
LocalSyslogAppender.cs.
It fails because something goes wrong when calling syslog method and DllImport
for libc.
I get this exception when trying to call syslog and dllimport:

> Affects Versions: 1.2.15, 2.0.6
> Environment: macOS Sierra osx 10.12 and 10.12.1

> LocalSyslogAppender doesn’t work on macOS Sierra 10.12
> New logging in macOS Sierra osx 10.12, unified logging:
> "Unified logging is available in iOS 10.0 and later, macOS 10.12 and later,
> tvOS 10.0 and later, and watchOS 3.0 and later, and supersedes ASL (Apple
> System Logger) and the Syslog APIs. Historically, log messages were written
> to specific locations on disk, such as /etc/system.log. The unified logging
> system stores messages in memory and in a data store, rather than writing to
> text-based log files."
