How to watch the log-file so that it is updated realtime in the viewer?

Question

macOS

Tell me, please, what program can be used to view the log file (located on hdd) so that they display all changes in real time, without pressing the "Update" or "Reload file from disk" buttons?
The question is relevant only for MacOS (Mavericks) and Windows (7).
Thank you!
