rsync replaced with openrsync on macOS Sequoia
by from OpenBSD Journal on (#6WFFZ)
We (undeadly.org editors) had not noticed ourselves, but Will Backman wrote in about the news that some OpenBSD code -- openrsync -- had been made available to a wider audience, courtesy of Apple:
"While Apple has been updating the rsync 2.6.9 command line tool it shipped with macOS as needed in response to security issues and other problems, the fact remains that Apple's version of rsync up until macOS Sequoia was almost twenty years old and did not include any of the new features introduced in rsync versions which came after version 2.6.9."
"Now with macOS Sequoia, Apple has replaced rsync 2.6.9 with openrsync, an implementation of rsync which is not using any version of the GPL open source license."

The editors can confirm that on a fully updated Mac, man rsync will reveal that rsync is indeed the OpenBSD openrsync.
