Agile Web Development with Rails 7.2: Replace "OS X" reference with "macOS" (Page 10)
fishburn
Like “MacOS” references, any general references to macOS in its most recent versions should be “macOS”. Specific references to past OS versions, like “OS X Lion”, of course, should remain unchanged.
The middle of page 17 has another reference (“On OS X, you need to install the developer tools”). And the bottom of page 133 has one (“some OS X users can use Console.app…”).
