How troubling the loss of these scripting languages will be depends on who you are. Who is affected, and what are their options?
#Shebang node js mac brew install#
Maintaining these languages has not been one of Apple’s the company has not kept current with updates to the languages, and users can’t easily use standard tools to find and install additional libraries from the vast repositories available. That’s not a lot in the scheme of things, but it’s also not trivial with an operating system that has to be downloaded millions of times.įinally, there’s a principle that in business, you should focus on your strengths. macOS comes with thousands of these library files that total over 150 MB. The runtime programs for each are small, but like all programming languages, they have many code libraries, common tasks script writers can call upon so they don’t have to reinvent a particular wheel. Removing scripting languages will also make macOS use less disk space. Gatekeeper prevents the automatic running of applications from unknown developers, but scripts are just text files that can do a great deal when executed by the scripting language runtime.

These languages are common in Unix-based systems and have been in Mac OS X since 2001, so why remove them now? Apple has progressively changed macOS to make it more secure, and that is likely the company’s primary motivation for this change. Three reasons: security, efficiency, and focus. Why remove these scripting languages at all? But that won’t become clear for at least a year, and in the meantime, we’ll all have to ponder the implications if Apple does kick these languages to the curb.

So this may all be a tempest in a teapot if Apple doesn’t end up following through on this threat. For instance, when Apple introduced launchd in Mac OS X 10.4 Tiger, it deprecated the venerable cron scheduling system ten macOS versions later and cron is still humming along, available for users. However, Apple has at times deprecated longstanding components without removing them entirely. The most absolute interpretation is to assume that Apple means “ future versions” after Catalina won’t include the runtimes necessary to execute scripts written in these scripting languages.

If your software depends on scripting languages, it’s recommended that you bundle the runtime within the app.

Future versions of macOS won’t include scripting language runtimes by default, and might require you to install additional packages.

Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. The first macOS 10.15 Beta Release Notes has a Deprecations section that says: When Apple announces major new versions of macOS, the company often includes details not just about the next release but also about what will come further in the future.
