Apple don't keep their scripting languages updated. For example, macOS Mojave 10.14.6 ships with perl 5, version 18, subversion 4 (v5.18.4) in /usr/bin/perl; but my homebrew setup provides perl 5, version 30, subversion 0 (v5.30.0).
(And for those who don't know perl, it's been semi-permanently pinned at "perl 5" as a major version number for about 20 years due to the existence of perl 6, which is effectively a different language—as different as C++ is from C—so those minor version number differences are as significant as a major version number change in another language.)
While this doesn't bother me much per se, the issue I see as looming is what I've experienced on a few platforms. Where their "protection" mechanisms effectively prevent you from building the code you need to function effectively.
I usually test each (new) platform by taking my code and trying to build it. If the platform is important to what I do, I'll spend some time making sure it builds correctly, and passes regression testing.
WSL in Windows 10, albeit running on a kvm on my linux laptop, does not pass muster as a system worth targeting for a number of reasons. Not the least of which is that the environment breaks the regression testing.
My concern is that MacOS gets to that point. Its getting close, as I have to specifically allow perl/python/julia/jupyter to open ports. I suspect that soon MacOS will disable this capability.
I already run Linux everywhere, MacOS is just what the corporate folks indicate is an acceptable alternative to Windows 10, which doesn't work for me. Once MacOS doesn't work, it will be far easier to argue for corporate issued Linux laptops.
Alienating DevOps, developers, hpc/ai folks ... not really a good idea. But hey, Apple does Apple, so why not.
