       | An excellent software project, preservation is a personal
       | favorite ;). I had a look over the blog and GitHub project - but
       | I have one important question that I could not find an answer
       | for: "Which version of macOS is targeted?"
       | 
       | I would assume only the latest or near-latest version, though it
       | is mentioned in this post that they were only recently able to
       | sync source code up to macOS 11.5 (from August 2021).
       | 
       | My theories: either they aim to support a wide array of macOS
       | versions (like Wine), or adopt a "moving target" approach,
       | removing old code and stubs that handle old/removed Mac
       | functions.
       | 
       | I am leaning towards my second theory, as it was mentioned in
       | issue #1337 (heh) that Darwin does not have a stable ABI. That
       | sounds to me like an app built for 10.7 Lion would not run at all
       | on 10.14 Mojave... something that is probably true for real Macs
       | as well.

         | 
         | In practice, on real Macs, most apps built targeting 10.7 Lion
         | will work on 10.14 Mojave. Some apps will be a bit buggy but
         | still basically work.
         | 
         | If you asked about 10.7 and Ventura, then I'd give it more like
         | a 50/50 chance the app would work (possibly via Rosetta 2
         | depending on your hardware).
         | 
         | Backwards compatibility on macOS is quite bad, and it has
         | gotten _much worse_ in the last few years in particular, but it
         | 's not quite _as_ bad as some seem to imagine.

       | We are choosing between Darling and using Mac instances in AWS
       | for validation of ClickHouse builds:

       | 
       | The fact that Darling requires a kernel module makes it quite
       | challenging to use. But the task is open, and I check it once a
       | year.
       | 
       | Overall I'm highly impressed that this is even possible!
       | 
       | Also, I had another idea for builds validation - use a custom
       | version of libc and compiler flags to make the API and ABI on
       | Linux similar to what is on Mac. For example, to make uint64_t
       | unsinged long long instead of unsigned long.

         | Good news: this article announces that the kernel module is no
         | more, since last year apparently!

           | made and have had 0 issues (at least none that was unique to
           | it). My main complaint is that the go compiler doesn't work.

       | Darling is a pretty impressive project. I checked it out a few
       | years ago and was able to get an old 32bit osx program running on
       | linux, which was pretty cool to say the last. The amount of work
       | that goes into stubbing and reimplementing all the frameworks is
       | pretty mind boggling though, I'd commend anyone who takes up such
       | a mammoth challenge.

       | I'm not sure who the intended audience is for this post, but if
       | it's the general programmer audience I have several suggestions:
       | 
       | 1. Explain what the project is right at the start. I had to go to
       | the main website to find out (run macOS software on Linux.)
       | 
       | 2. Follow with a high-level summary. What does all this work mean
       | for the user? Can I now run more software than I could
       | previously?
       | 
       | 3. Put the most important things first. Is updating your blog
       | really the most important thing you've achieved in the last four
       | years?

       | If you're like me and had 0 idea what Darling is a few paragraphs
       | in:                  Darling is a translation layer that lets you
       | run macOS software on Linux             Wine lets you run Windows
       | software on Linux, and Darling does the same for macOS software.
       | [...] we finally have basic experimental support for running
       | simple graphical applications.

         | What always annoys me about these blogs is that they have no
         | obvious link to the main site, it all just goes to blog
         | homepage which doesn't bother explaining itself.
         | 
         | This is fine for personal blogs where I don't really care who
         | you are, but it does for projects and companies. (And personal
         | sites often prominently feature About page so it isn't even a
         | problem)

       | Does darling allows the same? A have a Mac license which could be
