Yes, let's alienate the group of people who build 3rd party software and want a reasonably priced headless mac, and user upgradeable memory/HDD. Idiots.
$100+ billion in cash or marketable securities and total spite for the dev/performance market. Just blind arrogance at this point - 'we don't need to offer this option anymore'
Previously there was the XServe platform that I could have in a rack along my other infrastructure. They ditched that. The old MacPro's you could install in a rack, though they were massively overpriced for what it was a purely CPU-bound job. Now the new MacPro's are not rackable any more.
Mac Mini's were never great, but they were cheap enough you could buy a few and small enough that you could put somewhere, although it sucked.
Lately I've been playing with a setup that builds a cross-clang on FreeBSD to cross-compile OS X software using the libraries inside the XCode sdks. The setup itself is working reasonably well, but most autoconf scripts don't work well with cross-compilers, so it's not workable for pkgsrc right now (though it is workable for my own C software). Unfortunately, this would not help with integration testing...
I suggest you take a breath, and maybe a walk. This is not worth getting angry about.
