New macOS releases have historically led to unpleasant surprises, so I decided to run the beta on an older machine. I installed both the beta of macOS and Xcode, and made the latter default using sudo xcode-select --switch /Applications/Xcode-beta.app/Contents/Developer.
Note that Apple switched the default shell to zsh: https://support.apple.com/kb/HT208050
Beta 3
TL&DR: binaries still work, but building QT from source doesn’t and depends seems broken
The existing binary on my system kept working fine. I was also able to download and install v0.18 from bitcoincore.org.
Compling master (536590f358dc3d3e5821eba7f1009452ea93b205) from source source fails, see (log).
Using Homebrew with boost 1.70.0 and qt 5.13.0.
The tests produce a bunch of warnings:
0test/util_threadnames_tests.cpp:64:5: note: in instantiation of function template specialization 'boost::test_tools::tt_detail::check_frwd<boost::test_tools::tt_detail::equal_impl_frwd, unsigned long, int>' requested here

These warnings also occur in the Solaris problem in #15708.
QT produces warnings:

I can ./configure --without-gui and run the test suite.
I reinstalled all of homebrew, but still get the above warnings and errors.
Using depends instead, I’m unable to build protobuf (see log). When I strip out protobuf, Boost fails in the same way as #13601 (log). However in this case xcode-select --install doesn’t make the issue go away, and the other workaround /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg no longer exists. See also this dicussion.
