New macOS releases have historically led to unpleasant surprises. I’m running the beta on an older machine, so I’ll post testing progress here. Most problems deserver their own issue. See #16387 for Catalina beta testing last year.
I consider Universal Apps out of scope for this issue.
I removed Homebrew and PyEnv first, installed Xcode 12 beta, before reinstalling them. This best represents what the actual OS will look like with a clean install. It also prevents Homebrew from installing Xcode 11 developer tools.

Beta 1
Build: 20A4299v on Intel CPU, using Xcode 12 beta (without Universal App support).
Downloading 0.20 binary from bitcoincore.org works fine (with right-click install).
Tested master @ 19612ca2eb2e335c8ccc9c0f33421df22f1cc3b6
I didn’t test ZMQ and libmultiprocess yet.
Without depends
First I installed dependencies using homebrew 2.4.2. I use --build-from-source to see if there’s any homebrew packages that probably need a Big Sure specific update . That revealed with a few problems.
Installing Python via PyEnv doesn’t work yet (see https://github.com/pyenv/pyenv/issues/1643), but you can install the binary for now, or via homebrew.
Brew can’t install berkeley-db4 using --build-from-source, but it can use the Catalina bottle.
clang crashed for test/test_bitcoin-scheduler_tests; I sent a bug report to Apple, attached logs for @practicalswift and other compiler aficionados. I wasn’t reproducible, not even after git clean -dfx.

With depends
I was unable to build QT the first time, but can’t reproduce that problem. BDB may need a patch (#19411). During blockchain download catchup, I got a LevelDB read failure: Corruption: block checksum mismatch error. I’ll see if I can reproduce that. See #19410.
