jasonxue	I can use it normally the day before yesterday, but when I run `sudo darwin-rebuild switch` yesterday, it failed and told me this message. I try to reinstall nix and reinstall macOS. But it tells me the same. My Mac is macOS 10.12, it’s MacBook pro 2016. Here is the output: `jason@jason-MacBook-Pro:~/ > nix dyld[1153]: Symbol not found: (__ZTVNSt3__13pmr25monotonic_buffer_resourceE) Referenced from: '/nix/store/y8v9ariyblm29ypgsq5i1vf8xsrfsm3q-nix-expr-2.31.2/lib/libnixexpr.dylib' Expected in: '/usr/lib/libc++.1.dylib' zsh: abort nix jason@jason-MacBook-Pro:~/ >` I need help, thanks. I use Determinate and use upstream nix. When I uninstall nix Darwin, it’s normal.

jasonxue	VERY THANKS	15:11:05
Xwy	Redacted or Malformed Event	17:16:08
Randy Eckenrode	niklaskorz: Thanks for the review on the SDK bump. It’s stuck on some codeowners check. I’ll have to look at it later when I'm back at home.	17:22:50
Randy Eckenrode	(Unless someone has seen this and knows what the problem is.)	17:23:13
niklaskorz	It's likely related to the GitHub outage today	18:33:05
niklaskorz	Many PR checks are failing	18:33:14
@ieda:matrix.org	all checks are passthru.tests today, it seems	18:54:39
@ieda:matrix.org	taking forever	18:55:46
samasaur	oh by the way i did test out macros with swift 5.10. They fail with a missing CompilerPluginSupport module, which i was able to fix, but then the example macro package i was building failed with different errors. I do want to get macros working, but given that macros weren't introduced until 5.9 this has met my goals of "no more broken than before" and i think the PR is ready to review as is, especially considering this whole PR is kinda a stopgap until Randy's rework	19:49:33
Randy Eckenrode	I got macros working on my branch (since they’re required by Swift Testing), but it wasn’t pretty IIRC.	19:51:04
	tavinator joined the room.	22:18:13
Randy Eckenrode	The Darwin SDK bump has been merged. The minimum supported version is now 14.0. The default SDK is 14.4. Use of older SDKs will throw. All packages using `apple-sdk_11`, `apple-sdk_12`, `apple-sdk_13`, and (most of) `apple-sdk_14` have been cleaned up to use the default SDK. Swift currently throws, but is working on an update to Swift 5.10.1 that will fix it.	22:38:35

samasaur	oh, duh. macros won't work because they need swift-syntax, which needs a host swift at the time of building swift	02:47:39
samasaur	in that case my PR really is done	02:56:36
