Great, thanks! So the next steps here are: 1. Send an email to dev-platform and announce our intent to switch to the macOS 11 SDK, with justification and action steps. (Action steps: Developers on 10.15+ need to update Xcode to at least version <insert version here>, and switch their `--with-macos-sdk` flag to the macOS 11 SDK (or remove the `--with-macos-sdk` declaration altogether). Developers on 10.14 and below need to update macOS or obtain the macOS 11 SDK.) 2. Ask glandium to write a patch to use the macOS 11 SDK in CI. 3. File a bug to require the macOS 11 SDK for building. 4. File a bug to remove [any code that's only needed for old SDKs](https://searchfox.org/mozilla-central/search?q=MAC_OS_X_VERSION_MAX_ALLOWED&path=&case=false®exp=false). Haik, do you want to do that?
