view main/SVSplash.cpp @ 2265:d33dff02b39b sandbox-notarize

Work on sandboxing (possibly) and using the hardened runtime for notarization. Supply appropriate bundle ID for helpers as well as main application, and request inherited sandbox entitlements. Currently works with sandboxing (apparently) but not yet with the hardened runtime, where we can't load plugins signed by third parties even with the com.apple.security.cs.disable-library-validation entitlement because their team IDs don't match the host. Possibly that exception is supposed to be requested some other way?
