Use this when macOS apps cannot resolve MagicDNS short names although a direct query to 100.100.100.100 succeeds.
When MagicDNS resolves through dig but macOS apps cannot resolve a short name, inspect /etc/resolver/ for a stale search-domain file from another VPN or DNS tool. In the linked Tailscale report, an EasyTier file remained after EasyTier stopped and sent short-name queries to its resolver.
Compare dig @100.100.100.100 <short-name> with the app lookup, then inspect the files and nameservers under /etc/resolver/ and scutil --dns.
Move or disable only a file you have confirmed is redirecting the affected search domain. Use a destination that exists; do not move unrelated resolver files. Disable the other tool's search-domain integration if it recreates the file.
Flush the macOS DNS cache and recheck the same short name. Use a fully qualified name for domains owned by the other tool.
