Hi, I'm shiichan! There's a new beta out for the Cloudflare One Client on macOS, so let me walk you through it!

What was announced?

According to the Cloudflare Changelog, a new beta of the Cloudflare One Client (the WARP client) for macOS, version 2026.7.1210.1, is now available. You can grab it from the beta releases downloads page — this is a pre-release build meant for early testing, not general rollout.

The story so far

The Cloudflare One Client has had a few rough edges around connectivity. For example, when HTTP/3 gets blocked after the QUIC handshake, the client didn't always switch protocols smoothly. Some users also saw a certificate error pop up right after a connection was successfully established, even though nothing was actually wrong. And a failure to parse the DNS search domain could block the connection entirely. Small things, but the kind that get annoying fast in daily use.

What changes

This beta bundles fixes for exactly these kinds of connectivity issues. Protocol switching is smarter now, the false error messages are gone, and DNS handling is more resilient. For IT admins and anyone relying on this client day to day, that adds up to a noticeably more stable tunnel experience.

Dive Deep

There's a good list of fixes and improvements in this beta, so here they are:

  • Improved connection reliability: the client now swaps protocol order after repeated connectivity-check failures, which helps when HTTP/3 is blocked after the QUIC handshake
  • Fixed a certificate error display bug: a certificate error could be incorrectly shown right after the connection is established
  • DNS search domain parsing fix: a parsing failure no longer prevents the connection from being established
  • Fixed a MASQUE tunnel stall: the tunnel could previously stall while uploading at a high rate
  • Fixed organization switching: users could get stuck unable to switch organizations while in the "Device not in organization" state
  • Fixed the Home Screen dropdown popup not anchoring correctly
  • Fixed a crash during dialog dismissal
  • Increased tolerance for large local domain fallback resolver lists: DNS resolution now behaves correctly even with more fallback resolvers configured than recommended
  • Fixed the client stealing window focus, for example during reauthentication
  • Fixed a crash when connecting to a captive portal over Wi-Fi
  • Fixed a system tray/UI status mismatch: the tray icon could show "disconnected" while the UI showed "connected"
  • Device profile re-evaluation on successful reauth
  • More efficient dashboard-managed client updates: the updater now only runs when needed

Wrap-up

Here's what stands out in this beta:

  • Big improvement to connection reliability, including automatic protocol switching when HTTP/3 is blocked
  • A bunch of annoying bugs fixed: false certificate errors, DNS parsing failures, MASQUE tunnel stalls
  • UI/UX fixes too, like the tray icon mismatch and window focus stealing

If you run the Cloudflare One Client on macOS, especially as an IT admin, it's worth grabbing this build from the beta releases downloads page to try out!
