The nasty macOS failure is not “app will not launch.” It is: Clash Verge Rev has quit or its core has stopped, yet Safari/Chrome time out as if the Mac has no network. Often system proxy still points at 127.0.0.1 on a port that no longer listens—traffic falls into a black hole. Clash Verge Rev v2.5.6 (2026-09-26) lists a fix for “system proxy left on a dead port after the service-mode core stops unexpectedly,” plus leftover service processes blocking core start / “continue with Sidecar,” group-resolution failures, and clearer refusals when the home directory lives on an external volume. Notes: v2.5.6 release. Builds: download center.
Gatekeeper “damaged” is another track: macOS cannot open. Generic post-uninstall cleanup: uninstall cleanup. This page stays on leftover service, Sidecar, external volumes, and dead proxy ports—and how to verify on 2.5.6.
Get online first: sixty seconds on dead system proxy
Before anything else, confirm the symptom is a dead local proxy rather than a dead upstream. The browser is not “stuck loading”—it is sending every request to a port that nothing answers, so each connection times out.
- System Settings → Network → your interface → Details → Proxies.
- Check whether web proxies still point at 127.0.0.1 and a port (often the mixed port).
- If Clash is not running, clear those checkboxes, Apply, retry the browser.
Pages return immediately → you confirmed a dead local proxy, not a dead airport. Port field reference: mixed port. Broader system-proxy guide: system proxy not working.
You can reveal the same state from the terminal, which is handy when the GUI is sluggish:
networksetup -getwebproxy "Wi-Fi"
networksetup -getsecurewebproxy "Wi-Fi"
# Enabled: Yes Server: 127.0.0.1 Port: 7890 => dead if Clash is off
Which macOS pits v2.5.6 actually names
From GitHub Release v2.5.6:
- Leftover service processes: block core start and “continue with Sidecar.” Easy to misread as a bad dmg.
- Cannot resolve user group: some accounts fail install/repair; retry the official service flow on 2.5.6.
- Home on an external volume: clearer refusal text and repair-command direction when the service will not start the core.
- Dead system proxy after service core stop: old behaviour left HTTP(S) proxy on a port that no longer listens—global “no internet” with the app already gone. Strong upgrade reason.
- Rule editor auto-capitalizing the first letter: editor polish; fewer false YAML hunts.
| Behaviour | Before 2.5.6 | On 2.5.6 |
|---|---|---|
| Core stops unexpectedly | System proxy may stay on dead port | Proxy cleared or no longer points at dead port |
| Leftover service process | Silently blocks core / Sidecar | Recognized; clearer remount path |
| External-volume home | Vague refusal | Readable prompt + repair command |
Core-start and unexpected service-core-stop messages are more concrete, and unresolved errors resurface after the window recovers—read them before relaunch spam. Windows cousins: Windows service/isolation/TUN checklist.
Leftovers and Sidecar: judge, then verify
- Quit cleanly; if needed, end recognized Clash Verge / core processes in Activity Monitor only.
- Over-install v2.5.6 (do not mix Intel and Apple silicon packages); confirm About.
- Install or repair Service Mode when required; finish group-resolution or external-volume prompts before enabling TUN.
- Deliberate fault test: enable system proxy → browse → kill the core/service path → confirm proxy is cleared or no longer points at a dead port. Pre-2.5.6 this step often left you offline.
TUN still failing: Tun start failed and Tun mode—do not hammer Sidecar. Log tokens: logs guide.
External-volume home directories
Homes on USB/Thunderbolt disks hit stricter background-service path rules: GUI opens, service-mode core refuses, prompts used to be vague. v2.5.6 makes the refusal readable. Practically:
- A/B with an internal-disk user to separate “external volume policy” from subscription issues.
- If you must stay external, follow the new prompt’s repair commands, then re-check service and system proxy.
- Do not change subscription URL, Merge, and DNS in the same experiment.
Acceptance and stop rules
Run the steps top to bottom, then confirm every line below. If any one fails, stop and re-read the related post instead of rebooting blindly.
- About shows 2.5.6; package matches chip.
- After a normal quit, system proxy must not point at a dead port.
- Core starts on service/Sidecar paths; Connections shows rows.
- External-volume users who were refused get readable prompts and a clear next step.
Still offline: proxy panel first, then uninstall cleanup, and only later safe reset. Facts follow the GitHub Release; the news post answers “should I upgrade,” this page answers “which clicks when the Mac looks dead.”
